DeWalt DW1640 3" Heavy-Duty Self-Feed Bit
Cut your rough-cut holes in wood faster with DeWalt's self-feed bits.
The two-cutter design is available from the smallest to the largest bit, unlike some of the competition that only uses it on sizes above 3 inches.
The self-feed spur is extremely aggressive and can be replaced.
Flats have been added to the bit shank to eliminate the shank spinning in the chuck.
