Morse Taper to R8 Taper Milling Machine Adapters
Convert tools with a Morse taper shank to an R8 shank for use in manual milling machines that have an R8 taper spindle. Holders are ground to accurate size.
Collet Chucks
Securely hold collets in the spindle of a milling machine.
Use a nut wrench (sold separately) to tighten the chuck nut and secure the tool bit in the collet.
Quick-Change Tool Holders for Milling Machines
After installing the R8 body in the milling machine spindle, tool holders can be switched out in seconds. To remove a tool holder, depress the brass locking button and rotate the collar on the R8 body. When a new tool holder is inserted, a spring-loaded pin snaps the collar back into the locked position.
