HSS Titanium Coating: Our high-speed steel drill bits, fortified with a titanium coating that makes the drill bit harder than a typical HSS bit, can reduce the friction drill, and perform well in heat, corrosion, and rust resistance. Precision-Engineered Design: The 118° split point tip drill reduces friction, pressure, and heat, making the drill bits long-lasting and efficient. The heat-treated double-edged straight flutes ensure smoother cutting and optimal chip removal Includes: Our assortment comes with 5 drill bits and a combined 50-step sizes ranging from 1/8" to 1-3/8", allowing for a wide range of drilling requirements and precise hole size selection. Automatic Center Punch: Say goodbye to "walking" drill bits with our included heavy-duty spring-loaded automatic center punch. Just place it where you want to drill and it will create a slight indentation to hold the drill bit in place. After-Sales Service: The Aluminum storage box for stepped drill bit is sturdy and easier to carry and store. If you are not fully satisfied with our product for any reason, please contact us for a 100% refund or replacement. Specification:
