- Step drills are ideal for drilling into the following materials: - Ferrous & non-ferrous sheets metals, profiles and pipes. - Copper, brass and aluminium. - Stainless steel. - Plastics. - Maximum material thickness 4 mm. - To ensure best lifetime we recommend the use of a coolant
- Trades: - Electrical: drilling of panels and cabinets for cable gland installation. - Plumbing / HVAC: access holes for pipework and installation. - Metal workers / fabrication: various sizes and hole enlargement. - Automotive: holes for cable installation (mobile telephones, antennas, re-directing electrical wiring). - Maintenance repair operations: various applications, sizes and hole enlargement
- Step Drill advantages over conventional drill bits: - One drill bit to drill multiple sizes - Do more carry less! - Best option for enlarging existing holes. - More durable than twist drill bits, thick core resists breakage. - More accurate and less walking, tip starts on contact. - Clean burr free holes, less reaming required. - Drills plastic without splitting or cracking
- Spot drill - Drill - Deburr - All in one go
- RAPID STRIKE TIP™: Accurate start without walking and fast drilling without the need to pre-drill the material
- Special tip and step geometry for jam-free performance - less risk of drill snagging when used with high speed cordless tools and also prevents deformation of the drilled material
- Optimised 2 flute ground sharpened edge geometry for 2 x faster and smoother cutting
- Produced from custom engineered steel with black oxide coating for 4 x longer life
- Optimised for use with high speed cordless drills
- Laser engraved size markings for best long term visibility
- Each step is relief ground to drill and deburr automatically
- With 3 flat secure grip to prevent step drill from slipping in the chuck and ensure maximum transmission of torque
- Shank diameter 8 mm
- Size 4 - 20 mm
- Number of steps 9
