Bandsaw blades for stainless steel
Stainless steel work hardens the moment a tooth rubs instead of cutting, so the edge has to bite from the first pass. High-performance bi-metal blades handle most stainless sections and honed carbide takes over on heavy and high-nickel work.
The problem with cutting stainless steel
Stainless steel punishes hesitation. When a tooth rubs rather than cuts, the surface work hardens, leaving a skin that is harder than the parent metal. Every tooth that follows meets that skin instead of fresh material, so it rubs too, hardens the surface further and the cut stalls in a cycle that blunts a blade in a fraction of its normal life.
Heat makes it worse. Stainless holds heat in the cut rather than carrying it away in the chip, so a blade that lingers runs hot at the tooth tip. HSS loses its edge as it overheats and the cut starts to wander and squeal.
The right blade breaks the cycle by taking a proper chip on every pass. A sharp bi-metal edge with a positive bite keeps each tooth cutting beneath the hardened layer before one can form. On heavy sections and high-nickel grades, honed carbide tips stay hard where an HSS edge would give up, which is why they take the top end of stainless work.

Getting the cut right
General rules that hold across machines. Exact widths, pitches and options are on each product page.
Match pitch to the section
Tooth pitch depends on how much metal each tooth crosses. Solid stainless bar wants a coarser pitch that gives every tooth room to take a full chip, while thin-wall tube and profile need a finer pitch so several teeth share the wall. Too coarse on thin sections strips teeth; too fine on solids clogs the gullets and rubs.
Keep the feed positive
Stainless work hardens the moment a tooth rubs, so set a feed that produces a continuous curled chip and hold it. Watch the swarf: tight curls mean the teeth are cutting, powder or dust means they are rubbing and hardening the surface for the teeth behind. Never pause the feed mid-cut with the blade still running against the work.
Break in a new blade
A new blade's tooth tips are razor sharp and can chip if driven at full rate into stainless from the first cut. Run the first cuts at a reduced feed so the tips wear to a stable edge, then bring the feed up to its working rate. A blade broken in properly cuts straighter and lasts noticeably longer.
Control heat with speed and coolant
Stainless holds heat at the tooth tip rather than shedding it into the chip, so run a slower band speed than you would for mild steel and keep flood coolant on the cut. Firm guide arms set close to the work stop the band twisting as it heats, which keeps the cut square through thick sections.
