Step Drills

• Step drills are ideal for drilling in the following materials: - Sheets of ferrous and non-ferrous metals, profiles, and pipes. - Copper, brass, and aluminium. - Stainless steel. - Plastics. - Maximum material thickness is 4 mm. We recommend using coolant.
• Applications: - Electrical: drilling in panels and cabinets for connector installation. - Hydraulic, heating, air conditioning, and ventilation: inspection holes. - Machining/production: various diameters and enlarging holes. - Automotive industry: holes for cable installations (mobile phones, antennas, wiring). - Maintenance and repair activities: various applications, enlarging holes.
• Advantages of step drills compared to traditional drills: - One drill makes holes of different diameters - More possibilities, less wear! - The best way to enlarge an existing hole. - The core is untwisted and thicker, thus less prone to breakage. - More accurate hole positioning as the tip drills immediately. - Burr-free holes, no need for a reamer. - Drilling in plastic without cracking.
• Advantages of Milwaukee®
• Punching, drilling, smoothing - all in one.
• The Rapid Strike tip improves centring - less lateral movement of the drill and fast drilling without the need for a centre punch or pre-drilling.
• Special tip and stepped geometry to prevent jamming - especially when using high-speed, cordless tools - and material deformation.
• 2 optimised cutting edges allow for 2x faster and smoother cutting.
• Made from specially selected steel with an oxidised surface, making the tool 4 times more durable.
• Optimised for use with high-speed cordless drills.
• Laser-engraved, durable, and legible markings.
• Each step is ground so that the drill automatically smooths the edges during drilling.
• The 3-Flat Secure Grip shank provides better tool grip in the chuck and ensures maximum torque transfer.
