Dormer Drill Bit, Right-Hand Rotation, Steam-Tempered Finish - A110 Series - A110 4.2MM

Hunting for a tool that helps you bore holes in hard-to-reach areas? This drill bit from Dormer has got your back. As it's made of rugged HSS that stands up to impact and wear, it's a great shout if you're working with tough materials such as steel or cast iron. A 118° drill point means it's a cinch to regrind if the edge becomes worn through heavy use, giving you long-lasting performance.
