R8 Collet Set, 13-Piece 1/8–7/8 in, 0.0012 TIR

R8 collet set delivers tight, repeatable tool holding for cleaner cuts and more accurate milling. This 13-piece precision collet chuck set covers 1/8"–7/8" to match common end mill shanks, with 0.0012"/30 μm TIR for controlled runout on milling machines, drill presses, boring machines, and machining centers. Hardened, precision-ground 45# steel resists deformation under load, and each collet stores in a labeled box for fast size selection.

When runout and tool slip cost time and scrap, a matched R8 collet set helps stabilize your setup and keep tolerances on track. Use it for precision parts, high-strength grinding, or general shop work across metalworking and manufacturing applications where consistent clamping matters. With a broad clamping range and clearly labeled storage, you can change sizes faster and get back to cutting. Grab yours today and keep your R8 spindle ready for the next job.
