The NX5 designation indicates a 5:1 gear ratio, allowing a machine spindle running at up to 4,000 RPM input to drive the output spindle at up to 20,000 RPM. This makes the unit suitable for finish milling, engraving, and small-diameter drilling applications where standard spindle speeds fall short of optimal cutting parameters.\u003c\/p\u003e\n\n\u003cp\u003eThe tool collet system uses Nikken's proprietary SK10 format, accepting tools from 1.75 mm to 10 mm (0.069 to 0.394 in.) in diameter. The SK10 collet nut features a titanium nitride (TiN) coating rated at HV2,200 surface hardness, providing a high-grip, low-friction clamping interface compared to conventional ER systems. The output spindle is supported by four-point high-precision P4-grade bearings for accurate rotation at elevated speeds.\u003c\/p\u003e\n\n\u003cp\u003eA body-mounted stopper pin and compatible positioning block (not included) are required to prevent body rotation during operation. Serial number K-100 is visible on the unit body. Country of manufacture is Japan. Overall gauge length is 5.945 in., with a body diameter of 3.346 in. and a flange-to-nose projection of 1.811 in., per published Lyndex-Nikken catalog specifications. Collet availability and stopper block compatibility should be verified for the target machine before purchase.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0326-1191\u003c\/p\u003e","brand":"Nikken","offers":[{"title":"Default Title","offer_id":49487779791088,"sku":"m01191","price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/E8642CE9-7BA1-488A-A8AE-7ED60F3E2BE5.jpg?v=1774963387","url":"https:\/\/mroexchange.com\/products\/nikken-hispinner-spindle-speeder-cat50u-nx5-151-cat50-sk10-collet-175-to-10-mm-tool-capacity-51-gear-ratio-20000-rpm-max-output-orientation-axial-0326-1191","provider":"MRO Exchange","version":"1.0","type":"link"}
