Feature(may vary by option.)
●Uses better quality materials: the step drill is made of high-hardness HSS 6542, which is perfect for metal and can drill stainless steel up to 1.5 mm, which is not possible with other inferior HSS 4241 step drill bits on the market.
●Wide range of applications: our cone drill can be used for metal, stainless steel, aluminium, copper, plastic, plexiglass, wood and other materials.
●15 steps: you can use a step drill at any time to drill suitable holes in sizes 4-32 mm. (4mm/6mm/8mm/10mm/12mm/14mm/16mm/18mm/20mm/22mm/24mm/26mm/28mm/30mm/32mm)
●10 mm triangular shank: Our cone drill can be used for all cordless screwdrivers, hand drills and drills, and the 10 mm thick design is less likely to break.
●Instructions for use: when drilling metal and other materials with high hardness, the step drill is easy to smoke at high temperatures, you need to add cutting liquid or water to continuously lower the temperature, which can effectively extend the life of the step drill, otherwise it will lead to softening and discolouration of the step drill. The larger the drilling diameter, the lower the speed should be to better protect the cutting edge.
●Professional customer service: you will receive lifetime warranty and 24 hours customer service, if you have any dissatisfaction with the step drill, please contact us, we will do our best to give you a satisfactory answer!

Description
Please read the following instructions carefully to avoid unnecessary problems!
The thickness of stainless steel must not exceed 1.5 mm. If you want to drill materials with high hardness such as metal and stainless steel, please use a drill. (Drilling with a hand drill can be very difficult). The higher the hardness of the material and the larger the diameter, the lower the speed should be regulated. When processing materials with high hardness, water must be continuously supplied for cooling, otherwise the step drill will be greatly worn
