Description
- Premium Materials: This rotary burr set and step drill bit are carefully crafted with high-speed steel and carbon steel, and enhanced by quenching and heat treatment processes. The M35 cobalt step drill has excellent hardness (HSS Co), surpassing the standard HSS4241 drill bit, and can easily complete tough tasks
- Spiral Step Drill Bit Sets: These drill bits adopt a step-cone design (3mm to 13mm), allowing you to drill a variety of hole diameters without changing tools. They are equipped with a 1/4-inch (6.35mm) hexagonal shank, which is compatible with bench drills, impact drills, and hand drills. The 118° X-shaped opening ensures precise drilling without the need to use multiple drill bits
- Rotary Burr Set: This 1/4-inch drill bit set includes five shapes – spherical, oval, cylindrical, large cone, and small cone. With a 1/4-inch (6mm) shank drill bit, it has higher efficiency than hand files and small-shank wheels. These durable burrs are made of high-speed steel and tungsten carbide for increased precision
- Wide range of uses: Ideal for home repairs and light-duty tasks, the M35 step drill bit for metal easily drills through plastic, aluminum, copper, and sheet metal, including stainless steel and hardened steel. The rotary burr set excels at precisely grinding, polishing, and shaping softwood, plastic, and rubber surfaces
- Package Included: This set includes one M35 cobalt step drill bit (3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm) and five rotary burrs (ball, oval, cylindrical, tenon, and cone cutters). A variety of profiles allow wood and metal carvers to shape and cut with precision
