STRONGARM BLACK CARBIDE DRILL BIT - 1/4" X 4"

StrongArm has put considerable effort into this drill bit - StrongArm Black.

This new negative rake bit was designed to compliment the existing StrongArm bits - not replace them.
Experience has shown no one drill bit is the answer to all safe drilling, and different tip geometry can
perform more efficiently on different barriers. The unique negative rake tip of the StrongArm Black
performs superbly on hard plate such as GSA Black Label containers.

“When the going gets tough - the tough use StrongArm Black safe drill bits!”
