High-Performance Drill for Cast Iron Applications

Description

Designed for high-speed and high-feed drilling up to 8 x D in any ISO-K material, the HPR Solid Carbide Drill provides excellent hole straightness even at the highest cutting parameters. The drill´s patented point thinning, special gashing, and a 143°-point angle provide excellent self-centering capabilities and reduce thrust, keeping the drill running straight even at the highest feed rates. In addition, four margin lands deliver maximum stability when drilling cross holes and inclined exits.

 

The HPR solid carbide drill for cast iron components is available in diameters from 3.0 to 20.0 mm and lengths up to 8 x D. A patented corner radius improves tool life significantly and provides excellent hole quality, meeting a hole tolerance range of IT9 to IT10 while effectively eliminating the workpiece chipping when exiting the hole.

 

The drill´s proprietary AlTiN/AlTiSiN multilayer coating withstands the extreme abrasion and high thermal loads encountered when drilling gray cast iron, ductile iron, CGI, ADI, and GGG. The coating is also resistant against the inclusions and pores commonly encountered in these challenging materials. Ultra-high polished flutes and wide flute cross-section promote efficient chip evacuation and further reduce heat and resulting thermal shock.

 

The HPR drill comes with standard coolant through and with a DIN 6535 and 69090-03 MQL (minimum quantity lubrication) interface. With these features, the drill excels in either wet or dry machining conditions.
