Milwaukee 49-56-0213 4-Inch Ice Hardened Hole Saw – Durable Bi-Metal, Fast Cutting

Overview

The Milwaukee 49-56-0213 4-Inch Ice Hardened Hole Saw is built for metal and wood cutting on a wide range of trades, from HVAC to electrical and plumbing. Made in the USA, this saw blends cryogenic hardening with Matrix II bi-metal teeth to deliver a consistent edge and reliable performance across jobsite conditions.

Key advantages

• Ice Hardened durability offers up to 50% longer life than many competitors, ideal for repeated holes in tough materials.
• Matrix II bi-metal teeth provide rugged cutting action and extended wear resistance for demanding applications.
• Positive rake angle and deeper gullets support fast, aggressive cuts and efficient chip removal.
• Radiused back reduces stress on teeth, helping sustain performance over time.
• 8% cobalt alloy adds wear resistance to the cutting edge for longer life in metal work.
• Functional slot geometry enables easy plug removal, supported by the Plug Jack design for access at varying material thicknesses.
• Rip Guard tooth form is described as the strongest in the industry, backed by a limited lifetime tooth break.

Design and compatibility

• Universal clutch with arbors supports fast, tool-free changes using Milwaukee quick-change arbors.
• Generic arbor compatibility works with popular arbors listed by Milwaukee (e.g., 49-56-7240, 49-56-7250, 49-56-9100, 49-56-7055, 49-56-7040, 49-56-7140, 49-56-7150).
• Bi-metal construction plus 8% cobalt delivers strong edge retention for metal and wood cutting alike.

Real-world use

On the job, technicians appreciate the 4-inch size for common panel and metal work, while the Plug Jack design reduces downtime when removing plugs. The combination of ice hardening, cobalt alloy, and precise tooth geometry helps sustain steady performance through a range of materials and thicknesses.

Use cases span HVAC installations, electrical access holes, plumbing work, and maintenance tasks where clean, accurate holes are essential. While outcomes depend on material and technique, this hole saw is positioned to offer durable performance and reliable holes over multiple projects.

Made in the USA

Designed for professionals who value American manufacturing quality, this hole saw is part of Milwaukee’s Ice Hardened lineup, built to deliver consistent results with strong edge retention and reliable cutting behavior.
