Complete Kit or Individual Bits: this listing offers flexible options: get the complete 3-Piece Step Drill Bit Set for maximum versatility, or purchase the exact single bit you need. The set includes 3 most-used sizes: 5-Step (5/32" 1/4" 5/16" 3/8" 1/2"), 9-Step (5/32" 1/4" 5/16" 3/8" 1/2" 35/64" 5/8" 11/16" 25/32"), and 15-Step (5/32" 1/4" 5/16" 3/8" 1/2" 35/64" 5/8" 11/16" 25/32" 7/8" 15/16" 1-1/32" 1-1/2" 1-3/16" 1-1/4")
Professional HSS with Titanium Coating-Made from High: speed Steel (HSS) and enhanced with a titanium nitride coating, these bits maintain hardness and cutting power under high temperatures. The coating significantly reduces friction and heat buildup, increasing durability and providing smoother, faster cuts in tough materials
Self-Centering 118° Point for Precision: the 118° split-point tip design allows the bit to start drilling precisely without wandering or skidding. This ensures cleaner, more accurate holes from the very beginning, saving time and improving your work quality
Laser-Etched Step & Size Markings: each step is clearly laser-etched with precise size markings, allowing you to drill multiple hole diameters with a single bit. This eliminates the need for frequent bit changes, streamlining your workflow for projects like electrical installations or plumbing
Versatile Use on Common Materials: the 1/4" hex shank fits securely into any drill chuck, preventing slippage. The HSS titanium construction is ideal for drilling into wood, plastic, PVC, drywall, and soft metals like aluminum, copper, and thin steel sheets. (Not recommended for hardened steel or cast iron)
