Feature(may vary by option.)
●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: Two-flute spiral grooved design deburrs chips, dust and debris for clearance and smooth cutting. The 118° split point tip drill reduces friction, pressure, and heat, making the drill bits long-lasting and efficient.
●Wide Application: Our step drill bit can process different diameter holes, and can be used on materials such as metal heavy-duty, iron, aluminum, brass, plastic, aluminum alloy, wood, plastic, etc. Suitable for home DIY and general use.
●Quick Change: The 1/4-inch hex shank fits easily and securely into all power tools to prevent slippage and shedding during rotation.
