Includes 3 SHOCKWAVE™ step drill bits: 4 - 12 mm/1, 4 - 20 mm, 4 - 30 mm

• Step drills are ideal for drilling into the following materials: - Ferrous and 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 for improved centering - less walking and fast drilling without the need to punch or 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.
