4" Standard Metal Blades, Double Duty, 14 TPI, 5 Pack

Milwaukee 48-00-5181 – 4" SAWZALL® Blades, 14 TPI, Metal Cutting (5-Pack)

The Milwaukee 48-00-5181 SAWZALL® reciprocating saw blades are engineered for controlled, high-efficiency cutting of thin metals. Each 4" blade features 14 teeth per inch (TPI), optimized for precision in materials such as sheet metal, conduit, and small-diameter tubing. Designed for compatibility with standard reciprocating saws, these blades deliver consistent results in metalworking, electrical, and mechanical applications.

This 5-pack includes blades constructed with bi-metal technology and Milwaukee's proprietary tooth design, offering increased wear resistance and reduced breakage risk under heavy use. A reinforced tang improves blade stability and minimizes failure during demanding cuts.

Application Notes

These blades are intended for use in reciprocating saws with standard blade mounts. They are suited for fast cuts in ferrous and non-ferrous metals up to 1/8" thick. Proper alignment and feed pressure are essential to maximize blade life. Use of cutting lubricant may improve performance and reduce tooth wear in extended cutting operations.

Jobsite Considerations

• Designed for service and installation professionals in electrical, HVAC, and mechanical trades
• Optimized for short-stroke saw applications and limited access spaces
• Not recommended for use on stainless steel or hardened alloys without specialized lubrication
