Sawdust and wood waste
For equipment reducing wood waste toward sawdust or smaller wood fractions, subject to machine and output requirements.
Wood Processing Replacement Knives
Alloy-steel replacement blade options for wood-processing equipment handling sawdust, branches, bamboo and other wood waste. Listed sizes include 80 × 70 × 10 mm through 420 × 160 × 15 mm, with custom sizes reviewed from a drawing or old blade.
The supplied product data lists alloy steel and an HRC 50–65 range. Final material grade, heat-treatment route, blade position and machine fit must be confirmed before quotation.

This product family is presented as a replacement and custom-supply starting point. A similar-looking blade is not automatically interchangeable between a chipper, sawdust crusher and wood shredder.
Dimensions follow the source listing format of length × width × thickness in millimetres. Use the table to identify a possible starting point; the machine seat, hole diameter, hole spacing, cutting direction and effective height still need to match.

Weights are supplier-listed reference values. The `888 × 88 × 8 mm` value in the source listing is treated as a custom-order placeholder, not as a standard size.
Chipper knives, sawdust-crusher knives and wood-shredder knives may look similar while using different seats, fixing patterns or cutting clearances.
Identify the chipper, sawdust crusher or shredder and provide its brand and model.
Confirm whether the part is a rotor knife, fixed knife, bed knife or another cutting component.
Record hole count, hole diameter or slot form, hole spacing, fixing direction and seat details.
Confirm blade thickness, cutting direction, effective height, edge form and working clearance.
Describe wood type, feed size, moisture, bark, sand, nails or other contamination.
State quantity, matched knives or related parts, destination and required delivery timing.
The product listing identifies wood as the application direction. The final selection depends on the feed condition and the machine’s cutting arrangement.
For equipment reducing wood waste toward sawdust or smaller wood fractions, subject to machine and output requirements.
Review the branch diameter, moisture, bark and possible dirt or metal contamination before selecting a profile.
Boards, offcuts and prepared wood chips require a review of feed size, cutting action and target output.
The listing’s mushroom-related wording refers to sawdust preparation for substrate applications, not to processing mushrooms themselves.
The supplied data gives a material category and hardness range, but the final specification should be recorded against the selected size and working duty.
The current product data identifies alloy steel. The exact grade, chemistry and supply condition are not specified and should be confirmed before production.
This is a supplier-provided range. Confirm whether it applies to every listed size or changes with material, heat treatment or application.
The listing mentions overall hardening, tempering, carburizing hardening and surface hardening. Do not assume all routes are used on one blade.
These images show the general flat, slotted and comb-like forms supplied in the source folder. They are visual references, not dimensional drawings.

A replacement blade should be reviewed as part of the cutting system, not as an isolated piece of steel.
Rounded edges, chipped corners, cracks, unusual vibration, changing output or repeated jams indicate that the blade area needs review.
Clean the mounting surface and verify fixing direction, cutting height, paired knife condition and working clearance according to the machine procedure.
If regrinding or reuse is considered, send current wear photos and target dimensions. Do not assume a worn blade can be restored without checking fit.
Do not mix new and heavily worn components without checking the resulting cutting height, clearance and rotor balance.
Custom supply is most efficient when the quotation is built around a clear production reference.
Share the machine type and model, old blade photos, dimensions, hole pattern, material and required quantity.
Review blade position, cutting direction, material grade, hardness requirement, heat-treatment route and any drawing or sample.
Record the approved size, holes, material, quantity and inspection requirements before production and delivery.
Short answers for replacement and custom-supply buyers.
The supplied listing covers sawdust crushers, wood crushers and chipper-related terms. The exact machine type and blade position must be confirmed from the machine model, drawing or old blade.
No. Hole count alone does not prove interchangeability. Check hole spacing, diameter or slot form, seat, fixing direction and cutting clearance.
Both appear as listed reference options in the supplied product data. Confirm the profile, hole pattern, material and machine fit before quotation.
HRC 50–65 is the supplier-provided range in the current listing. Confirm the applicable hardness for the selected size, material and heat-treatment route before ordering.
Send clear photos and, where possible, a physical sample or drawing. Include the machine model, blade position, key dimensions, hole pattern, material and quantity.
Those materials appear in the product naming or application references, but suitability depends on feed size, moisture, contamination, machine type and blade configuration.
Provide the machine brand and model, old blade photos, dimensions, hole or slot details, material being processed, quantity and destination. A drawing or sample is preferred.
Tell us the complete replacement scope. Related parts can be reviewed when the machine configuration and mounting relationship are confirmed.
