The DEWALT Extreme DT5557 set includes 10 HSS step drill bits for metal, with cylindrical shanks. Their tips enable uniform, precise holes without the bit wandering, while their design reduces the risk of breakage. The recess in the cutting edge helps produce cleaner holes without damaging the material.
The three flat shank facets prevent the bit from rotating in the chuck. The size marking above the shank makes it easy to identify. The iron oxide coating enables faster drilling—up to 4 times faster than standard HSS-R drill bits—and provides up to 50% longer service life.
