Set of 33 reduced shank drill bits includes inch sizes 1/2″ through 1″ in 1/64″ increments.
High-speed steel (HSS) provides hardness for wear resistance.
Black oxide finish reduces bit wear while promoting chip and coolant flow on ferrous material.
Self-centering 118-degree split point penetrates material without a pilot hole.
Round shank with flats has three flat sides for better tool grip than a standard round shank.

Set of 16 reduced shank drill bits includes inch sizes 17/32″ through 1″ in 1/32″ increments.
High-speed steel (HSS) provides hardness for wear resistance.
Black oxide finish reduces bit wear while promoting chip and coolant flow on ferrous material.
Self-centering 118-degree split point penetrates material without a pilot hole.

[Specifications and Packaging]: 1 Pc reduced-shank drill bit and 1 pc plastic tube.Include Size:1″..
[Fitment]: Hss drill bit set for metal/ wood/ plastic. Suitable for home DIY, and general building/engineering/woodworking use..
[Material]: Metal drill bit used high speed steel M2 black and gold, resists corrosion, ensures outstanding durability, sharpness and capability, reduces the friction and runs cooler..
[Advantage]: Industrial drill bit Increases cutting speed with self-centering and prevents walking, clears chips and particles faster. The split point tip can increase the wear resistance..
[Special Design 135-Degree]: Cobalt drill bit 135-degree penetrates hard material without a pilot hole and produces small chips to reduce clogging..
