ASSORTS R8 7/16 Inch to JT-6 Taper ARBOR Adapter Sleeve for Precision Tooling and Machining

• R8 to JT-6 Precision Adapter:
This arbor adapter is designed for milling machines with an R8 spindle, such as Bridgeport and standard vertical mills. It allows your machine to seamlessly connect with heavy-duty drill chucks featuring a JT-6 (Jacobs Taper 6) bore.

• 7/16" × 20 UNF Drawbar Thread:
The rear end features a standard 7/16" × 20 UNF drawbar thread, which perfectly matches most R8 spindle drawbars. This ensures the arbor locks securely inside the spindle, preventing tool slippage during operation.

• Heavy-Duty JT-6 Mounting:
The JT-6 taper is known for its strong grip and stable design, making it ideal for larger drill bits and heavy drilling operations. Its tight taper fit eliminates play and ensures high machining accuracy.

• Industrial-Strength Alloy Steel:
Manufactured from premium alloy steel, this adapter is built to withstand demanding machining environments. The arbor is hardened and precision-ground to maintain long-term durability and dimensional stability.

• Minimum Run-Out & Low Vibration:
Thanks to precision grinding and tight manufacturing tolerances, the adapter maintains minimal run-out and reduced vibration, resulting in more accurate drilling and longer tool life.

• Versatile Tooling Solution:
Suitable for metalworking, fabrication, and general machining, this adapter provides a reliable interface for mounting JT-6 drill chucks and compatible accessories, making it an essential tool for professional workshops.
