SERIES 33 Three Flute End Mills
www.kyocera-sgstool.com
Solid Carbide Tools
AB
Stepped Core Design
Increased chip space at the axial end of
the tool for aggressive slotting, improved
rigidity, and optimized chip formation.
A
Proprietary Variable Geometry
Engineered variable helix and pitch
conguration offer chatter and vibration
suppression.
B
Using the latest in engineering design and grinding capabilities, Series 33 High
Performance End Mills are ideal for aggressive ramping, pocketing, and slotting in
difcult to machine materials such as Stainless Steel, Titanium, and Inconel. Designed
for applications challenged by heavy chip evacuation, this 3-Flute design offers
increased chip clearance and a reduction in harmonics.
• Proprietary 3-Flute design allows for more controlled chip formation and efcient
chip evacuation.
• Specially engineered stepped core design provides stability for aggressive
ramping and rigidity when utes are completely engaged.
• Open design at the axial end accommodates material ow and load reduction
during operations.
• Variable geometry design provides superior chatter and vibration suppression
during aggressive milling.
• Available with KSPT Patented Jet Stream Technology for precise coolant placement.
• Exclusively coated with Ti-NAMITE-A, which helps to prevent edge build-up while
ensuring superior wear and enhanced tool life.
Series 33 is exclusively available with
the abrasive resistant AlTiN hard coating,
Ti-NAMITE-A. With excellent thermal and
chemical resistance, Ti-NAMITE-A allows
for dry cutting and improved performance
of carbide. Thecoating has a high hardness
ensuring the ultimate protection against
abrasive wear and erosion. Ideal for cast
iron, high temperature alloys, titanium,
steels, and stainless steel applications.
Hardness (HV): 3700
Oxidation Temperature: 1100°C / 2010°F
Coefcient of Friction: 0.30
Thickness: 1 – 4 Microns
(based on tool diameter)
THE SERIES 33 IS IDEAL FOR AGGRESSIVE
RAMPING, POCKETING AND SLOTTING
IN DIFFICULT TO MACHINE MATERIALS:
•
Aerospace Structural Components
•
Medical Implants
•
Automotive Performance Components
•
Stainless Steel Valves
Symmetrical End Gashing
Superior balance combined with a high level
of strength and ramping capabilities.

BACKGROUND
The hook plate is a primary support piece of a fork lift
assembly and requires precise machining tolerances. The
application calls for machining .230” from the peripheral
of the part at an axial depth of 1-1/2”: the A514 material
used in this application is similar to 4140. The competitor
tool was performing this in four rough passes followed by
a single nish pass. KYOCERA SGS Precision Tools (KSPT)
proposed a single roughing and nishing pass utilizing a
1” Series 33 End Mill.
GOALS
The primary goals of this test were to reduce cycle time,
increase tool life, and decrease overall tooling cost.
STRATEGY
Working with the end user to understand their needs, KSPT
approached the application with a 1” three ute Series 33
End Mill, allowing for increased tool life and greater feed
rates to improve cycle times.

RESULTS
The changes made to the application combined with the high performance geometry of the
KSPT Series 33 End Mill resulted in an annual gain of 104.25 production hours. In addition to
meeting the goal for improved cycle times, tool life was increased from 20 to 240 parts per
tool. This reduced the tooling cost per part by 91%, allowing the end user to achieve a total
annual cost savings of $263,100.

CONCLUSION
KSPT was able to achieve the pri-
mary goals of cycle time reduc-
tion and decreased tooling cost
by recommending a high per-
formance tool for the applica-
tion. This allowed for increased
feed and speed rates, resulted in
greater metal removal rates and
drastically improved tool life.
