Machinists and DIYers, this collet set is a lifesaver for tapping threads. You get 8 DIN collets covering sizes from M3 up to M16 (M3, M4, M5/M6, M8, M10, M12, M14, M16). They're designed for torque-sensitive tapping—if the tap hits too much resistance, the collet slips instead of breaking the tap or damaging your workpiece. That means fewer broken taps, less scrapped parts, and lower costs. They fit M16R electric tapping machines and PNEU-M12 pneumatic ones. Each collet has precise dimensions: for example, the M3 has a 3.5mm shank and 2.7mm square end. Made with high-precision CNC machining, they're durable and responsive. Just pop them in your machine, and you're set for smoother, safer tapping operations. Great for metalworking, fabrication, or any shop that does frequent threading. The set includes all the common sizes, so you're prepared for various jobs. A smart investment to improve your tapping success rate and save time and money on repairs.
