Milwaukee step drill and metal drill bit set

Product information
• Step drills are ideal for drilling in the following materials: - Alloyed and unalloyed sheet metal, profiles and pipes. - Copper, brass and aluminium. - Stainless steel. - Plastic. - Maximum material thickness 4 mm. - The use of coolants is recommended to increase tool life
• Trades: - Electricians: Drilling panels and switch cabinets for cable installations. - HVAC: Access holes for pipes and cables. - Metalworkers: Drilling different diameters and enlarging holes. - Automotive: holes for cable installations (mobile phones, antennas, laying cables). - Maintenance: various applications, sizes and hole enlargements
• Advantage of step drills over conventional drills: - One drill for different diameters. - Optimal solution for enlarging drill holes. - More break-proof than metal drills. - Easy centring. - Cleaner and burr-free holes. Splinter-free drilling in plastic
• Punching, drilling and deburring in one step
• Rapid Strike drill tip for easier centring - no inch-wandering of the drill bit and fast drilling progress, without pre-drilling
• Special drill tip and special step geometry enable chatter-free drilling. Reduced risk, risk of jamming at high speeds or deforming the material being drilled
• Optimised 2-spiralgeometry with sharpened edges for up to 2x faster drilling progress
• Made from special steel with black oxide coating for up to 4x longer service life
• Optimised for use with battery-powered tools
• Laser marking of the diameter for long-lasting legibility
• Each step is relief-ground for optimum drill feed and automatic deburring
• Shaft with 3 clamping surfaces for secure hold in the drill chuck and optimum power transmission
