Brass Collet 4485 — Durable, precise collet for rotary tools and flex shafts Key benefits Reliable grip: Securely holds small shank bits, burrs and accessories to reduce wobble and improve precision. Built for durability: Made from higher-quality brass and full-metal construction to prevent the cracking and failure common with plastic nuts and low-grade materials. Easy to use: Simple installation and removal for quick tool changes during projects. Sizes included Available in four collet sizes: 1/8, 3/32, 1/16, 1/32 (inch). Compatibility Compatible with most rotary tools and flex shafts. Not compatible with collet models 1 and 2, or series 1 (and earlier) of models 260, 270, and 280. Performance and material Brass construction provides a better balance of strength and wear resistance than inexpensive plastics. All-metal design resolves common quality issues such as nut breakage and premature wear, extending service life and maintaining consistent clamping force. Typical applications Jewelry making and watch repair: reliably hold small burs and polishing bits for precise detail work. Model making and hobby work: drill, cut, and shape small parts with reduced vibration and improved accuracy. Grinding, polishing, and light metalwork: secure mounted points and stone accessories for consistent surface finishing. What you get A set of collets (model 4485) in the specified sizes, designed to improve durability and maintain a secure fit across compatible rotary tools and flex shafts. Note Ensure your tool model is not among the excluded models before purchase to guarantee compatibility.
