Keyless Drill Chucks with Integral Arbor
The integral arbor is more rigid for greater accuracy than a drill chuck used with a separate arbor.
R8 taper spindles are often found on manual milling machines.
Also Available: Replacement hoods, ball bearing sets, collars, jaws sets, jaw guides, shells, and drive pins. Select 30075A6 and specify replacement part and Albrecht model number.

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.
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.

Boring Tool Holders for Milling Machines
Instead of widening a hole using a lathe, which turns the workpiece while the cutting tool stays still, use these holders to turn your boring bar in a milling machine and keep the workpiece stationary. They’re good for creating holes that are too large to drill or a diameter you don’t have a drill bit for. To help you bore holes to precise diameters, these holders have an adjustment dial with fine increments. Mount them in your milling machine using their shank. They’re also known as boring heads.
