DUAL CAT TAPER - COOL-BLAST - Cool-Flange Holder

Frequently Asked Questions

1. What is a CAT Dual-Contact Cool-Blast or Cool-Flange Holder? ▼

It is a shrink-fit holder designed to make contact on both the spindle taper and spindle face, providing superior rigidity. Combined with Cool-Blast or Cool-Flange cooling, it offers strong accuracy and excellent heat control.

2. What are the benefits of dual-contact cooling holders? ▼

Dual-contact improves stiffness and reduces vibration, while internal cooling reduces heat buildup. This allows for more aggressive cutting, improved surface finish, and longer tool life in precision machining.

3. Are these holders compatible with standard CAT machines? ▼

No, dual-contact holders work only with machines that support CAT dual-contact spindle systems. Always confirm compatibility before purchasing.

4. Are dual-contact cooling holders suitable for high-speed machining? ▼

Yes, they are fully balanced and offer better rigidity than standard CAT holders. Combined with directed coolant flow, they maintain cutting accuracy even at very high RPMs.

5. How do Cool-Blast channels benefit dual-contact holders? ▼

The cooling channels deliver coolant directly to the tool, reducing heat and preventing thermal expansion. This is especially important in high-precision, long-reach, or high-load applications.

6. What maintenance is recommended? ▼

Keep both the taper and face surfaces clean, maintain coolant passages, and check for clogging. Cleanliness ensures proper spindle contact and reliable coolant flow.
