The CAT40-ER32-4 Tool Holder is a precision collet chuck system designed for CNC milling and turning centers with CAT40 taper spindles. It combines a CAT40 taper shank compliant with DIN 69871 and ISO 7388 standards with an ER32 collet system that grips tool shanks from 3.17 mm to 20 mm in diameter. The holder is machined from 20CrMnTi alloy steel, hardened to HRC 56-58, ensuring rigidity during high-speed cutting operations.
The ER32 collet mechanism uses a split-sleeve design with a 1:10 taper to provide uniform clamping force around the tool. This design is standard for medium-duty milling applications where vibration damping and concentricity are critical. The holder is not designed for heavy roughing or high-torque drilling; it is intended for finish milling, drilling, and tapping. The surface finish on the taper is ground to Ra 0.4 µm to ensure repeatable tool positioning.
This tool holder is purchased by CNC machining shops, tooling distributors, and contract manufacturers in Europe, North America, and Southeast Asia who require cost-effective replacements for worn or damaged units. Buyers typically order in quantities of 5 to 50 units, with packaging in individual plastic cases inside cartons. The supplier does not specify lead time or MOQ, but standard shipping is FOB Luoyang. Payment is typically via T/T, and the product does not include collets or wrenches.

Before ordering, confirm that the CAT40 taper matches your machine's spindle by comparing the flange dimensions and keyway position with your existing holder. Verify the ER32 collet bore size is compatible with your tool shanks. Request a sample unit if possible, or ask for photos of the actual product, including the manufacturer's marking and surface finish quality.
Lead time is not specified but typically ranges from 10 to 20 days for standard orders. The supplier offers FOB Luoyang as the default Incoterm, meaning the buyer arranges and pays for international shipping. Payment is usually by T/T in advance. Confirm packaging includes individual plastic cases to prevent scratches, and ensure cartons are labeled for customs clearance with material and HS code details.
Upon receipt, inspect the taper surface for scratches or burrs that could affect repeatability. Use a dial indicator to measure runout on a test tool installed in the collet. Check that the collet nut threads engage smoothly without cross-threading. Retain the original packaging and documentation. If used in high-precision work, request a dynamic balancing certificate or perform your own balance test before use.
