Step Drill Bit Milwaukee PG7-PG21

The step drill bit is well suited 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 cooling fluid.

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

Advantages of a step drill bit over a regular drill bit:
One drill bit can drill holes of different sizes — less to carry around!
The best option for enlarging existing holes.
More durable than spiral drills, a thick core protects against breakage.
Greater accuracy and less slippage, the tip stays in contact.
Clean holes without burrs, less need for grinding.
Drills plastic without causing splits or cracks.

Starting point drilling, drilling, burr removal — all at once.
A quick impact 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 transfer.
