Frequently Asked Questions

1. What is a CAT Cool-Blast or Cool-Flange Shrink Fit Holder? ▼

A CAT Cool-Blast or Cool-Flange holder combines the strength of a CAT taper with internal coolant delivery. These holders provide excellent rigidity and cooling performance, ideal for heavy-duty CNC milling.

2. Why choose CAT Cool-Blast or Cool-Flange holders? ▼

The strong connection of a CAT taper ensures stability, while the cooling channels improve heat control. This combination helps achieve better tool life, cleaner finishes, and more efficient machining in demanding environments.

3. What CAT taper sizes are available? ▼

PAC Precision Tools USA offers CAT40 and CAT50 Cool-Blast and Cool-Flange holders. Each holder is built to deliver strong clamping and effective coolant flow for various CNC machines.

4. Are CAT cooling-enabled holders good for high-speed machining? ▼

Yes, these holders are balanced for high-speed operation and provide reliable cooling even at elevated RPMs. This helps reduce thermal deformation and maintains consistent accuracy.

5. How does the Cool-Flange feature work? ▼

Cool-Flange technology sends coolant outward near the flange area to wash chips away from the cutting zone. This keeps the tool cool and improves chip evacuation, especially in deep-cutting applications.

6. How can I maintain CAT Cool-Blast holders? ▼

Check coolant passages regularly, remove any clogging, and clean the taper after each use. Proper maintenance ensures stable coolant delivery and long-lasting accuracy.

7. Need help choosing the correct CAT cooling holder? ▼
