Drill Hole Saw Milwaukee 49560024 Cutting Depth 4.1 cm Diameter 2 cm

The MILWAUKEE 49560024 drill hole saw provides precision cutting with a cutting depth of 41 mm and a diameter of 20 mm. Engineered with a 1.27 mm thick steel body and bi-metal construction, this holesaw combines rigid shape retention with some built-in elasticity for reliable performance across a wide range of materials.

Advantages

A variable 4–6 teeth per inch profile with a positive 10° tooth angle enables faster, more aggressive cutting while improved heat dispersion helps teeth stay sharper longer. Deeper curved gullets promote efficient chip clearance to prevent clogging and heat build-up. The specially shaped tooth angle reduces snagging on thinner materials, and alternate/side-set teeth minimise binding and friction, requiring less feed pressure. Matrix II premium high-speed steel (with 8% cobalt) is used for the toothed area and is laser-welded to a high-alloy steel body; the teeth are vacuum-hardened to 65 HRC for enhanced durability and wear resistance.

Suitable for

• Steel up to 1000 N/mm²
• Stainless steel and acid-resistant steels
• Non-ferrous metals and aluminium
• Cast iron
• Wood and medium density fibreboard (MDF)

How to use

Fit the holesaw to a compatible arbor and ensure correct engagement with the 4 drive pin holes. Use a drill (hand or pillar drill with manual feed) and align the pilot to the marked drilling point. Apply steady, moderate feed pressure—excessive force is unnecessary due to aggressive tooth geometry and efficient chip clearance. Maintain cutting speed appropriate for the material being cut and use cutting fluid when drilling metals to reduce heat and extend tool life. Remove the core using the diagonal slots if required.

Usage recommendations

For cutting metals such as stainless steel and high-strength steels, use a suitable cutting lubricant and moderate drilling speeds. For wood, plasterboard and plastics, higher speeds may be used but avoid overheating. Inspect the back plate and teeth regularly and replace the holesaw if the teeth show significant wear or damage.
