Milwaukee 48-42-5390 Heavy Duty Jig Saw Blade 12 Tpi Bi-metal

Product Description

The MILWAUKEE 48-42-5390 is a heavy duty bi-metal T-shank jig saw blade sold in a 5-pack, designed for cutting metal and nail-embedded wood. At 3 inches in length and 3/16 inches in width, the blade features a 12 TPI milled and wavy tooth configuration that delivers fast, clean cuts while minimizing vibration. The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, giving the blade significantly more impact resistance and longevity than standard high-speed steel or carbon blades. The T-shank design allows for fast, tool-free blade changes on T-shank compatible jig saws. Licensed trade professionals and skilled DIYers working in metal fabrication, rough carpentry, and remodeling applications will find these blades well-suited for demanding jobsite conditions.

These blades are intended for use in T-shank jig saws across residential, commercial, and light industrial settings. Typical applications include cutting through metal pipe, sheet metal, dimensional lumber, and reclaimed or nail-embedded wood. Compatible models named in product documentation include Milwaukee jig saw models 6266-6, 6276-6, 6267-20, and 6267-21, as well as other popular T-shank jig saw brands. The 12 TPI count makes these blades well-suited for cutting metal where a moderate tooth pitch balances cut speed with surface finish quality.

Installation Notes

Installation and blade changes should be performed by a qualified tradesperson with the jig saw unplugged or battery removed before handling the blade. T-shank blades seat into the blade clamp without tools on most modern jig saws; confirm the blade is fully locked before operation. Wear cut-resistant gloves when handling bare blades, as teeth remain sharp even before first use. Follow all applicable tool manufacturer safety guidelines and applicable OSHA standards for power tool operation on the jobsite.
