50 Pack 6 in 14/18 TPI Reciprocating Saw Blade Set - Metal Cutting

Our review of this 50 pack of 6 in reciprocating saw blades finds it useful for contractors, fabricators, and DIYers who need a bulk supply for medium-thickness metal work. The single biggest reason to buy is value: the set pairs M42 teeth with 8% cobalt and a D6A blade body into an affordable 50-pack that fits common Sawzall-style tools and lets users replace blades frequently without hunting for a specific OEM item. For jobs that involve pipes, vehicle bodies or steel sheets around 0.1 to 0.125 in thick, these blades handle the cuts reliably while kept in a convenient plastic storage box.

Key Features

• Pack size: Fifty 6 in blades provide an economical supply for repeated metal cutting tasks, reducing trips to reorder blades.
• Material mix: M42 teeth with 8% cobalt and a D6A blade body balance hardness and toughness for cutting through nails, studs and medium metals.
• Cutting range: Optimized for medium-thick metal sheets from 0.1 to 0.125 in, making them suitable for steel, stainless, cast iron and pipes.
• Universal shank: A 1/2 in shank fits mainstream reciprocating saws such as Dewalt, Bosch, Milwaukee, Makita and others for broad compatibility.
• Durability enhancements: A new heat treatment process and UV coating aim to increase wear and heat resistance, reducing sudden breakage under demanding cuts.
• Packaging: Comes in a UV-coated plastic storage box for easy access and organized transport to the jobsite.

Who It's For

These blades suit professional tradespeople and serious DIYers who need a steady supply of metal-cutting blades and use reciprocating saws regularly. The 50-pack is ideal for demolition, auto body work, plumbing and general metal cutting where frequent blade changes are expected.

Those who prioritize extreme longevity or heavy industrial continuous cutting may want a higher-end branded blade with thicker body stock; similarly, if most of your work is wood cutting or fine finish cuts, a blade specifically designed for wood would be a better choice.

Pros & Cons

Pros

• Good value for bulk purchases, offering fifty blades in a single convenient box.
• M42 teeth with cobalt deliver strong cutting ability through nails, studs and moderate-thickness metal.
• Universal 1/2 in shank fits most common Sawzall-style tools for immediate use.
• Improved heat treatment and UV coating help extend service life under normal jobsite conditions.

Cons

• Some users report mixed durability; blades are relatively thin at 0.037 in and may wear or bend sooner than heavier-duty alternatives.
• Not optimized for extended heavy industrial use or precision woodwork where specialized blades perform better.

Frequently Asked Questions

Will these blades fit my reciprocating saw?
Yes, the 1/2 in universal shank is compatible with most Sawzall-style reciprocating saws from major brands.

What thickness of metal can these blades cut?
They are designed for medium-thick metal sheets roughly 0.1 to 0.125 in (about 3 mm) and work well on steel, stainless, pipes and vehicle bodies.

Are these blades durable for repeated use?
The blades include an improved heat treatment and UV coating to extend life, but customers note mixed durability due to the thin 0.037 in body, so expect reasonable life for typical jobsite use rather than indefinite longevity.
