It accepts collets up to 1 inch capacity and mounts via an NMTB30 taper shank, making it compatible with standard NMTB30 spindle noses found on vertical milling machines and machining centers. Total Indicated Runout (TIR) is 0.0006 inches, supporting close-tolerance work where concentricity directly affects surface finish and tool life. Machinists and toolroom technicians install this chuck as part of a workholding or toolholding setup in manual or CNC milling environments.\u003c\/p\u003e\u003cp\u003eThis collet chuck is suited for production and job-shop milling applications where a full grip collet system is preferred over end-mill holders or side-lock style chucks. The full grip design contacts the tool shank along its full circumference, reducing vibration and improving pull-out resistance during cutting. It is a practical choice for shops running NMTB30-equipped Bridgeport-style mills or equivalent knee mills and light-duty vertical machining centers that use the NMTB30 spindle standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch maximum collet capacity accommodates a wide range of collet and tool shank sizes\u003c\/li\u003e\n\u003cli\u003eFull grip collet system provides uniform radial clamping force around the tool shank\u003c\/li\u003e\n\u003cli\u003eNMTB30 taper shank for direct mounting to NMTB30 spindle noses\u003c\/li\u003e\n\u003cli\u003e0.0006 inch TIR for consistent concentricity in close-tolerance milling work\u003c\/li\u003e\n\u003cli\u003eWeighs 2.96 pounds, a manageable weight for bench and spindle handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with NMTB30 spindle nose machines.

Power down and lock out the machine spindle before mounting or removing the chuck. Ensure the taper shank and spindle bore are clean and free of chips or burrs before seating the chuck to achieve proper contact and safe retention. Follow the machine tool manufacturer's draw bar torque and retention specifications for the NMTB30 interface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: Full Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: NMTB30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.96 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112808\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 230-7202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696312222002,"sku":"230-7202","price":153.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/330fa4439148b8976145595d9e8bdc3c.jpg?v=1788341352","url":"https:\/\/voomisupply.com\/products\/value-collection-230-7202-collet-chuck-1-in-nmtb30","provider":"Voomi Supply","version":"1.0","type":"link"}
