Hole Saw Milwaukee 49560142 6 cm Diameter 4.1 cm Cutting Depth

The Milwaukee 49560142 hole saw with a 6 cm diameter and 4.1 cm cutting depth uses advanced bi-metal construction and a Matrix II high-speed steel tooth material for durable, precise cutting across a wide range of materials. A variable tooth pitch (4–6 TPI) with a positive 10° tooth angle, deeper curved gullets and alternate/side-set teeth provide faster cutting, improved chip clearance and reduced tendency to snag. The 1.27 mm thick steel body preserves shape while allowing some elasticity, and the 41 mm effective sawing depth suits many standard drilling tasks. A robust back plate with four drive-pin holes and diagonal slots facilitates arbor location and core ejection.

Advantages

Variable 4–6 teeth per inch and a 10° positive tooth angle deliver an aggressive, faster cut with reduced feed pressure. Matrix II high-speed steel teeth (with cobalt) retain hardness at high temperatures for longer life when cutting metals. Bi-metal laser-welded construction and vacuum hardening to 65 HRC increase durability. The thick steel back plate maintains hole accuracy and reduces vibration, while diagonal slots and drive-pin holes simplify core removal and arbor alignment.

Suitable for

• Cutting steel up to 1000 N/mm²

How to use

Fit the holesaw to a compatible arbor and secure it to the drill using the drive pins as required. Use manual feed only — the product is suitable for hand and pillar drills with manual advancing. Start drilling at low speed to establish the cut, then increase speed and apply steady, moderate feed pressure. Clear chips periodically to maintain chip clearance and reduce heat buildup; diagonal slots assist in core ejection when the cut is complete.

Usage recommendations

For best performance when cutting metals, use cutting lubricant and moderate feed pressure. When working with wood or softer materials, ensure correct pilot drill alignment and remove the core promptly to avoid binding.
