Best jigsaw blade for stainless steel

A clean edge setup for stainless steel, with fit checks and the reasons behind each property.

High for blade class; verify product rating

M42 bi-metal or carbide edge for stainless steel

Jigsaw can make this cut when machine fit, section thickness, tooth engagement, workholding, and dust or chip control are all verified.

Blade construction: M42 bi-metal or carbide edge
Teeth or grit: 14–18 TPIConfirm the blade maker’s stated thickness range; tube wall thickness matters more than outside diameter.
Tooth geometry: Milled wavy-set or ground metal tooth
Machine fit: T-shankConfirm clamp compatibility in the jigsaw manual; “universal” is not a guarantee.
Kerf / body: Blade body chosen for stiffness, curve radius, and access
Speed and feed: Lower speed; firm, continuous chip-forming feed. Do not let a dull blade rub.

Set up the cut

Do not dwell. Maintain chip-forming pressure with a sharp blade.
Lower speed; firm, continuous chip-forming feed. Do not let a dull blade rub.
Confirm clamp compatibility in the jigsaw manual; “universal” is not a guarantee.
Keep the shoe flat, minimize orbital action for brittle or metal work, and orient the presentation face for the selected tooth direction.

Avoid

Forcing a dull blade to recover feed rate.
Too few teeth in a thin wall or so many teeth that the gullets pack.
A blade that is too short for the stroke or too wide for the required curve.

EXACT MANUFACTURER EXAMPLE

Check the model, form and range together.

Bosch EXPERT Tough Metal medium T118EHM

Catalog option: 2608900562 (3-pack)
Workpiece: Stainless steel sheet · 2–5 mm sheet thickness
Source scope: Bosch GB catalog · checked 2026-09-21

The exact option lists an 83 mm overall length, 1.4 mm tooth spacing and a carbide edge. Overall length is not usable cutting depth. T-shank fit alone does not establish that the saw permits the job.

Boundary: Do not transfer this range to solid stainless stock, another blade code, a band saw or a reciprocating saw. Confirm the actual section and the tool manual; this is documented application evidence, not a SawMatch cutting test.

WHY THIS CLASS

The material and saw impose different constraints.

Stainless work-hardens when a dull blade rubs. Use a durable edge, lower speed, firm feed, and appropriate cutting fluid where the machine permits.

A reciprocating narrow blade makes a jigsaw adaptable, but blade body, tooth direction, width, and length matter as much as TPI.

The practical tradeoff

Confirm the blade maker’s stated thickness range; tube wall thickness matters more than outside diameter. Confirm clamp compatibility in the jigsaw manual; “universal” is not a guarantee.

SETUP SEQUENCE

Before the blade touches the work

COMMON MISTAKES

What invalidates the recommendation

Forcing a dull blade to recover feed rate.
Too few teeth in a thin wall or so many teeth that the gullets pack.
A blade that is too short for the stroke or too wide for the required curve.

Check the reasoning.

SawMatch translates source guidance into a neutral class; the purchased blade still needs its own application and thickness rating.
