HT 800 WP - Technology and Advantages
With the new HT 800 WP interchangeable drilling system Guhring provides high-perform-
ance and cost-efficient holders for holes in the diameter range from 11.00 to 25.5 mm that
excell thanks to the following advantages:
Extended tool life
Thanks to special, micro-machined cutting edges and the application oriented surface finish the interchangeable
inserts of the HT 800 WP drilling system are especially wear resistant.
The holders of the HT 800 WP drilling system also possess a very high wear resistance. This is based on the
optimised holder material with nickel plated surface as well as incremental holder sizes in steps of 0.5 mm. This
leads to less wear on the holder body.
Optimised chip flow
Thanks to their flute cross section the holders of the HT 800 WP drilling system ensure optimal chip evacuation from
the hole even with larger drilling depths.
Perfect cooling lubrication
A perfect cooling lubrication is ensured by coolant ducts with maximum cross section, exiting in the flute. Thereby
enabling an optimal cooling lubrication of the cutting edges and additionally support the chip evacuation from the
hole.
Highly accurate and rigid insert seat
The accurate insert seat enables the insert change in the machine in only a few, simple steps with a standard Torx
screw driver. Thanks to the optimised material for the holders of the HT 800 WP drilling system, the insert can be
changed more frequently than with conventional systems before the holder needs to be replaced due to wear of the
insert seat.
The clamping screws with screw lock ensure a secure holding of the interchangeable insert in the holder even with
machines subject to high levels of vibrations.
Rigid holders
The close stepped diameter jumps of 0.5 mm with the holder sizes not only reduce wear. Through the better guid-
ance of the tool in the hole they also increase the rigidity of the HT 800 WP drilling system. Subsequently, resulting
in longer tool life as well as improved workpiece surfaces.

HT 800 WP - Application Tips
Please observe the following notes and recommendations for the application of Guhring‘s HT 800 WP tools:
We recommend when changing the insert to also replace the clamping screw!
Therefore, every holder is supplied with a clamping screw, Guhring no. 4071, and screwdriver, Guhring no. 1612. Every
interchangeable insert is also supplied with a clamping screw, Guhring no. 4071.
When changing the insert please observe the following tightening torques for the clamping screw. Adhering to them is
absolutely necessary for optimal machining results!

HT 800 WP interchangeable inserts are in respect of tool material, geometry and surface finish perfectly adapted to
your specific range of application. Subsequently, you will always achieve optimal machining results with maximum
performance and highest economic efficiency.
The insert change with HT 800 WP can be performed in the machine problem-free, the interchangeable insert always
sits perfectly clamped and positioned in the holder.

HT 800 WP Interchangeable Inserts
Complete compatibility
The new interchangeable inserts as well as the new holders of the HT 800 WP system are fully compatible with the
conventional HT 800 WP interchangeable inserts and holders. You can, therefore, apply the new interchangeable
inserts in the already existing HT 800 WP holders or combine new holders with existing interchangeable inserts.
Drilling tests with both combination possibilities have shown that the efficiency of each package lies above the values
of the old HT 800 WP system. You will definitely benefit!
The pilot insert 4111 can be combined with any holder, if the application requires a 150º point angle.

HT 800 WP holders offer highest accuracy and rigidity. The open flute together with internal cooling guarantees an
optimal chip evacuation particularly from deeper holes. The reinforced shank to DIN 6535 HE ensures the strong and
accurate clamping of the holder in the tool holder. As it meets the DIN standard for solid carbide monoblock tools, a
problem-free changeover to the HT 800 WP system in production is possible at any time.
HT 800 WP Interchangeable Insert Holders
Special tools
In addition to our HT 800 WP standard tools we also supply HT 800 WP stepped
tools as well as alternative coatings for HT 800 WP interchangeable inserts as
special solutions. Special sizes up to ø 40.00 mm are available on request.

All data are approximate values. The actually achievable cutting speeds and feed
rates depend on the respective machining conditions.
We recommend suitable drilling trials.
For selecting the optimal tool and the recommended cutting parameters for your
application there is also an electronic version of GühringNavigator available at www.
guehring.de
• for through holes supporting lands must remain in permanent contact. In addition, we recommend reducing
the feed rate prior to exiting.
• for drilling depths from 5xD we generally recommend centring or pilot drilling with holder, Guhring no.
4105, and pilot insert, Guhring no. 4111. Alternatively – depending on the material to be machined – Ratio
drills type RT 100 U or RT 100VA can be applied.
• for drilling without centring we recommend reducing the feed rate at the start of the hole.
• don‘t apply drilling tool without trial for interrupted cutting (grooves, transverse holes). For interrupted
cutting (max. 0.2 x D) it is recommended to reduce the feed rate whenever possible.
• in contrast to conventional indexable inserts, HT 800 tools are also suitable for the drilling of stacked sheets.
• on a lathe (stationary tool) it must be ensured that the tool is accurately centred.
• pre-condition for optimal machining results is a sufficient cooling lubricant supply with soluble or neat oil.
• the tool is only of limited suitability for dry machining or MQL. For MQL application we recommend the use
of the conical MQL shank end as well as Guhring MQL components. Please contact our Sales Management.

HT 800 WP Application Recommendations
• for through holes supporting lands must remain in permanent contact. In addition, we recommend reducing
the feed rate prior to exiting.
• for drilling depths from 5xD we generally recommend centring or pilot drilling with holder, Guhring no.
4105, and pilot insert, Guhring no. 4111. Alternatively – depending on the material to be machined – Ratio
drills type RT 100 U or RT 100VA can be applied.
• for drilling without centring we recommend reducing the feed rate at the start of the hole.
• don‘t apply drilling tool without trial for interrupted cutting (grooves, transverse holes). For interrupted
cutting (max. 0.2 x D) it is recommended to reduce the feed rate whenever possible.
• in contrast to conventional indexable inserts, HT 800 tools are also suitable for the drilling of stacked sheets.
• on a lathe (stationary tool) it must be ensured that the tool is accurately centred.
• pre-condition for optimal machining results is a sufficient cooling lubricant supply with soluble or neat oil.
• the tool is only of limited suitability for dry machining or MQL. For MQL application we recommend the use
of the conical MQL shank end as well as Guhring MQL components. Please contact our Sales Management.
