Step Drill Bit Milwaukee 6-40.5 mm

This step drill bit is ideal for drilling the following materials: - iron and non-iron metal sheets, profiles, and pipes; - copper, brass, and aluminum; - stainless steel; - plastic. - The material thickness can be up to 4 mm.
For longer service life, we recommend using a coolant.

Applications: - Electrical work: drilling panels and cabinets for cable gland installation. - Pipe and ventilation work: access holes for piping and installations. - Metalwork/manufacturing: holes of various sizes and enlarging holes. - Automotive industry: installation holes for cables (mobile phones, antennas, electrical wire relocation). - Maintenance and repair: various tasks, holes of different sizes, and enlarging holes.

Advantages of a step drill bit over a regular drill bit:
A single drill bit can drill holes of different sizes — less to carry!
The best option for enlarging existing holes.
More durable than twist drills, a thick core protects against breakage.
Greater precision and less slippage, the tip stays at the contact point.
Holes without burrs, less need for grinding.
Drills plastic without creating splits or cracks.

Starting point drilling, drilling, burr removal — all at once.
A quick-strike tip improves centering: less slippage and faster drilling without pre-punching or drilling.
The special shape of the tip and steps prevents jamming: less risk of the drill bit getting stuck when using a fast cordless drill; also prevents deformation of the material being drilled.
The optimized shape of the two ground cutting edges ensures 2x faster and smoother cutting.
Made from a special steel alloy, the black oxide coating ensures 4x longer service life.
Optimized for use with fast cordless drills.
Laser-engraved size marking ensures the best long-term visibility.
Each step is ground in relief to allow automatic drilling and burr removal.
Three-flat secure attachment prevents the step drill bit from slipping in the chuck and ensures maximum torque transmission.
