19-Piece Titanium HSS Twist Drill Bit Set with 1/4-Inch Hex Shanks, 1/16 to 1/4-Inch Sizes and Case
A 19-piece titanium HSS twist drill bit set covers common small-hole tasks in home repair, woodworking, hobbies, and general building. The 135-degree split points help bits start without walking, while sharpened edges and spiral flutes cut and clear chips to reduce heat, friction, chatter, and rough burrs.
The AUYAARS set uses 4241 high-speed steel with a titanium coating and standard 1/4-inch quick-change hex shanks. It spans 13 diameters from 1/16 through 1/4 inch, with a second bit for six frequently used sizes, producing 19 bits total in an indexed case. The set is suitable as listed for wood, plywood, fiberboard, sheet metal, mild carbon steel, aluminum, PVC, and general plastic, but not hardened steel, ceramic, glass, or masonry.
