HSS Stepped Drill - - Our stepped drill is primarily intended 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 drills and HSS (high-speed steel) has a long service life
Multi-use - - Depending on the need to process holes with 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
Application - - 4 mm precision holes can be drilled in 32 mm holes of various sizes
Suitable for - - Drilling tools, pillar drill. Works with water cooling, can effectively extend the life of the drill bit
Function
- This drill 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 or pre-drilling holes are required and automatically deburrs holes when drilling. 2 fluted edges for faster, smoother cutting.
- Depending on the need to process holes with different diameters, you can achieve point processing of large holes, no need to change drill bits and positioning of the hole.
- Use of tools: drilling, pillar drill. Works with water cooling, can effectively extend the life of the drill bit.
