• double spiral flutes for more efficient swarf clearance; 1/4 Inch hex Shank with quick release slot to eliminate slipping; Self-starting for clean holes in thin materials; M35 cobalt HSS to cut stainless steel. The step drill bit is made with M35 cobalt. It is ideal for variety of materials from stainless steel, metal, plastic, fiberglass to wood. They also help to enlarge existing holes. M35 HSSCo is a high speed steel alloy made up of 5% cobalt. M35 is similar to M2, but with 5% cobalt added.
• The addition of cobalt increases heat resistance. It is widely used in metal manufacturing because of its ability to resist wear over conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M35 is also less prone to chipping when used for interrupted cuts.

Features :

• 【High Quality Material】：High-speed steel, also known as HSS, is the most common drill bit for metal applications. It incorporates an element with titanium that makes the drill bit harder than a typical HSS bit and thus suitable for sheet metal working and are ideal for cutting non-ferrous metals, plastic, wood board, etc
• 【Extra Automatic Center Punch】：You know how when you try to drill into metal or hard surfaces and your drill bit “walks” no matter how much you think it’s steady? Yeah, we have a tool for that. The automatic center punch has a heavy-spring action, and you simply place the tip where you want to drill, and it punches a slight indentation in the surface. Just enough so that the drill bit won’t walk
• 【118° Split Point】：These step drill bits have a small point angle of 118° and require less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. The larger the point angle, the higher the contact pressure and the centering in the material requires more pressure
