3)
Dry machining is not recommended.
Vertical M/C: 1.5D or lessLathe: 3D or less
In case of horizontal M/C
Internal coolant is recommended for horizontal machining center because external coolant may not sufficiently be applied to inside because the tool is revolving.
For installation of DRC type MagicDrill,
use Hydro Chuck, Power Chuck, Collet Chuck, etc.
For side lock arbor, tool life is shortened due to drilling center deviation. Hole shape failure may occur.

1. Due to good chip control, step machining is not necessary for
Low Carbon Steel.
2. When machining SUS304, for hole depths of more than 2.5D,
utilize the step machining process.
3. In order to have smooth chip removal, we recommend
internal coolant.
Stacked
Plates
1. Fix stacked plates securely to ensure they do not slip while
machining.
Hole
Expansion
1. If the overlap amount is less than
1/3 x D, machining is possible.
Concave
Surface
1. When machining concave holes set the feed rates at half or
less than continuous hole machining.

Q&A
Q-3
A-3
Drilling deep hole machining using DRC (8D type), dimension variation of diameters has occurred
at entrance and far (outlet) side possibly due to deflection. Is there any countermeasure?
There are some countermeasures as follows to prevent deflection (to improve bite of drill).
Countermeasures 1
l
Increasing the feed rate
Increasing the feed rate may keep the processing diameters constant.
(Estimated rate: Current rate + 0.03 to 0.05 mm/rev)
If increasing the feed rate is not possible because rigidity of machine or clamp is weak.
Countermeasures 2
l
Make a center spot
1) Make a center spot using the DRC drill or a commercially available center drill
which has a vertex angle of about 140°.
( If the center drill can be modified, make its vertex angle larger than 140°)
2) Then drill the hole using the DRC drill (8D type).

Indication of tool life of MagicDrill
How to judge tool life Indication of judging tool life
Judgement of tool condition
and insert wear
· When an insert is new the toolholder is slightly bent to the side during drilling. (therefore, the drill diameter is slightly
bigger during drilling).Once drilling is finished, the toolholder will return back to normal size. No tool marks will
appear on the finished surface. (although this depends on workpiece and cutting condition: during external drilling
slight tool mark might appear.)
· When an insert is at the end of its tool life, Gradually the external corner part gets worn out, the toolholder does not
bend slightly outwards - it starts to bend inwards. After the drilling is finished, the toolholder returns to the normal
position. When taking off a toolholder under this condition the cutting edge of the insert creates external tool marks
on the finished surface of the workpiece.
Checking hole diameter
When hole diameter is measured, suddenly it shows small diameter.
In this case, a worn out insert can be the cause.
Checking the surface
on the exit side
If insert wear progresses, the burrs of penetrated hole entrance becomes bigger.
This is a clear indication that the tool must be exchanged.
Variation of drilling noise
Light drilling noise at the beginning turns to brady noise which contains vibration noise.
Variation of vibration
As the end of tool life is getting closer, there is more vibration and the drilling noise changes.
However, when drilling smaller diameters these factors are difficult to detect.

Max. Depth for Drilling with Outer Coolant
In case of using outer coolant system, chip evacuation will be bad. Therefore ap should be measured within 1.5 times (1.5×Dc) of drill
diameter(ϕDc).
Drill type 2D~3D 4D 5D
Cutting width (Torus-shaped part) 1/10×D or less Less than corner radius Not recommended

2. Center-Height Adjustment for Lathes
Most Lathe problem occur due to Center Height Deviation.
The Center Height is appropriate if a core approximately 0.5mm diameter
remains at the center of the end face. (Fig.3)
Center-height adjustment is necessary for the case as follows:
No core remains or
Core diameter is more than 1mm
(1) Align the drill with the outer insert face parallel to the X-axis of the tool turret. (Fig.4)
(2) Align the scale (for the lathe) on the ange face of the sleeve to the center of the drill coolant plug.
(3) When no core remains, rotate the sleeve to (+) direction to make the core larger, and when the core diameter is more than 1mm, rotate the
sleeve to (-) direction to make the core smaller.
(4) When rotating the sleeve, insert the wrench supplied with the drill into the hole of the ange and then rotate the sleeve.
(5) After Completing the adjustment, tighten the drill directly through the window on the sleeve.
Note: Depending on amount of the center height adjustment, the hole diameter may change. It is recommended that the hole diameter is
checked after the center height adjustment.
1. Hole Diameter Adjustment when Drilling
(1) Adjust the scale at the ange periphery of the sleeve to the center of the coolant plug of the drill. (Fig.1)
(2) When making the hole diameter bigger, rotate the sleeve in (+) direction and to make it smaller, rotate the sleeve in (-) direction.
(3) When rotating the sleeve, insert the wrench supplied with the drill into the hole on the ange periphery to rotate the sleeve.
(4) Using the bottom screw of the side-lock arbor, rmly tighten on the drill directly through the sleeve’s window.
The upper screw should be tightened slightly so that the sleeve will not be damage.
Caution:
· Not applicable for Collet Chuck
type Arbor.
· Scale on the sleeve is the reference value.
Check the actual hole diameter after adjusting.

