PG 7 – PG 21 – 1 pc – Step drills
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 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.
