Cermet is a composite of ceramic particles in a metal binder. It sits between carbide and ceramic on the hardness scale: harder and more heat-resistant than carbide, but far tougher than a pure ceramic insert. On a circular saw blade that combination is used where carbide wears too fast but the material is still being cut with a toothed blade rather than ground.
This blade carries cermet tips on a hardened saw body, for cutting solid steel sections - particularly medium and high carbon steel, where carbide tips tend to wear or break down at the cutting edge.
Where cermet beats carbide
Carbide is hard, but it is also brittle under heat. In medium and high carbon steel, the cut runs hot and the tooth edge reaches temperatures where the carbide binder starts to soften and the edge wears quickly. Cermet keeps its hardness at those temperatures, so the cutting edge stays sharp for longer.
The practical effect is threefold: lower heat build-up in the workpiece, lower cutting load on the machine, and a noticeably better surface finish. On a solid section that finish is what decides whether the part goes straight to the next operation or needs a second machining pass, and removing that pass is usually where the cost saving sits.
Cutting load and machine capability
Cermet is harder than carbide, and it is also less tolerant of shock. It suits a machine that feeds steadily and clamps the workpiece rigidly - a cold saw or cut-off saw with a controlled feed, not a hand-fed chop saw. If the blade is allowed to chatter or the material is allowed to move in the clamp, the tips will chip rather than wear.
Matching the blade to the steel
The blade is intended for solid steel sections rather than tube or thin-wall profile, and for medium and high carbon grades rather than mild steel. On low-carbon or free-machining steel, a coated HSS or carbide blade is usually the more economical answer; cermet becomes worth its price when the steel is hard enough that carbide tips break down before they wear out.
How to specify the blade
Four values decide the order: outer diameter, thickness, bore and tooth count, with the steel grade and section size setting the last two. If you are replacing an existing blade, send a photograph with the markings visible plus the machine make and model, and we will match the specification.
Cermet is the answer when the steel is hard enough to take the edge off carbide.

Frequently asked questions
What do I check before ordering?
Match three things against the machine: the outer diameter against the saw’s capacity, the bore and pin holes against the spindle, and the tooth geometry against the section being cut. The bore is easy to measure; the pin holes are where machines of the same brand often differ. Where the arbor differs, the same tooth geometry is built to your spindle rather than you adapting the machine.
Which materials does it cut?
Solid steel sections, medium and high carbon steel. Stay inside that range: a blade run in harder or more abrasive material than it was ground for loses its edge quickly, and the cut quality drops before the edge visibly fails.
What should I quote when I inquire?
Cermet Tipped Circular Saw Blade for Medium and High Carbon Steel — plus the quantity and the machine make and model. Those three are enough to confirm the specification, the minimum quantity for the size and the production lead time in the quotation. When replacing a worn blade, a photograph of the marking stamped on the old blade shortens the check further.
