Feature
●Easy to use: The ladder and bit with its unique structure can be opened in various specifications of the opening. No pilot holes required, holes can be created automatically
●[Features] The holes are spread sequentially from small holes to large holes, so you can adjust the holes of multiple sizes and enlargement of the holes. No need to use center punch as compared to normal twist drills that are not easy to break
●Applications: For household DIY, drilling of stainless steel, thin iron plates, aluminum plates, wood, vinyl, resin, etc., enlarging the lower hole, chamfering, deburring, etc
●(Ultra High Hardness) This step drill is made of HSS steel (high speed steel) with a titanium coating on the surface, making it harder than ordinary steel step drills, giving it an outstanding cutting edge. Reduces heat produced during friction
●【Durable and Long Lifespan】Work with water cooling can effectively extend the service life of the bit. Recommended Drill Speed: 250-400 rpm Shank: 1/4" Hex Shank
