Bi-Metal 25 Pack 9 in 14/18 TPI Reciprocating Saw Blades - Metal

In this review the Bi-Metal 25 Pack 9 in 14/18 TPI reciprocating saw blades is evaluated for tradespeople and DIYers who cut medium-thickness metal. The bottom line: these blades are a value-oriented option that delivers reliable metal cutting thanks to an M42 bi-metal edge with 8% cobalt and a variable 14/18 TPI tooth pattern. They are best for repetitive demolition tasks where cost per blade matters, and they come packaged in a convenient retractable storage box that keeps the set organized on the job.

Key Features

• M42 Bi-Metal Construction: The teeth contain 8% cobalt for improved heat resistance and edge life when cutting metal.
• Variable 14/18 TPI: The mixed tooth pitch with small gullets balances cutting speed and smoother cuts through 1/16 in to 5/16 in medium metals.
• 0.04 in Thickness: Each blade is thicker than many economy blades, which helps resist bending and improves durability during demolition.
• Universal 1/2 in Shank: The standard shank fits the major reciprocating saw brands for quick blade changes in the field.
• 25-Piece Kit with Case: A large quantity pack plus a retractable storage box reduces trips to the supply cabinet and keeps blades protected between jobs.

Who It's For

This pack is aimed at mechanics, contractors, and serious DIYers who regularly cut pipes, angle steel, vehicle panels, and other medium metals and want a low cost-per-blade option that still uses a high-speed M42 edge for better wear resistance.

Those who need ultra-long life for heavy industrial cutting or require blades for very thin sheet metal or wood should consider more specialized blades; this set is optimized for medium-thickness metal work between 1/16 in and 5/16 in.

Pros & Cons

Pros

• Good value for money with 25 blades and a storage box for busy jobsites.

• Variable 14/18 TPI tooth pattern provides a balance of speed and cut control for medium metals.
