Confirmed after engineering review and MOQ agreement (~100 pcs).

How buyers search for custom tools

We mirror intent with [material grade] + [profile/feature] + [size] + [tool type] so ads land here directly. Examples:

  • M42 step drill with pilot 18 mm + chamfer for valve body
  • M42 form tool radius 6 mm for fixture machining
  • M35 port tool SAE/JIC with counterbore and chamfer
  • M42 combination tool for counterbore + chamfer + spotface
Ready-to-copy brief: attach PDF/DXF/DWG + workpiece material + coating preference + batch size. Mention critical dimensions and tolerance stack-up if any.

Engineering & validation

  • Design review for reliefs, rake angles and chip evacuation before quoting.
  • Batch codes for traceability; inspection records can accompany first lots.
  • Edge prep and coating recommendations shared per application.
  • Compatibility checks with your tool holders and gauge requirements.
MOQ guidance: Most customs start at ~100 pcs; we confirm feasibility and schedule.

Where these tools run

  • Valve bodies and hydraulic components needing port tools.
  • Fixtures and jigs requiring repeatable form cutters.
  • Automotive and general engineering parts with combined operations.
  • Production lines that need fewer tool changes and consistent geometry.

Quality controls

  • Incoming HSS inspection and hardness checks.
  • In-process run-out and profile verification on CNC grinders.
  • Final dimension checks with gauges and micrometers; sample reports available.
  • Coating batches tracked to tool codes for repeatability.

What we need to quote fast

  • PDF/DXF/DWG with all dimensions and tolerances.
  • Workpiece material and machining setup (RPM, feed, coolant).
  • Quantity/annual usage and coating preference.
  • Any gauge references or acceptance criteria.
