Drill bit / Hole saw HEX, aluminium / metal / steel - 3 pcs, 48899399

Includes 3 step drills: 4-12 mm/1.4-20 mm, 6-35 mm

 

Step drills are ideal for drilling in the following materials:

• Sheets of ferrous and non-ferrous metals, profiles and pipes.
• Copper, brass and aluminium.
• Stainless steel.
• Plastics.
• Maximum material thickness is 4 mm.

 

We recommend using coolant.

 

Applications:

• Electrical: drilling in panels and cabinets for connector installation.
• Hydraulic, heating, air conditioning and ventilation: inspection holes.
• Machining/production: various diameters and enlarging holes.
• Automotive industry: holes for cable installations (mobile phones, antennas, wiring).
• Maintenance and repair activities: various applications, enlarging holes.

 

Advantages of step drills compared to traditional drills:

• One drill makes holes of different diameters
• More possibilities, less to carry!
• The best way to enlarge an existing hole.
• The core is untwisted and thicker, thus less prone to breakage.
• More accurate hole positioning, as the tip drills immediately.
• Burr-free holes, no reamer needed.
• Drilling in plastic without cracking.

 

Milwaukee® advantages

• Punching, drilling, smoothing - all in one.
• Rapid Strike tip improves centring - less lateral drill movement and fast drilling without the need for a punch or pre-drilling.
• Special tip and stepped geometry to prevent jamming - especially when using high-speed, cordless tools - and material deformation.
• 2 optimised cutting edges allow for 2x faster and smoother cutting.
• Made from specially selected steel with an oxidised surface, which makes the tool 4 times more durable.
• Optimised for use with high-speed cordless drills.
• Laser-engraved, durable and legible markings.
• Each step is ground so that the drill automatically smooths the edges during drilling.
• 3-Flat Secure Grip shank provides better tool grip in the chuck and ensures maximum torque transfer.
