Milwaukee Cobalt Bi-Metal Holesaw Kit

For Plumbers and Electricians

A variable 4/6 teeth per inch tooth design with a positive 10° tooth angle provides the following benefits:

• Faster and more aggressive cut.
• Improved heat dispersion during cutting ensures the teeth stay sharp longer.
• Depper curved gullets provide more efficient chip clearance preventing clogging and heat build up.
• Special shaped tooth angle has less tendency to snag on thinner materials.
• Teeth are alternate/side set to minimise binding and friction.
• Low feed pressure - This is achieved by the combination of aggressive tooth geometry and good chip clearance resulting in the requirement of less force during drilling

Type M42 premium high speed steel is used for the toothed area of the holesaw. M42 steel contains 8% cobalt resulting in the teeth retaining the original tooth hardness even at high working temperatures when used in metal cutting applications. Bi-Metal construction - High speed steel teeth are laser welded onto a high alloy steel body. The teeth are then vacuum hardened to 65 HRC at a temperature of 600°C to give maximum durability and lifetime. Due to the high wear resistance of the M42 material, these holesaws are ideal for cutting diffficult and hard materials such as stainless steel and acid resistant steels as well as softer materials like wood.

1.27mm thick steel holesaw body is rigid to retain its shape but also with built in elasticity. Effective sawing depth is a full 38mm over the complete range.

The back plates are constructed with 5mm thick steel thus the holes will not enlarge over the time. Thick backs add strength and rigidity minimising vibrations. 4 drive pin holes for easier arbor location. Perfectly manufactured round back plate for good concentricity, especially important for the larger diameter holesaws.

Diagonal slots aid in the removal and ejection of the core
