Milwaukee TiAlN SHOCKWAVE step drill set 3-piece set 4-12mm + 4-20m + 4-30mm

Step drills are ideal for drilling in the following materials: alloyed and unalloyed sheets, profiles, and pipes; copper, brass, and aluminum; stainless steel; plastic. The maximum material thickness is 4 mm. To increase tool life, the use of coolants is recommended.

Applications: Electricians: drilling plates and control cabinets for cable installations; HVAC: access holes for pipes and lines; metalworkers: drilling various diameters and enlarging holes; automotive: holes for cable installations (mobile phones, antennas, cable laying); maintenance: various applications, sizes, and hole enlargements.

Advantages of step drills over conventional drills: one drill for different diameters; optimal solution for enlarging holes; more break-resistant than metal drills; easy centering; clean and burr-free holes; splinter-free drilling in plastic.

Punching, drilling, and deburring in one step. Rapid Strike drill tip for easier centering, no wandering of the drill, and faster drilling progress without pre-drilling.

Special drill tip and unique step geometry enable chatter-free drilling. Reduced risk of binding or deforming the material being drilled at high speeds.

Optimized 2-spiral geometry with sharpened edges for up to 2x faster drilling progress. Made from special steel with a black oxide coating for up to 4x longer lifespan.

Optimized for use with cordless tools. Laser marking of diameters for long-lasting readability. Each step is back-ground for optimal drilling feed and automatic deburring. Shank with 3 clamping surfaces for secure grip in the chuck and optimal power transmission.
