The PALLMAN 670-48 Rotor Knife is a precision-ground rotor knife engineered as a drop-in OEM-spec replacement for Pallmann equipment. Manufactured to original-equipment tolerance and ground at our New England facility.

Specifications. Send us your part number, dimensions, or a photo of the existing blade — we’ll cross-reference from a catalog of hundreds of fitments and confirm OEM tolerance before quoting. Material substitutions (M2, D2, A11, powder metal, tungsten carbide inlay) available on request.

Pallmann tolerances are unforgiving — European OEM specs differ from US-built granulators in ways that show up after a few hundred run hours. We’ve ground to Pallmann spec for decades; the geometry is locked in.

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.
