Pro Grade CAT40 ER16 Collet Chuck Set Five Piece Heavy Duty Tool Holder Ready For High Speed CNC Milling And Dead On Precision Drilling With Rock Solid Accuracy And Clean Cuts

5-Piece CAT40 ER16 Collet Chucks for Precision CNC Milling.
✔️ 5-piece CAT40 ER16 collets hold tools with 0.0001 TIR at 20000 RPM.

This set of five heavy-duty tool holders is built right up for your CNC mill operations. Each chuck uses hardened alloy and ground surfaces to clamp your cutting tools firmly and true every time. You get precise drilling and clean cuts when you process aluminum or steel stock across production shifts.

✅ Achieve 0.0001 TIR accuracy for superior machining results on precision jobs.
✅ Switch tools in about 15 seconds using the grounded V-flange system.
✅ Handle loads up to 20000 RPM with G2.5 balanced heavy duty construction.
✅ Resist abrasion three times longer thanks to heat treated 40CrMnTi alloy.
✅ Run cool and avoid downtime with built-in cooling channels and oxidation finish.

💡 Why choose a hardened CAT40 tool holder for your CNC workflow?
These holders stay handy under pressure and keep your machine humming all shift.
- Ground flanges deliver rock-solid alignment to minimize vibration at high speeds.
- Heat-treated alloy bodies resist wear far longer than basic steel options.
- Balanced rotors protect spindle bearings from damage during deep cut operations.
- Calibrated runout ensures tight tolerances for clean finishes on hard materials.
