Drill Hole Saw Milwaukee 49560047 Cutting Depth 4.1 cm Diameter 2.7 cm

The Milwaukee 49560047 drill hole saw is a bi-metal holesaw with a cutting depth of 41 mm and a diameter of 27 mm designed for precision hole cutting in a wide range of materials. It features a variable 4–6 TPI tooth geometry with a positive 10° tooth angle and a 1.27 mm thick steel body to provide balance between rigidity and elasticity for stable cutting performance.

Advantages

The variable 4–6 teeth-per-inch design with a positive 10° angle enables faster, more aggressive cutting while improved heat dispersion helps the teeth stay sharper longer. Deeper curved gullets ensure efficient chip removal and reduce clogging and heat build-up. The specially shaped teeth reduce snagging on thinner materials and alternate/side set tooth configuration minimizes binding and friction, requiring less feed pressure. Teeth are made from Matrix II premium high-speed steel (8% cobalt) and laser-welded to a high-alloy steel body, then vacuum hardened to 65 HRC for high wear resistance and long life. A thick steel back plate preserves hole diameter over time, adds rigidity and reduces vibration, and includes four drive-pin holes for easier arbor alignment.

Suitable for

• Steel up to 1000 N/mm²

How to use

Fit the holesaw onto a compatible arbor and secure it to the drill. Align the pilot bit or arbor with the mark for the desired hole and start drilling at an appropriate speed for the material. Apply steady, moderate feed pressure — the aggressive tooth geometry and good chip clearance reduce the amount of force required. For deeper cuts or harder materials, use steady, controlled progress and withdraw occasionally to clear chips.

Usage recommendations

Use cutting lubricant or coolant when cutting stainless steel, acid-resistant steels or other hard metals to improve heat dissipation and prolong tooth life. Ensure the drill is held steady and use manual feed only with pillar drills to maintain precision and avoid overload.
