Solid Carbide Drill
Description
The Solid Carbide Drill with SGL-Point Geometry brings unprecedented drilling success to manufacturers in the aerospace and energy industries.
The B21*SGL solid carbide drill with coolant-through is designed for stainless steel, nickel, and cobalt-based alloys. With patented point geometry and monolayer PVD AlTiN coating, it delivers improved productivity and longer tool life for aerospace and energy applications requiring predictable, high-production drilling.
One of the problems with these materials is their tendency to stick to the cutting tool, leading to built-up edge and corner chipping. The B21*SGL´s proprietary gash geometry, polished cutting edge, negative rake corner margin, and chip-friendly flute design mitigates these effects, while encouraging chip evacuation and reducing cutting forces. Add to that Kennametal´s extremely wear-resistant, high aluminum content KCMS15 grade and you have a drill that not only makes more holes per tool but does so more quickly and predictably.
The B21*SGL gash geometry has a constantly increasing rake angle, providing smooth chip formation and reduced cutting forces, and an outer margin designed to prevent chipping.
Scrapping an expensive part like an engine casing due to a broken tool is simply unacceptable. The B21*SGL solid carbide drill from Kennametal delivers high performance and ensures process safety.
