Dewalt DWA4188B 8in 14 Tpi Demolition Reciprocating Blade 25pk

Product Description

The DEWALT DWA4188B is a bi-metal reciprocating saw blade engineered for heavy demolition work. Built with a high-speed steel tooth edge bonded to a flexible alloy steel body, this blade handles the abuse of tearing through mixed materials, embedded fasteners, and structural assemblies without snapping. At 8 inches in length with a 14 TPI tooth count, it is optimized for fast, aggressive cuts through wood with nails, light steel framing, conduit, and similar demo materials. Sold in a bulk pack of 25 blades, this configuration suits contractors and service crews who run through blades at volume on active job sites.

This blade is designed for demolition and remodeling applications where cutting speed and blade durability matter more than finish quality. Typical use cases include structural tear-outs, framing removal, pipe cutting, and rough rough-in work on residential and light commercial job sites. The 14 TPI geometry provides a balance between cutting aggression and chip clearance, making it practical across a range of demo scenarios rather than specialized for a single material type.

Key Features

• Bi-metal construction — high-speed steel teeth on a flexible alloy steel body for durability under demolition stress
• 8-inch blade length provides reach for deep cuts in structural and pipe applications
• 14 TPI tooth geometry balances cutting speed and chip clearance across mixed materials
• Rated for demolition duty — handles wood with embedded nails, light steel, and conduit
• Bulk pack of 25 blades reduces per-blade cost for high-volume crews and contractors

Compatibility

Designed as an OEM-style replacement blade compatible with standard reciprocating saw tool chucks accepting universal shank reciprocating saw blades.

Installation Notes

Reciprocating saw blade changes should be performed with the tool powered off and the battery or power cord disconnected. Use the tool's blade clamp or key mechanism as specified by the saw manufacturer — never force a blade into a chuck. Inspect blades before each use and discard any blade showing cracks, missing teeth, or visible deformation. Eye protection and cut-resistant gloves are standard PPE for demolition cutting operations.
