LÖSNING OZ Collet (OZ16 / OZ20 / OZ25 / OZ32)

Genuine LÖSNING OZ-series collets for OZ-type collet chucks and pull-back tool holders, stocked by San Tools in the UAE. OZ collets give a wider clamping range and higher gripping force per collet than ER collets, making them a common choice on production milling and drilling heads. Available across the OZ16, OZ20, OZ25 and OZ32 body sizes, covering bore diameters from 2mm up to 32mm.

Features

• Wide Clamping Range — each OZ collet covers a broader bore range than an equivalent ER collet, cutting down the number of collets needed per job
• High Gripping Force — the OZ slit-collar design distributes clamping pressure evenly along the full collet length for a firmer, more concentric grip
• Hardened & Ground Construction — precision-ground bore and OD for true running and long service life under repeated clamping cycles
• Four Body Sizes — OZ16, OZ20, OZ25 and OZ32 cover small precision work through heavier-duty milling and drilling
• Direct Fit — drop-in replacement for OZ-type collet chucks and pull-back tool holders already in use on the shop floor

How to Use

• Match the Body Size — confirm your collet chuck or holder is the OZ16/OZ20/OZ25/OZ32 series before ordering a collet
• Select the Bore Diameter — pick the collet whose bore matches your tool shank diameter for maximum grip
• Clean Before Fitting — wipe the collet bore and holder taper free of chips and oil before inserting the tool
• Torque Evenly — tighten the retaining nut to the holder manufacturer's spec to seat the collet squarely
• Inspect Regularly — replace collets showing bore wear, chatter marks, or a loose grip on the tool shank
