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. MILWAUKEE Advantages 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.

The drill bit is ideal for deburring, drilling round holes and enlarging existing holes. Pre-punching is unnecessary as the split tip allows easy drilling. The CNC ground spiral groove offers optimised chip removal and reduced vibration for uniform drilling. Axial and radial back grinding ensure excellent cutting performance and absolute smoothness. This step drill is suitable for use on thin materials, such as non-ferrous metals, sheet plastic, sheet steel, plastic and stainless steel. The step drill is made of HSS (High-Speed Steel) and will last a long time if coolant is used. Using laser, the hole diameters in both spiral grooves are clearly visible and durably marked. In addition, the 3-surface shank prevents slipping in the chuck and ensures high torque transfer. 3-surface shank for drills.
