No, these are R8 collets specifically designed for R8 spindle tapers and are not compatible with ER collet chucks.
The set is precision-ground to a TIR (Total Indicator Reading) of 0.0012 inches (30 μm).
The internal drawbar thread is standard 7/16-20 UNF.
Keep them in the original labeled box and ensure they remain coated with a thin layer of anti-rust machine oil.
Yes, the 13-piece set includes 1/2, 1/4, 1/8, 11/16, 13/16, 3/16, 3/4, 3/8, 5/16, 5/8, 7/16, 7/8, and 9/16 inch sizes.
Inspect the spindle taper and the collet for debris or burrs; clean both surfaces thoroughly.
Verify that the drawbar is tightened to the correct torque and check that the collet size matches the tool shank precisely.
Clean the surface with a light abrasive pad or solvent, then re-apply a high-quality anti-rust oil to protect the steel.
To install, ensure your R8 spindle taper is clean and free of debris. Insert the collet into the spindle, aligning the keyway, and thread the drawbar into the internal 7/16-20 UNF thread until snug. Do not overtighten, as this can stress the threads.
