Tool Holder Bushings Supplier & Distributor in USA
Frequently Asked Questions
1. What is a tool holder bushing?
A tool holder bushing is an adapter used to fit smaller-diameter tools into holders with larger bore sizes. It ensures precise alignment and secure gripping of the tool.
2. How many types of bushings are available?
PAC offers multiple types including Type-C, Type-CS, Type-Z, Type-J, and Type-B. Each type differs slightly in shape, slot position, and length depending on machine and tool compatibility. View more.
3. What is the difference between Type-CS and Type-Z bushings?
Type-CS bushings have a set-screw slot and come with a straight-flanged design. Type-Z bushings are flush-fit style, meaning their surface stays nearly level with the holder—ideal for high-precision applications. Check specifications.
4. How are bushings used?
Bushings are inserted directly into the tool holder bore to safely mount smaller-diameter tools like drills or reamers. This helps minimize runout and maintain machining accuracy. Learn more.
5. When should bushings be replaced?
Bushings should be replaced if their bore becomes loose or shows signs of wear or grooves. Worn bushings can affect tool accuracy and damage the holder. Replacement options available.
6. Are bushings compatible with coolant-through systems?
Yes, certain bushings are designed specifically for coolant-through applications, allowing coolant to efficiently reach the cutting tool. Explore coolant-through bushings.
7. How do you ensure proper alignment when installing a bushing?
Align the set-screw with the slot on the bushing and tighten it securely. This prevents tool slippage and ensures accurate tool positioning. Installation tips.
8. Are bushings universal in size?
No, bushings are made for specific shank and holder bore sizes. It’s important to select the correct type and size for each application. See sizing guide.
