Milwaukee 49-56-0043 Ice Hardened Hole Saw

The 49-56-0043 Ice Hardened Bi-Metal Hole Saw is a 1-inch cutting accessory designed for dependable boring through various materials. Built for users who need clean 1-inch holes without premature tooth wear, it combines treated cutting edges with smart body geometry to streamline drilling tasks.

Its construction relies on a proprietary cryogenic hardening process that improves upon traditional heat treating, offering up to 50 percent longer working life. Matrix II bi-metal teeth resist wear, while the positive rake angle aggressively cuts through material to speed up your workflow. A radiused tooth back further protects the blade by reducing mechanical stress on the cutting edges.

For everyday operation, the tool incorporates deep gullets to evacuate chips rapidly, preventing clogs mid-cut. Once a cut is complete, the functional slot geometry allows you to extract the leftover core easily without fighting jammed plugs. However, as a dedicated 1-inch unit, it will not cover tasks requiring other hole sizes, and the product details do not specify which arbors or pilot bits fit the saw.

Verdict: This 1-inch hole saw is an excellent pick for anyone needing a durable, fast-cutting blade made in the United States. Its hardened teeth and easy-eject slots make it a dependable choice for consistent hole cutting.

A great fit if you:

• Need to cut precise 1-inch diameter holes.
• Want cutting tools manufactured in the United States.
• Prefer bi-metal teeth hardened for extended service life.
