Value Collection BD3121 Reciprocating Saw Blade 4in 18 Tpi

Product Description

The VALUE COLLECTION BD3121 is a bi-metal reciprocating saw blade designed for use with standard reciprocating and orbital reciprocating saws. At 4 inches in length with an 18 teeth-per-inch (TPI) constant pitch pattern, this blade is suited for controlled, fine-cutting tasks in wood, plastics, and light non-ferrous materials. The tapered profile and angled tip improve blade clearance during plunge cuts and tight-radius work. The universal shank fits the majority of reciprocating saw chucks without adapters. Installers working in HVAC, plumbing, and electrical trades will find this blade useful for trim-out and rough-in cutting tasks where precision over speed is the priority.

This blade is appropriate for residential and light commercial service work. The 18 TPI constant pitch is well matched to cutting plastic conduit, thin-wall copper tubing, ABS drain pipe, and finish wood in confined spaces. The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, reducing breakage during curved or angled cuts. It is sold individually, with a minimum order quantity of 5 units per order.

Key Features

• Bi-metal construction for extended cutting life and reduced blade breakage
• 4-inch blade length suitable for confined-space and trim-out applications
• 18 TPI constant pitch for smooth, controlled cuts in plastic, copper, and light wood
• Tapered profile with angled tip improves plunge-cut entry and tight-space maneuverability
• Universal shank compatible with standard reciprocating saw chucks
• 0.035-inch blade thickness provides a balance of rigidity and flex

Compatibility

Designed for use with reciprocating saws equipped with a universal shank chuck, which covers the majority of corded and cordless reciprocating saw models on the market.

Installation Notes

Always ensure the reciprocating saw is powered off and the battery is removed or the tool is unplugged before changing blades. Secure the blade fully in the chuck before operation and verify the locking mechanism is engaged. Wear appropriate eye protection and gloves when handling saw blades, as cutting edges and the angled tip present laceration hazards. Follow applicable jobsite safety codes when cutting near electrical wiring, gas lines, or plumbing.
