Feature(may vary by option.)
●(Ultra Hard Material) Cobalt-based HSS step drill is coated with TiAlN Titanium Nitride with hardness HRC89. Improved high temperature and abrasion resistance of step drills
●Spiral Shape: The spiral groove reduces pressure during cutting and improves the cutting situation. Compared to linear types, it is more durable and stable when rotating, and greatly improves the cutting efficiency and cooling efficiency
●Tapered drill for stainless steel: The spiral shape is ideal for stainless steel. Suitable for drilling stainless steel, thin steel plates, aluminum plates, wood, vinyl, resin, etc. It also saves time by drilling and chamfering at the same time
●(Multi-hole diameter): The diameter of the hole is expanded from small holes to large holes, so it can be drilled, enlarged, and processed in various sizes
●[More Accurate Design] Each stage drill is engraved with precision in millimeters for improved work accuracy. The double groove design of the hexagonal axis makes the connection of the step drill and electric drill

Universal Hexagonal ShaftThe 3 blades reduce the burden on the cutting blade for excellent durability.Increased cutting efficiency by increasing the number of times the blade contacts. 3 points of support stabilizes the balance and reduces bibability during cutting. Versatile hexagonal shaft type allows for a wide range of applications. |
Spiral Spiral ConstructionThe spiral shape is suitable for stainless steel with less welding and smooth drilling. The spiral shaped drill creates a deep groove edge and sharp edge. |
Deburring automatically when drilling.Can be widely used for drilling a variety of materials. |
