Step drill bits set Milwaukee Step Drill 4-35 mm 3 pcs (48899399)
Step drill bits set Milwaukee Step Drill 4-35 mm 3 pcs (48899399) includes three drill bits: 4-12 mm with a 1 mm step, 4-20 mm with a 2 mm step, and 6-35 mm with a 2 mm + 3 mm step. The drill bits are perfect for drilling black and non-ferrous sheet metal, profiles and pipes, copper, brass, aluminum, stainless steel, and plastic. The maximum material thickness is 4 mm. To increase the drill bit's lifespan, it is recommended to use a cooling fluid. Step drills are used for drilling in panels and cabinets to install cable glands, for drilling holes to access pipelines, for enlarging holes, and more. The RAPID STRIKE TIP™ ensures precise starts without wandering and quick drilling without the need for material pre-drilling. The RAPID STRIKE TIP™ quickly engages, eliminating the need for centering or pre-drilling the material. The optimized geometry with two flutes and sharp edges provides twice the speed and accuracy of cut. The special tip and step drill geometry reduce the risk of bit jamming when using high-speed cordless drills and protect the material from deformation. Each step of the drill has relief that automatically removes burrs. The tri-flat shank prevents the drill from slipping in the chuck and ensures maximum torque transfer. Laser-etched markings do not wear off over time.

Advantages of a step drill bit
The Rapid Strike tip ensures an accurate start without "walking" and enables fast drilling without the need for pre-drilling. Drilling, expanding, and countersinking—all in one.