Lathe Installation
(1) The top face of the outer insert should be parallel to the X-axis to
allow for offset machining.
Drill diameter can be changed by moving X-axis.
(2) It is recommended to set the outer insert as shown in Fig.1 with the
outer insert facing the operator. (Fig.1)
(It is also possible to use it by setting it in 180° reverse position)
If the lathe has two turrets, when installing the drill into the lower
turret, the outer insert should be set to face the operator.
(It is also possible to use it by setting at 180° reverse position)
¢
Drill Diameter Adjustment
1.Drill Diameter Adjustment
(1) Drill diameter is adjusted by moving X-axis.
The moving direction of the X-axis depends on the position of the toolholder.
(2) In case of making the hole diameter larger, slide the tool along the X-axis toward the outer insert side. (Fig.2, Fig.3)
For making the hole diameter smaller, slide the tool along the X-axis in the opposite direction.
(This movement of the axis is called “Offset”)
However, be sure not to make the hole diameter smaller than the drill diameter by 0.2mm or more. Otherwise, the toolholder will
interfere with the drilled hole. (Fig.4)
e.g.) In case of using ϕ20 drill, the hole diameter must not be smaller than 19.8mm.
2. Offset Limit of the Drill Diameter
For the maximum limit of the drill diameter, refer to “Max. Offset (Radial)” in the Toolholder Dimensions table.
(The figure in the table shows how much it is possible the offset the drill in the radial direction. )
e.g.) In case of using ϕ20 drill, it is possible to make a hole up to ϕ21 since “Max. Offset (Radial)” is +0.5mm.
¢
Center Height Adjustment
1. Center Height of the Inner Insert
When installing inner insert as shown in Fig.1, it will be set around 0.2mm below the Center of
Spindle. (Fig.5)
This is the normal position of the center height and the drill is designed to be handled in this
condition.
However, in case that the turret of the lathe is out of the center of Spindle, sometimes the inner
insert may be set above the center, or excessively below the center.
For stable drilling, it is essential to
2. How to Check the Center Height
For checking the center height of the inner insert, see the core which remains at the center of
the end face of the drilled hole. (Fig.6)
If the center height is in the normal condition, the core about 0.5mm in diameter, will remain
after drilling.
In the following cases, it is necessary to adjust the Center Height.
· No core remains
· Core diameter is more than 1mm
* To test the Center Height, drill a shallow hole about 10mm in depth at low feed rate, less than
0.1mm/rev.

3. Center Height Adjustment
a) No core remains / Core with Excessively Small Diameter
This happens when the Inner Insert is set above the Center Height.
In this case, adjustment is necessary since insert breakage will be probable at the center of
the drill. (Fig.7)
b) Core with excessively large diameter (More than 1mm)
This occurs when the inner insert is excessively below the center.
This condition causes poor chip evacuation and an adjustment is required.
[How to Adjust]
Install the drill rotating 90° as shown in Fig.10.
(outer insert is positioned on the upper side) and
adjust the center height by moving tool in the
X-axis direction.
(However, this makes it impossible to adjust the
drill diameter)
Caution: When installing the drill in the opposite
direction (outer insert is positioned lower), the hole
diameter will become smaller, which may cause
the drill body to interfere with the drilled hole.
The best solution is to readjust the center position
of the turret itself.
[How to Adjust]
(1) Install the drill rotated 180°.
Most problems will be solved by this method.
(Fig.8)
[How to Adjust]
(2) If the core diameter becomes too large after the
above adjustment, install the drill by rotating
90° counter-clockwise as shown in Fig.9 (outer
insert is positioned lower) and adjust the
center height by moving the tool in the X-axis
direction. (However, this makes it impossible to
adjust the drill diameter)
Caution: In case of installing the drill in the
reverse direction (outer insert is positioned
above), the hole diameter will become smaller,
which may cause the drill body to interfere with
the drilled hole.
The best solution is to readjust the center
position of the turret itself.

performance will deteriorate.
If the feed rate is increased too much from above condition, inner edge chip evacuation
will deteriorate.
If the feed rate is decreased too much from above condition, outer edge chip evacuation

)
(2) To adjust to larger diameter, align the +0.1 mark on the sleeve with the at on the drill shank.
To adjust to smaller diameter, align the -0.1 mark on the sleeve with the at on the drill shank. (Fig.1)
(3) Tighten the bottom screw rmly which is directly touching the drill. Slightly tighten the upper screw which is directly touching the sleeve.
The upper screw should be tightened slightly so that the sleeve will not be damage. (Fig.

