Milwaukee 48-42-5310 4in 10TPI Bi-metal Jigsaw Blades 5 Pack

Product Description

The Milwaukee Electric Tool Corp 48-42-5310 is a 5-pack of 4-inch bi-metal jigsaw blades engineered for cutting a wide range of materials on the job site. Each blade measures 4 inches in length and features a 10 TPI (teeth per inch) configuration, making it well-suited for general-purpose cuts through wood, metal, and plastic. The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, which helps resist blade breakage under demanding conditions. The T-shank design provides a secure, tool-free connection to compatible jig saws. These blades are typically selected by electricians, plumbers, HVAC techs, and general contractors who need a reliable multi-material cutting solution.

These blades are appropriate for both residential and light commercial applications where versatility across materials is required. Common use cases include cutting pipe access holes, trimming plastic conduit, rough-cutting dimensional lumber, and working through thin-gauge sheet metal. The 10 TPI tooth geometry strikes a balance between cutting speed and surface finish, making it practical for a range of field tasks rather than fine finish work. The pack quantity of 5 blades supports extended use on multi-trade service calls or renovation projects.

Key Features

• Bi-metal construction for extended blade life and resistance to breakage
• 4 inches blade length for standard jigsaw reach and clearance
• 10 TPI tooth configuration for multi-material general-purpose cutting
• T-shank mount fits most modern jig saws with tool-free blade changes

Compatibility

Designed as an OEM-style T-shank replacement blade compatible with most jig saws that accept the standard T-shank blade interface.

Installation Notes

Blade installation and removal should always be performed with the tool unplugged or the battery removed to prevent accidental activation. Insert the T-shank fully into the blade clamp until it seats and locks before beginning any cut. Inspect each blade for cracks or dull teeth before use and replace immediately if damage is found. Blade selection and cutting technique should comply with applicable safety standards and the tool manufacturer guidelines.
