01POWER DRILLS & ACCESSORIES
Precision drilling from four to thirty-two millimetres
A single tool that replaces a drawer full of standard bits, this step drill bit handles the transition from fine detail to broad opening with quiet confidence. Its conical profile allows you to stop at any diameter along the shaft, keeping your workbench clear and your project moving.
Designed for steel, aluminium, wood and plastic, it suits makers who value efficiency and precision. The nitrogen-treated surface manages heat, while the double-fluted design ensures clean, burr-free edges every time.
02MATERIALS
Titanium coated high speed steel construction
The core is forged from 4241 high-speed steel, a material chosen for its ability to maintain hardness under friction. A titanium coating covers the exterior, reducing drag between the bit and the workpiece. This combination lowers heat generation during extended use, preserving the edge geometry and extending the functional life of the tool compared to uncoated alternatives.
04DETAILS
Nitrogen treatment and spiral scale markings
Beyond the coating, the steel undergoes nitrogen treatment to enhance surface hardness. Engraved scales run along the spiral grooves, providing immediate visual feedback on the diameter being cut. The handle features a 10mm triangular round profile, offering a secure purchase for hand drills or bench setups, ensuring control even when applying pressure to thicker materials.

About this product
HSS Step Drill Bit – – Our step drill bit is mainly designed for drilling in wood and steel, including metals, aluminum, wood, plastic, etc. Superior Material – – Titanium coated 4241 (HSS) high speed steel reduces friction. They are more durable than uncoated drill bits and HSS (high speed steel) has a long service life. Multifunctional – – According to the need to process holes of different diameters, no need to change drill bits and hole positioning, double cutting blade design for faster cutting, automatic deburring of the hole when drilling. Usage – – 4mm precision holes can be drilled to 32mm holes of different sizes. Suitable For – – Drilling tools, bench drills. Working in water cooling can effectively extend the life of the drill bit. Feature – This drill bit is made of high quality HSS steel and with titanium coating to reduce friction and heat. – Suitable for drilling holes in a variety of materials, including steel, brass, wood, plastic, etc. – No pilot holes or pre-drilling required, and automatically deburrs holes when drilling. 2 fluted edges for faster, smoother cutting. – According to the need to process holes of different diameters, you can achieve spot processing of large holes, no need to change drills and hole positioning. – Tool use: drilling, bench drill.
