Product information
Description
Wide Compatibility: Compatible with ER11A and ER11 collets and 8mm motor shafts on desktop CNC routers, spindles, and drills.
Quick Extension: Converts an 8mm shank into a collet end; the 40mm body increases reach and allows for faster tool changes in tight fixtures, jigs, and compact housings.
Precise Fit: 16mm outside diameter matches common collets; 0.02mm bore tolerance on 8mm collets maintains concentricity to reduce chatter and improve surface finish.
Durable Construction: Steel body with ground mating surfaces; The clamping nut (19 mm OD, 9 mm ID) provides stable clamping for milling, drilling, and engraving tasks. Versatile use: suitable for PCB routing, acrylic cutting, wood carving, and light metal finishing in workshops, fabrication spaces, classrooms, and small-batch production.
