Inserts are the part of a carbide edge that touches the road, and they are also the part procurement documents tend to specify in detail. We manufacture the insert geometries used across snow plow edges, supply them loose or pre-welded, and hold the dimensional record for the batch.

Inserts or a complete edge?
Replacing inserts costs more workshop time than swapping a complete edge, but it keeps the steel carrier in service and it matches the way many municipal tenders are written. The honest answer depends on your workshop capacity and how your maintenance programme is structured.
| Replaceable inserts | Complete replacement edge | |
|---|---|---|
| Workshop time per change | Higher | Lower |
| Carrier reuse | Carrier stays in service | Carrier is replaced with the edge |
| Tender compatibility | Matches insert-specified contracts | Matches whole-edge contracts |
| Ride quality | Sensitive to welding quality | Consistent out of the box |
| Best for | Fleets with a capable workshop | Fleets that change blades in the field |
Dimensional control
Insert height, length and angle decide whether a repaired edge scrapes evenly or leaves a stripe. Every production batch is measured against the approved drawing, and the results are archived with the material certificate so a receiving inspection can be answered with a document rather than an assurance.
Spacing and density
How tightly inserts are set changes the character of the edge. Close spacing on a hard surface gives a cleaner scrape; wider spacing with a tougher grade survives gravel and stone. Both layouts are produced on the same line, and the choice is recorded on the drawing.
Can you match the inserts in our existing tender document?
Usually yes. Send the drawing or the tender schedule with dimensions, grade and quantity, and we will confirm what we can reproduce and where a substitution would be required.
Do you supply inserts loose or welded into the carrier?
Both. Many customers buy inserts for their own workshop, while others take pre-welded assemblies to reduce on-site labour.
How should worn inserts be inspected?
Look at the pattern rather than the depth. Even wear across the width means the grade is right; chipping at the trailing edge points to an impact problem or a bonding problem, and each has a different fix.
Is there a minimum order for a custom geometry?
It depends on the shape and the tooling it needs. Simple modifications carry a low minimum; a completely new press form is quoted with the tooling cost attached.
