Compact 15-Piece General Purpose Hole Saw Kit

The Milwaukee 49-22-4175 General Purpose Hole Saw Kit, 15-Piece, introduced by the Milwaukee Electric Tool Corporation, is a new generation of hole saws designed to offer up to 50% longer life than the competition. These Ice Hardened hole saws are ideal for a wide range of applications, including metal and wood cutting in HVAC, electrical, plumbing, and maintenance/repair projects.

The key features of this innovative product include the use of a proprietary cryogenic hardening process that improves upon traditional heat treat processes. Unlike surface coatings that wear away, the cryogenic process hardens the core of the product, minimizing soft metal (austenite) and creating more hard metal (martensite). This results in a more consistently hard product, leading to a life expectancy up to 50% longer than the competition.

Moreover, the Milwaukee Ice Hardened hole saws feature Matrix II bi-metal construction for greater durability and a unique precision-ground tooth geometry for faster cutting. The positive rake angle cuts more aggressively, while the deeper gullets quickly remove chips. The radiused back face of the teeth reduces stress, ensuring the blade delivers optimum life and speed.

The kit includes eleven (11) hole saws ranging from 3/4" to 2-1/2" in diameter, two (2) arbors, two (2) drill bits, one (1) adapter, and one (1) spacer, providing a comprehensive solution for a variety of hole-cutting needs. The functional slot geometry allows for a standard slotted screwdriver to fit completely underneath the plug, making plug removal easier.

The Milwaukee 49-22-4175 General Purpose Hole Saw Kit is designed for ease of use, durability, and efficiency. Manufactured in the United States, this product is a testament to Milwaukee's commitment to innovation and quality, delivering a solution that can significantly extend the life of hole saws compared to the competition.
