Milwaukee 49-56-0213 4-Inch Ice Hardened Hole Saw | Durable Bi-Metal Cutting

Overview

The Milwaukee 4-inch Ice Hardened Hole Saw 49-56-0213 is built to tackle metal and wood with precision. Made in the USA, it blends rugged toughness with thoughtful design for demanding jobs in HVAC, electrical, plumbing, and maintenance. Ice Hardened technology uses a cryogenic hardening process that hardens the core for longer life and more consistent performance.

Longer life and tougher teeth

Ice hardened to the core, this hole saw aims to last longer than standard tools. The Matrix II bi-metal teeth deliver durability and faster cutting, aided by a positive rake angle and deeper chip gullets. The 8% cobalt content enhances wear resistance for tougher materials.

• Core hardening protects cutting edges during heavy use
• Bi-metal construction improves durability and heat resistance
• Positive rake angle promotes fast cutting
• Radiused back reduces stress on teeth
• Deeper gullets enable swift chip removal and cleaner holes

Design features that boost on the job performance

The hole saw includes Rip Guard to minimize tooth breaks and a Plug Jack that allows full access during plug removal. The slot geometry enables easy plug access whether cutting thick or thin material, reducing downtime between holes.

• Rip Guard design helps prevent tooth breaks
• Plug Jack enables easier plug removal in tight spaces
• Universal quick-change arbors enable fast tool changes
• Broad arbour compatibility for flexible setups

Real world use and compatibility

This 4-inch hole saw is suited for HVAC, plumbing, electrical, and general metal or wood cutting. It works with arbors including 49-56-7240, 49-56-7250, 49-56-9100, 49-56-7055, 49-56-7040, 49-56-7140, and 49-56-7150, supporting quick swaps and reliable performance on the job site.
