Alfa Tools Expands Recip Saw Blade Line

Morton Grove, Illinois

May, 2026

Reciprocating saws are an indispensible part of removing material. This is especially true in tight spaces. With that in mind, Alfa Tools leadership tasked the team with expanding our line of recip blades to give end users even greater cutting power. The result?

We've added two new recip blades to our line up. One is six inches in length and one is nine inches in length. Both new blades have 18 teeth per inch.

In reciprocating saw blades, 18 TPI (teeth per inch) is generally considered a fine-tooth blade configuration. The biggest advantageis cleaner, smoother cutting in thinner materials and metal applications.

Here's where 18 TPI shines:

1. Better for Thin Metal

At all times, an 18 TPI blade keeps more teeth engaged in the material. WIth 18 TPI, at least 3 teeth are always engaged in the material. Thin materials can "grab" or strip teeth if the pitch is too coarse.

Our new 18 TPI blades are ideal for:

Thin wall conduit
EMT
Sheet metal
Thin tubing
Metal studs
Automotive metal
Light gauge stainless

2. Smoother, Cleaner Cuts

More teeth means:

Less vibration
Less tearing
Reduced burrs
Better finish quality

That’s important in:

Finish/demo work
HVAC
Electrical installs
Automotive repair
Fabrication

A 10 TPI blade cuts faster, but an 18 TPI blade cuts cleaner. This is where knowing the job and what you want to accomplish matters.

3. Reduced Tooth Stripping

Fine teeth distribute cutting load across more cutting points.

Benefits:

Less aggressive bite
Lower chance of snagging
Better control
Longer life in thin metals

Coarse blades often destroy themselves quickly in thin steel because individual teeth hit too hard.

4. Better Control in Precision Cuts

18 TPI blades feel more controlled and less violent during cutting.

That matters when:

Working overhead
Cutting installed pipe
Cutting close to finished surfaces
Performing plunge or flush cuts

Tradeoff: Slower Cutting in Thick Material

The downside:

18 TPI removes less material per stroke
Slower in wood
Slower in thick steel
Can clog in soft materials

It is essential to choose the correct blade and teeth per in when selecting the right blade for the job. Customers rely on Alfa Tools to get the job done right.
