19-Piece Titanium HSS Twist Drill Bit Set with 1/4-Inch Hex Shanks in 13 Metric Sizes from 1.5 to 6.5 mm
A 19-piece titanium HSS twist drill bit set combines quick-change 1/4-inch hex shanks with 13 metric diameters from 1.5 to 6.5 mm. YXYL fully grounds each cutting edge and uses 135-degree split points to self-center during compatible drilling without a pilot hole.
Two spiral flutes clear chips while the titanium-coated high-speed steel reduces friction during light workshop, DIY and repair tasks. Six frequently used diameters include one backup bit each, bringing the 13-size assortment to 19 pieces. Size markings on the shanks simplify selection, and the precision-machined hex profile fits compatible power drills, impact drivers and quick-change chucks. The bits are intended for mild steel, carbon steel, sheet metal, solid wood and general plastics; they are not designed for hardened steel, stainless steel, glass, ceramic, concrete or masonry. Match speed to the material, clamp the workpiece, use cutting fluid where appropriate for metal and wear eye protection. Clear chips with the tool stopped and store every clean dry bit after cooling.
