Dewalt DW4838 Bi-metal Reciprocating Saw Blade 12in 14TPI 5pk

Product Description

The DEWALT DW4838 is a 12-inch, 14 TPI bi-metal reciprocating saw blade designed for demanding cutting applications in the trades. The bi-metal construction pairs a high-speed steel tooth edge with a flexible alloy steel body, allowing the blade to resist breakage under the lateral stress common in demolition and rough-cut work. The straight-back profile ensures consistent tracking in standard reciprocating saw chucks. These blades are sold as a 5-pack, making them a practical stock item for any service van or job site. Tradespeople in plumbing, electrical, HVAC, and general construction rely on this blade length and tooth count for cutting through dimensional lumber, light metal, and mixed-material assemblies.

The 14 TPI tooth configuration on the DW4838 is suited for cuts where a balance of speed and surface finish is required. The 12-inch length provides reach for cutting in deeper or more restricted spaces than shorter blade lengths allow, such as cutting existing pipe, conduit, or structural members during renovation or demo work. This blade is a standard choice for plumbers cutting supply and drain lines, HVAC techs removing ductwork supports, and electricians working through framing during rough-in.

Key Features

• 12-inch blade length for extended reach in deep or restricted cuts
• 14 TPI tooth count balances cutting speed with cut quality
• Bi-metal construction combines high-speed steel teeth with a flexible alloy body for durability
• Straight-back profile for reliable chuck seating and consistent blade tracking
• 5-pack quantity reduces per-blade cost and supports job site stocking

Compatibility

Designed as a standard-shank replacement reciprocating saw blade compatible with reciprocating saws that accept universal T-shank or straight-shank bi-metal blades in the 12-inch class.

Installation Notes

Blade installation and changes should be performed with the saw unplugged or the battery pack removed. Secure the blade fully in the chuck before operating to prevent ejection during use. Wear appropriate eye and hand protection when cutting, as bi-metal blades generate metal chips and debris. Blade replacement is a standard task for any trade professional using a reciprocating saw on the job.
