Milwaukee Step Drill Bit 4 - 20mm - Pack fo 1

Technical data:
Clamping: 8 mm
Total length: 65 mm
Number of steps: 9

Step drills are ideal for drilling the following materials:
- Ferrous and non-ferrous plates, profiles and pipes.
- Copper, copper and aluminum.
- Stainless steel.
- Plastics.
- Maximum material thickness: 4 mm
- We recommend the use of coolant to maintain the life of the tool.

Application:
- Electrical installation: drilling for the installation of glands in panels and cabinets.
- Plumbing, heating, air conditioning and ventilation: installation openings for piping operations and installation.
- Metalworking / manufacturing: design and widening of holes of different diameters.
- Automotive industry: cable mounting holes (mobile phones, antennas, cable entry).
- Maintenance and refurbishment activities: expansion of various applications, sizes and holes.

Advantages of step drills over conventional drills:
- A drill can drill holes of several diameters.
- More options, less walking!
- The best way to widen existing holes.
- More accurate than augers and less prone to breakage due to its thick core.
- More precise positioning and less displacement because the centering tip integrated in the drill bit starts drilling immediately.
- The openings are free of burrs, less
drilling is required - There are no cracks when drilling plastic.

Benefits of Milwaukee
Point drilling, drilling, deburring - all in one.
- Rapid Strike Center Drill improves centering - less lateral movement of the drill and faster without the need to drill, punch or use a pre-drill.
- Special drill bit and stepped geometry to prevent jamming and material deformation - especially when using high-speed cordless tools.
- Optimized, sharp-edged chip grooves allow for twice as fast and even cutting.
- Made of uniquely structured steel with a black oxidized surface, which increases the tool life by a factor of 4.
- Optimized for use with high speed cordless drills.
- Laser engraved, durable and legible marking.
- All steps are turned so that the drill automatically deburrs the edges during drilling.
- The 3-sided Secure Grip chuck prevents the drill bit from slipping out of the chuck and ensures maximum torque transmission.
