Milwaukee Electric Tool 49-56-0197 Ice Hardened Bi-Metal Hole Saw, 3-5/8"

The Milwaukee 49-56-0197 is a 3-5/8 inch bi-metal hole saw engineered for clean, efficient boring. Designed for users who need consistent cutting performance, it addresses common frustrations like premature tooth wear and jammed material plugs during drilling operations.

Durability and cutting speed come from its specialized tooth and body engineering. The tool features Matrix II bi-metal teeth treated with an Ice Hardened process, which provides up to 50 percent longer life than competing models. A positive rake angle promotes faster material penetration, while a radiused tooth back reduces mechanical stress across each individual tooth during heavy cutting.

Clearing waste is straightforward thanks to deeper gullets that speed up chip removal. Additionally, the hole saw incorporates a plug jack alongside functional slot geometry, allowing users to pry out cut plugs quickly without wasting time fighting stuck debris inside the cup.

As a single-diameter tool, it is strictly built for 3-5/8 inch holes, so jobs requiring multiple diameters will need additional sizes. The listing also does not mention whether an arbor, pilot drill bit, or adapter is included, meaning you may need to supply your own mounting hardware.

Verdict: This hole saw is a reliable choice for anyone needing a durable, fast-cutting 3-5/8 inch cutter. It is ideal for tradespeople and DIYers looking for extended blade life and hassle-free plug removal.

A great fit if you:

• Need to cut precise 3-5/8 inch diameter holes
• Want a long-lasting bi-metal saw with hardened cutting teeth
• Value fast chip clearing and easy plug removal features

Consider something else if you:

• Require an all-in-one kit with assorted hole saw sizes
• Need an option that explicitly includes an arbor or pilot bit in the package
