What are TYPE-B Bushings used for in CNC toolholding?

TYPE-B Bushings are precision sleeves used to reduce the bore size of tool holders, allowing smaller diameter tools to fit securely. They ensure concentricity and minimize vibration during machining. You can view them online at pactoolsusa.com.

How is TYPE-B different from other tool holder bushings?

TYPE-B Bushings typically feature a solid construction without coolant-through capabilities, making them ideal for standard dry or external coolant operations. Their simplicity and precision make them versatile for general CNC use. More details are available at pactoolsusa.com.

Are TYPE-B Bushings compatible with end mill holders and boring bars?

Yes, TYPE-B Bushings are made to industry-standard outer diameters and lengths, making them fully compatible with most end mill holders, boring heads, and collet chucks. Explore size options at pactoolsusa.com.

What material is used in TYPE-B Bushings?

These bushings are manufactured from hardened and precision-ground alloy steel to deliver long-term durability and repeatable accuracy even under heavy-duty machining. Visit pactoolsusa.com for specifications.

What types of machining benefit from TYPE-B Bushings?

TYPE-B Bushings are widely used in turning, milling, and drilling operations across the automotive, aerospace, and metal fabrication sectors — wherever stable toolholding is required. Learn more at pactoolsusa.com.
