Now you can drill holes into metal and other surfaces in hard to reach areas you couldn't get to before without breaking off the tip of a good drill bit. These durable drill bits are precision ground from one piece of M2 High Speed Steel; there is no weak spot where two pieces are welded or crimped together. With a standard 135 degree tip, these bits are ideal for drilling into metal, plastic, or other materials. Ranging in length from 1.9"(33mm) to 2.3" (58mm) overall length, StubbyBits™ let you drill in confined spaces and around tight corners. The shank is 1/4-Inch hex shaft that works with standard quick change chucks. Use with a Drive90™ right angle driver from Milescraft® to get inside of really tight spaces.
