TOP DRILL S for Steel
™
TOP DRILL S for steel is a high-performance solid carbide drill with an
application-specific design. Although the point geometry is strong enough
to drill stainless steel and cast iron, it is engineered to maximize performance
when drilling steel. The WP20PD grade, designed to resist high heat and
™
wear, is the latest in WIDIA technology. The two-margin design facilitates
™
excellent hole quality and less friction when drilling steel at high speeds.

TOP DRILL S for Cast Iron

TOP DRILL S for cast iron is designed with application-specific point geometry
for maximum performance in cast iron materials. The point features corner
chamfers that minimize breakout on exit holes. A four-margin design improves
hole straightness, increasing tool life and extending cross-hole and inclined
exit capabilities when drilling tough cast iron. The technologically advanced
™
WK15PD grade is specially engineered to withstand high wear.
