Description
This bundle pairs an Irwin 49612 1/8" brad point drill bit with a matching 1/8" stop collar for drilling stud holes in passenger tires. Set the collar once and every hole comes out the same depth, so studs seat evenly across the tread.
The bit is precision ground high speed steel with a 2-9/16" overall length, a 1-7/16" flute length and a 1/8" round shank that fits a standard drill chuck. Its brad point locates each hole, while spur cutting edges and wide flutes cut cleanly and clear debris quickly. Slide the collar onto the bit, secure it at the depth your stud size calls for, then drill until the collar meets the tread.
This listing includes one 1/8" drill bit and one 1/8" stop collar.
