The chuck features a 1 inch shank diameter and a 4 inch overall length with a 50 mm projection from the spindle face. It accepts ER32 collets with a clamping range from 1\/16 inch up to 3\/4 inch, covering a wide variety of end mill, drill, and reamer shank sizes common in production and job-shop environments. Machinists and CNC setup technicians are the primary users of this toolholder.\u003c\/p\u003e\n\u003cp\u003eThe 04839 is suited for straight-shank spindle connections on vertical machining centers and manual knee mills where ER collet systems are standard. The 50 mm projection provides clearance for moderate-depth workpiece features without requiring extended-reach tooling. Applications include milling, drilling, reaming, and tapping operations across a broad range of materials. No through-coolant path is present, making this chuck appropriate for dry or flood-coolant setups where internal coolant delivery is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER32 collet system with a clamping range of 1\/16 inch to 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e1 inch straight shank diameter for direct spindle mounting\u003c\/li\u003e\n  \u003cli\u003e4 inch overall length with 50 mm projection\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard ER32 collets for versatile tooling setups\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant  -  suitable for flood or dry machining environments\u003c\/li\u003e\n  \u003cli\u003e1 pound weight supports balanced operation at typical spindle speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard ER32 collets in straight-shank spindle applications on vertical machining centers and manual milling machines accepting a 1 inch straight shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at a complete stop before mounting or removing the chuck. Clean the shank and spindle bore thoroughly before insertion to prevent runout caused by contamination. Tighten the ER32 collet nut to the collet manufacturer's recommended procedure using a properly sized spanner wrench  -  do not use improvised tools that may damage the nut or collet seating surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 04839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52021161099570,"sku":"04839","price":235.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9798c675c718c895c2db3d50255a493_f04e47ae-a191-4833-b08f-076079d88298.jpg?v=1790012307","url":"https:\/\/voomisupply.com\/products\/techniks-04839-er32-collet-chuck-1-in-straight-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
