HT 800 WP Application Recommendations
All data are approximate values. The actually achievable cutting speeds and feed 2/3 xd1 # 4111Tol. m7
rates depend on the respective machining conditions. # 4112/4113/4114
We recommend suitable drilling trials.
~0,01
• for through holes supporting lands must remain in permanent contact. In addition, we recommend reducing
the feed rate prior to exiting. 150°
140°
• 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.
