Step drill 4-12 mm/1˝ Milwaukee /48899301/

• Step drill bits are ideal for drilling in the following materials: - Ferrous & non-ferrous sheet metal, profiles and tubes. - Copper, brass and aluminium. - Stainless steel. - Plastic. - Maximum material thickness 4 mm . - To ensure optimum tool life we recommend the use of a coolant.
• Applications in the following fields: - Electrical: drilling of plates and switchboards for cable grommet installation - Plumbing/HVAC: access holes for pipes and installations - Metal workers/factories: various drilling sizes and diameters - Automotive: holes for cable installation (mobile phones, antennas, power line rerouting) - Maintenance repairs: various applications, drilling sizes and diameters.
• Advantages of the step drill over conventional drill bits: - One drill bit for drilling multiple sizes - Do more, worry-free! - Best choice for enlarging existing holes - More durable than twisted drill bits, thick core prevents breakage - Less reaming required - Drills plastic without cracking or tearing.
• MILWAUKEE® Benefits
• Spot drill - Drill bit - Deburrer - all in one
• RAPID STRIKE™: for better centring - less wandering and fast drilling without the need to pre-drill the material.
• Special tip and geometry for jam-free performance - when using high-speed cordless tools, there is less risk of the drill bit jamming, preventing deformation of the drilled material.
• Optimised sharpened edges for 2x faster and smoother drilling.
• It is made from custom fabricated steel with a surface coating for 4x longer life.
• Optimized for use with high-speed cordless drills.
• Laser engraved marking: for long-term visibility.
• Each step automatically removes burrs and protects against overloading.
• Shank with 3 flat edges to prevent the drill bit from coming out of the chuck and to ensure maximum torque transmission.
