DEWALT DW4838 6-Inch 14 TPI Bi-Metal Reciprocating Saw Blades for Metal Cutting — Bundle of 4 Packs, 20 Blades Total

Product Description

This contractor bundle includes four factory 5-packs of DEWALT DW4838 reciprocating saw blades, providing a total of 20 blades.

Each blade measures 6 inches long and features a 14-teeth-per-inch configuration designed for efficient cutting through metal and other compatible materials.

The 14 TPI tooth pattern offers a practical balance between cutting speed and control, making these blades suitable for many medium-gauge metal-cutting applications. The straight-back profile provides stability during cutting, while the bi-metal construction combines a flexible blade body with a durable cutting edge.

This four-pack bundle is ideal for garage door installers, metal fabricators, maintenance departments, repair shops, contractors, and frequent users who need a dependable supply of replacement blades.

Recommended Applications

These blades are commonly used for cutting:

• Steel tubing
• Metal pipe
• Electrical conduit
• Garage door tracks
• Garage door angle and brackets
• Steel straps
• Threaded rod
• Metal framing
• Light structural steel
• Medium-gauge sheet metal
• Fasteners and bolts
• Other compatible metal materials

The 14 TPI configuration is generally suitable for medium-thickness metal where a balance of cutting speed and control is needed.

For very thin sheet metal, a finer 18 or 24 TPI blade may provide smoother cutting and reduce snagging. For thick metal or demolition work, a lower tooth count or specialty blade may be more appropriate.

Bi-Metal Construction

Bi-metal construction combines a flexible alloy-steel blade body with a hardened cutting edge.

The flexible backing helps the blade withstand vibration, bending, and demanding jobsite conditions, while the hardened teeth provide improved wear resistance during metal-cutting applications.

This construction generally provides greater flexibility and durability than basic carbon-steel blades when cutting metal.

Straight-Back Blade Design

The straight-back blade profile provides consistent support along the length of the blade.

This design is well suited for straight cuts through metal pipe, tubing, conduit, brackets, track, and other materials where control and blade stability are important.

For plunge-cutting applications, a taper-back or specially designed plunge-cutting blade may be more appropriate.

Compatibility

These blades are designed for reciprocating saws that accept standard universal-shank reciprocating saw blades.

They may be used with compatible saws from:

• DEWALT
• Milwaukee
• Makita
• Bosch
• RIDGID
• Metabo HPT
• Craftsman
• Porter-Cable
• Other manufacturers using a standard reciprocating-saw blade connection

Always verify the saw manufacturer’s blade requirements before installation.

Selecting the Correct Blade

Choose the blade according to the material type and thickness.

Several blade teeth should remain in contact with the material throughout the cut. Using a tooth count that is too coarse for thin metal can cause snagging, vibration, rough cuts, or damage to the material.

A 14 TPI blade is commonly selected for medium-gauge metal and general-purpose metal-cutting applications.

Consider using:

• 18 or 24 TPI blades for thinner metal
• Lower-TPI blades for thicker metal
• Variable-TPI blades for mixed material thicknesses
• Carbide blades for hardened, abrasive, or extremely demanding materials

Package Contents

• Four DEWALT DW4838 factory packs
• Five blades per factory pack
• 20 reciprocating saw blades total

The reciprocating saw, batteries, charger, storage case, cutting lubricant, and other accessories are not included.

Operating Tips

• Secure the workpiece before cutting
• Confirm that the blade is suitable for the material thickness
• Insert the blade fully into the saw’s blade clamp
• Keep the saw shoe firmly against the workpiece when possible
• Begin the cut at a controlled speed
• Allow the teeth to perform the cutting
• Avoid excessive pressure that may bend or overheat the blade
• Use appropriate cutting lubricant when recommended
• Replace blades that are bent, cracked, dull, or missing teeth

Excessive cutting pressure may increase heat, reduce cutting performance, and shorten blade life.

Safety Information

Disconnect the saw from electrical power or remove its battery before installing, removing, or inspecting the blade.

Wear appropriate eye protection, gloves, hearing protection, and any other personal protective equipment required for the work environment.

Recently used blades and freshly cut metal may be extremely hot or sharp. Allow the blade to cool before handling it.

Inspect the cutting area for concealed electrical wiring, plumbing, gas lines, pressurized lines, and other hazards before beginning work.
