DeWalt Reciprocating Saw Blade DW4807B 6 Inch 14 TPI Bi-Metal (100 Pack Straight Back Nail Embedded Wood Framing Demolition Cutting Universal Shank)

DeWalt DW4807B 4-Inch 14 TPI Bi-Metal Reciprocating Saw Blades (100-Pack Box)

The DeWalt DW4807B 4-Inch 14 TPI Bi-Metal Reciprocating Saw Blade Bulk Box is an industrial demolition cutting accessory engineered for high-speed plunges and crosscuts through nail-embedded wood, dimensional framing timber, PVC piping, and thin sheet metal. Manufactured with a flexible spring steel backing welded to a high-speed matrix steel tooth edge, this 100-blade contractor pack features a 1/2-inch universal shank that fits all standard reciprocating saw chucks. Formulated with a straight back profile, patented tooth geometry, an aggressive shank angle, and an anti-stick friction-reducing coating, these 14 TPI blades prevent binding and teeth shearing under heavy jobsite demolition loading.

Best Used For:

• Nail-Embedded Framing Demolition: Shearing through wall studding, floor joists, and window headers containing embedded steel framing nails and staples.
• Plumbing Pipe & Conduit Sizing: Slicing schedule 40 PVC water pipe, plastic drainage lines, and thin-wall electrical metallic tubing (EMT) cleanly.
• Remodeling & Wall Panel Cutouts: Executing plunge cuts and rough openings through plaster, plywood sheathing, exterior siding, and drywall.

Key Performance & Safety Features

• Bi-Metal Matrix Steel Construction: Combines a flexible alloy steel body with high-speed steel tooth tips to resist fatigue snapping and thermal wear.
• 14 TPI Patented Tooth Geometry: Medium tooth pitch balance speeds up cutting rates in wood while preventing tooth stripping on metal fasteners.
• Aggressive Shank Angle Profile: Maintains constant tooth engagement and fast cutting speeds as the blade wears during continuous use.
• Anti-Stick Friction Coating: Non-stick thermal barrier reduces heat buildup, pitch gumming, and drag inside deep wood cuts.
• Straight Back Body Architecture: Rigid straight back design provides control and stability for straight plunge cuts and flush wall trimming.
• 1/2-Inch Universal Tang Mount: Fits all major corded and cordless reciprocating saws, Sawzall tools, and compact reciprocating saws.

Pro-Tip: Press the reciprocating saw shoe firmly flat against the wood surface before triggering the motor; maintaining steady forward shoe contact prevents blade whipping and eliminates tooth shock when hitting hidden steel nails.
