Key takeaways
- Blade fit: Confirm the exact length, width, and thickness required by your saw before comparing tooth counts. A blade that is only slightly wrong may not track or tension safely.
- Tooth pitch: Higher TPI is generally better for thin material, while lower or variable TPI clears chips more effectively from thicker stock. Aim to keep several teeth engaged in the work at once.
- Construction: Bi-metal blades combine a flexible alloy backing with hardened high-speed-steel teeth. They are usually the most versatile choice for a home metalworking shop.
- Tooth pattern: Regular, wavy, raker, and variable-pitch designs balance smoothness, speed, vibration, and chip removal differently. Match the pattern to both material thickness and cut quality.
- Machine type: Stationary saws typically accept longer, wider blades than portable models. A portable blade such as the Bosch CBS1418 is useful for on-site work, but it is not interchangeable with a 93-inch shop-saw blade.
What's inside
Choosing a metal-cutting band saw blade is less straightforward than it looks. Tooth count, blade width, material, and tooth pattern all affect whether a cut feels controlled or turns into chatter, heat, and premature wear. For furniture makers, the wrong blade can also leave rough edges that add unnecessary cleanup to brackets, frames, legs, and hardware projects.
This guide focuses on dependable blades for stationary and portable band saws, with attention to tooth geometry, bi-metal construction, sizing, and the kind of work each option suits best. Whether you are cutting thin-wall tubing, solid bar, angle iron, or general fabrication stock, these picks cover practical workshop needs without sacrificing a tidy finished result.

The Best Band Saw Blades For Metal (2026)s Reviewed
Imachinist S933414 M42 Bi-Metal Blade
The Imachinist S933414 uses an M42 bi-metal tooth edge in a 93-inch by 3/4-inch format, with a versatile 10/14 TPI pitch. It is a strong all-rounder for a home workshop cutting tubing, angle stock, and medium-thickness steel where durability and a reasonably clean finish matter equally.
Imachinist S93121224 24 TPI Blade
With a 93-1/2-inch length, 1/2-inch width, 0.025-inch thickness, and fine 24 TPI tooth count, this Imachinist blade is aimed at thinner metal and detail-oriented cuts. Its fine pitch can produce a smoother edge on light stock, though it is not the blade to reach for when cutting large solid sections quickly.
Lenox Diemaster 2 Vari-Raker
The Lenox Diemaster 2 combines bi-metal construction with a variable 6-10 TPI pattern, positive rake, and a raker-set tooth design. That combination makes it an appealing upgrade for demanding fabrication work, particularly when you want steadier chip removal and less vibration across changing material thicknesses.
Lenox Classic Tuff Tooth 18 TPI
Lenox’s Classic Tuff Tooth blade measures 93 inches by 3/4 inch and uses an 18 TPI wavy-set pattern with positive rake. It is well suited to users who value a controlled, relatively smooth cut in thinner sections but still want the toughness of a bi-metal blade for regular shop use.
BOSCH BS9312-18MA Metal-Cutting Blade
The Bosch BS9312-18MA is a 93-1/2-inch, 18 TPI stationary-saw blade designed specifically for metal cutting. Its straightforward specification makes it a sensible replacement for general fabrication, especially when you want a familiar brand and a fine-tooth option for thinner work.
Frequently Asked Questions
What TPI is best for cutting metal?
There is no single best TPI for every job. Fine pitches such as 18 or 24 TPI suit thinner sheet, tubing, and small profiles, while 6-10 or 10/14 TPI is more appropriate for thicker sections and general-purpose cutting.
Are bi-metal band saw blades worth buying?
For most home workshops, yes. Bi-metal blades offer a useful balance of flexibility, tooth hardness, and heat resistance, making them more forgiving and longer-lasting than basic carbon-steel blades when cutting steel and other tough metals.
Can I use a metal-cutting blade on wood?
You can physically cut some wood with a metal blade, but it is rarely a good choice. The tooth pattern is designed for chip control in metal, so wood cuts may be slow, rough, and prone to clogging; use a dedicated wood blade instead.
What is a good portable option?
The Bosch CBS1418 three-piece set is designed for portable band saws and includes 28-7/8-inch blades in a 14-18 TPI general-purpose range. Check your tool’s required dimensions carefully, since portable and stationary blades are not interchangeable.
Final Thoughts
For a versatile stationary-saw setup, the Imachinist S933414 is an excellent starting point, while the Lenox Diemaster 2 is the more refined choice for demanding or variable work. If your projects mainly involve thinner metal and clean edges, the Lenox Classic Tuff Tooth or Bosch BS9312-18MA deserves a close look.
