The BUSS – CONDUX 400/600 300/600 Rotor Knife 23.228 x 6.543 x .709 is a precision-ground rotor knife engineered as a drop-in OEM-spec replacement for TRIA equipment. Manufactured to original-equipment tolerance and ground at our New England facility.

Specifications. Dimensions: 23.228 x 6.543 x .709. Material substitutions (M2, D2, A11, powder metal, tungsten carbide inlay) available on request — we’ll recommend the right steel based on your run hours and material hardness.

TRIA’s Italian build tolerances differ enough from US/German granulators that a generic-spec blade will under-perform. We grind to TRIA spec — including 30° and 45° bevel variants — and we’ll cut a custom bevel if your application calls for it.

Already have this blade? We’ll regrind it. Most plants save 40–60% by regrinding existing blades instead of buying new — and most OEM steels still have life left long after operators assume they don’t. Send us your worn set and we’ll tell you honestly whether a regrind cycle still works.

Same-day pickup across New England — MA, NH, CT, RI, VT, ME. Custom dimensions, non-standard materials, and one-off retrofits welcome. Call 508-987-6800 or request a quote online. 25+ years of industrial blade service to OEMs, recyclers, packagers, paper mills, and food processors.
