The Milwaukee 49-56-0158 hole saw is an innovative tool with several unique features. This hole saw has Matrix II bi-metal construction for greater durability and a unique precision-ground tooth geometry for faster cutting. A positive rake angle cuts more aggressively while deeper gullets quickly remove chips. A 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. To improve the life of this hole saw, Milwaukee Electric Tool Corporation uses a proprietary cryogenic hardening process. Unlike surface coatings that wear away, cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (martensite). This process is responsible for the Ice Hardened feature that extends the life of the hole saw by up to 50% compared to other hole saws in its class.
