Precision CNC Manufacturing
Factory Precision and Grinding Standards
CNCToolHolders operates a specialized CNC grinding facility dedicated to manufacturing high-precision tool holders, collets, and machine accessories. Equipped with optical inspection systems and cylindrical grinding machinery, every component undergoes quality testing to maintain concentricity limits down to 0.008 mm runout.
We produce BT, SK, and CAT tool holders along with ER collet systems engineered to DIN, ISO, and ANSI dimensional standards for direct supply to North American machine shops and distributors.
Quality Assurance Workflow
Four Step Manufacturing Cycle
01
Alloy Material Testing
Every batch of raw steel alloy undergoes spectro-analysis and flaw testing prior to initial turning and machining.
02
CNC Precision Grinding
Tool tapers and collet bores are precision-ground on CNC equipment to uphold strict 0.008 mm runout thresholds.
03
Optical Runout Inspection
Laser micrometers and optical measuring equipment verify critical taper geometries and concentricity across each batch.
04
Laser Etching & Dispatch
Part numbers and custom logos are laser-etched before vacuum sealing for guaranteed 5 to 20 day export dispatch.
Custom OEM and Private Labeling
Inquire about custom part marking, OEM packaging options, and direct factory export terms.
