Dewalt Accessories DW4838 Bi-metal Reciprocating Blade 5 Pack

Product Description

The DEWALT ACCESSORIES DW4838 is a 12-inch bi-metal reciprocating blade engineered for metal cutting applications. Sold in a pack of 5, these blades run at 14 TPI (teeth per inch) with a straight-back profile that fits standard reciprocating saw chucks. The patented tooth geometry delivers faster cut rates compared to conventional designs, while an aggressive shank angle increases tooth contact across the full stroke. As the blade wears, that geometry helps maintain cutting speed, extending usable blade life. A specially formulated anti-stick coating reduces friction and minimizes gumming when cutting ferrous and non-ferrous metals.

These blades are suited for metal cutting tasks in commercial and industrial settings, as well as trade service work involving conduit, pipe, angle iron, sheet metal, and structural steel. The 12-inch length provides reach into deeper cuts and confined spaces where shorter blades lose access. HVAC technicians, plumbers, and electricians commonly use this blade length for cutting installed pipe and conduit during retrofit and service work. The 5-pack quantity supports ongoing jobsite use without frequent restocking.

Compatibility

Designed as an OEM-style replacement blade for standard reciprocating saws accepting universal shank bi-metal blades.

Installation Notes

Blade installation and changes should be performed with the tool unplugged or the battery pack removed. A licensed electrician, plumber, or HVAC technician should follow applicable trade codes when cutting energized-adjacent systems, and all utilities should be confirmed de-energized before cutting in those areas. Use appropriate eye protection and gloves when handling and changing blades.
