Quality, Inspection & Delivery
Our solid carbide PCB drills are controlled through material verification, precision grinding, in-process measurement and final inspection. Key dimensions, drill-point geometry, flute condition, ring position, surface finish and product identification are reviewed according to the approved specification or drawing before packing.

Three-Stage Quality Control
Inspection checkpoints are arranged around the manufacturing process to support dimensional consistency, stable hole quality and repeat-order control.
Incoming Material Control
Carbide grade, drill blanks, positioning rings and supplied material information are checked against the production requirement.
In-Process Grinding Control
Drill diameter, point geometry, flute profile, flute length, shank dimensions and ring position are monitored during precision grinding and assembly.
Final Drill Inspection
Finished PCB drills are reviewed for specified dimensions, runout, drill-point and cutting-edge condition, ring position, marking and packing identification.
Key Inspection Characteristics
Inspection requirements are confirmed according to the standard PCB drill specification or the approved custom drawing.
| INSPECTION ITEM | CONTROL FOCUS | CONFIRMATION BASIS |
|---|---|---|
| Drill Diameter | Cutting diameter and dimensional consistency | Standard specification or approved drawing |
| Flute Length | Effective drilling length and flute consistency | Confirmed product size or drawing requirement |
| Shank Diameter | Clamping-section dimension and surface condition | Applicable shank specification |
| Overall Length | Total drill length | Standard size matrix or approved drawing |
