Collet | Collet | Chuck | Milling Holder Type OZ8 A according to DIN 6388 A | ISO 10897 A, EU standard 401 E - also called Kress collet - Bore: 1/4 inch (6.35 mm) (clamping range: 2.5-3.0 mm) + union nut | clamping nut with M17x1 internal thread in Sparset. Compatible with the following milling motors | grinding motors | upper chamfers | milling spindles | spindle motors: KRESS | AMB - FME FM 6955 | OF 6990 E | FM 6990 E and SUHNER - UAD 30 RF. Advantages with our collets: robust and durable as made of high-quality material (alloy spring steel with high carbon content) and completely case-hardened. High accuracy of fit and dimensional accuracy. 100% compatible with the above spindles. High clamping force. Holding force thanks to flat cone angle (1:10). No slipping of the tool or damage to the spindle. High precision with top concentricity. for an optimal and Clean work result - quick and easy tool change - we recommend using its own union nut for each collet as the clamping sleeve sits relatively firmly in the nut - reduced tool wear with extended service life due to vibration-damping properties.
