Cutting blades
Edges and tooth profiles where hardness, toughness, flatness and sharpening dominate.
Blades, wear inserts and hard-contact metal parts are driven by edge geometry, hardness, toughness, abrasion, impact and finishing. Small size alone does not make MIM the right process.
This family covers blades, cutters, wear inserts and hard-contact components. Unlike general MIM marketing, the primary question is not geometry alone: material, heat treatment, toughness, abrasion, edge integrity and finishing define whether MIM, machining, stamping or a tool-steel route is appropriate.
Edges and tooth profiles where hardness, toughness, flatness and sharpening dominate.
Compact parts that see repeated sliding, abrasion or hard contact.
Teeth or contact features that need hardness and wear resistance.
Stops, noses or inserts where impact and local contact stress drive material and finishing.
| Component / condition | First route to evaluate | Why / watchout |
|---|---|---|
| Thin blade / cutter | Stamping / machining + heat treatment | Thin cutting geometry usually favors established blade/tool-steel routes; edge grinding and distortion control are critical. |
| Small complex wear insert | MIM + heat treatment / finishing | MIM may help when 3D geometry is complex and volume is high, but wear surfaces and toughness must be validated. |
| Simple hard pin / wear pad | Machining / grinding | Simple geometry with demanding hardness or finish often favors direct machining. |
| Tungsten / specialty wear component | Project-specific specialty route | Exact material, binder, density, brittleness and finishing must be confirmed; do not generalize from “tungsten steel” alone. |
| Low-volume custom cutter | CNC / EDM / grinding | Tooling economics often favor direct processes. |
Boundary: blades and safety-critical cutting elements need specialist material, heat-treatment, edge and system validation. MIM is only one possible manufacturing route for selected complex wear parts.

SINTS cutting reference
A hard-material component; material and service requirements are reviewed for each project.
SINTS wear-material referenceDefine tooth/edge profile, sharpness, burr direction and final sharpening or grinding process.
A harder part is not automatically a better part; impact and fracture risk must be balanced against wear.
Thin blades and precision contact parts can move during heat treatment, so datum and finishing strategy matter.
Abrasive particles, lubrication, impact, corrosion and mating material change the right material choice.
Nose inserts, jaws and repeated-impact wear parts.
