Milwaukee Electric Tool 49-56-0173 Ice Hardened Bi-Metal Hole Saw Review

Milwaukee Electric Tool Corporation has revolutionized hole saws with their new line of Ice Hardened hole saws. These products utilize a proprietary cryogenic hardening process that improves upon traditional heat treat processes. Unlike surface coatings that wear away, cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (marten site). This creates a product that is consistently hard throughout, resulting in up to 50% longer life than the competition.

The Milwaukee Electric Tool 49-56-0173 Ice Hardened Bi-Metal Hole Saw, 3" Die, 8% Cobalt, features Matrix II bi-metal teeth for greater durability and a unique precision-ground tooth geometry for faster cutting. The positive rake angle cuts more aggressively, while deeper gullets quickly remove chips. The radiused back face reduces stress on the teeth, ensuring that the blade delivers optimum life and speed. Functional slot geometry allows for a standard slotted screwdriver to fit completely underneath the plug for easier plug removal.

This hole saw is perfect for cutting through a variety of materials, including mild steel, stainless steel, cast iron, and aluminum. In addition, it is ice hardened for up to 50% longer life than the competition. With its Matrix II bi-metal teeth and optimized tooth form, the Milwaukee Electric Tool 49-56-0173 Ice Hardened Bi-Metal Hole Saw is sure to make cutting tasks a breeze.