· Apply a sufficient amount of coolant.
: 1st Recommendation ✩: 2nd Recommendation
e.g.) In case of drilling using DRZ3090-10 (3×D type)
(1) For milling, pre-drilled hole should be cut bigger than ϕ24 (ϕ30-0.1x30x2)
(2) For turning, ap should be set under ap = 3mm (0.1x30)
Max. Depth for Machining with Outer Coolant
l
In case of using outer coolant system, chip evacuation will be bad.
Therefore ap should be measured within 1.5times (1.5xDc) of drill diameter (
ϕDc).

Indication of tool life of MagicDrill (DRS / DRX / DRZ)
How to judge tool life
Indication of judging tool life
Judgement of tool
condition and insert
wear
l
When an insert is new,
The toolholder is slightly bent to the side during drilling.
(therefore, the drill diameter is slightly bigger during drilling.)
Once drilling. is finished, the toolholder will return back to normal size.
No tool marks will appear on the finished surface
(although this depends on workpiece and cutting condition: during external
drilling slight tool mark might appear.)
l
When an insert is at the end of its tool life,
Gradually the external corner part gets worn out, the toolholder dose not bend
slightly outwards, it starts to bend inwards.
After the drilling is finished, the toolholder returns to the normal position. When taking
off a toolholder under this condition the cutting edge of the insert creates external
tool marks on the finished surface of the workpiece.
Checking hole diameter
When hole diameter is measured, suddenly it shows small diameter.
In this case, a worn out insert can be the cause.
Checking the surface
on the exit side
If insert wear progresses, the burrs of penetrated hole entrance becomes bigger.
This is a clear indication that the tool must be exchanged.
Variation of drilling noise
DRX / DRZ
"
Light drilling noise at the beginning turns to brady noise which contains
vibration noise.
DRS
"
Light drilling noise at the beginning turns to whir noise.
Although, it is difficult to recognize DRX / DRZ type's smaller drill diameter or DRS
type's variation of drilling noise because of main motor noise or projection of coolant.
Variation of vibration
As the end of tool life is getting closer, there is more vibration and the drilling noise changes.
However, when drilling smaller diameters these factors are difficult to detect.

Q&A
Q-1
Is it possible to use outer coolant?
A-1
Outer coolant is not recommended because the amount of chips will be
enormous.
Use internal coolant.
Ref. to the graph of “Drill diameter and coolant amount”.
Q-2
What level of spindle output is required?
A-2
Higher output is preferable.
What is important is enough torque rather than high spindle rate.
Ref. to the examples of required power as below.

Q-3
The workpiece material is elastic and the chips are stretched and tangled. Is there any countermeasure?
A-3
When chips of elastic material are stretched and tangled, try “low rate + large feed”, “high rate + small feed” or
other settings.
Chips are usually stretched well between the entrance and 10mm inside, and not any more stretched further
inside. Therefore charging the condition of entrance only will also be effective.
· [Low rate + Large feed]
This setting makes the chips thicker so that they easily break off.
E.g. Vc=80 m/min, f=0.2 to 0.25 mm/rev
· [High rate + Small feed]
This setting makes the chips thinner and uses centrifugal force to cut them off.
E.g. Vc=200m/min, f=0.07 to 0.09mm/rev
· [Step machining at entrance]
E.g. Entrance to 10 mm deep: 1 mm step drilling
E.g. 10 mm deep or more: Vc=150 m/min, f=0.15 mm/rev (Continuous drilling)

Drill diameter (mm)
Amount of coolant
The amount of coolant is obtained by
measuring the coolant after it passes through
the drill and is discharged.
Q-4
Chattering occurs. Is there any countermeasure?
A-4
Chattering usually occurs during chamfering and when the feed rate per revolution is not high enough.
Try changing the cutting conditions as follows.
· Increase the feed rate if it is small.
If the feed rate is f=0.06 mm/rev, for example, increase it to f=0.08 to 0.12 mm/rev.
Increasing the feed rate will improve chamfering and thus prevent chattering.
· If the cutting speed is too high, lower it to Vc=100 to 150 m/min.
· If the chamfering point and pass-through point are not plain, or if the workpiece clamping rigidity is low, lower the
feed rate to f=0.07 to 0.08 mm/rev.
· If chattering occurs on the full contact surface (e.g. during step drilling), make adjustments by increasing the
feed rate during chamfering or lowering the cutting speed.
Once chattering occurs during chamfering, it will continue through drilling.

Q-5
Tool markings are made on the finished surface. Is there any countermeasure?
A-5
During processing, force of deflection is applied to the
center of the drill.
If the drill is just pulled out from the position where
processing is finished, tool markings will be made.
To prevent tool markings, perform offset before pulling out
the drill.
Tool marking
· How to prevent tool markings
(1)
Drilling the hole. (The spindle revolves.)
(2)
Turn back approximately 0.5 mm. (The spindle revolves.)
(3)
Stop revolution and perform offset. (The spindle stops.)
(4) Pull out the drill
