It accepts ER16 collets with a capacity range from 1\/16 inch minimum to 0.406 inches maximum, making it suitable for a wide range of small-diameter cutting tools. The chuck features a 4-inch projection and an overall length of 6.687 inches, providing reach into deep pockets or fixtures where shorter toolholders cannot access. A licensed machinist or CNC tooling technician installs and configures this holder as part of a precision toolholding setup.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is suited for production and job-shop environments running CNC vertical or horizontal machining centers equipped with a CAT40 spindle interface. It is commonly used when holding end mills, drills, reamers, and other round-shank tooling within the ER16 collet capacity range. The 4-inch projection accommodates setups requiring additional clearance between the spindle face and the workpiece or fixture. Through-coolant is not supported on this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in CAT40-equipped machining center spindles\u003c\/li\u003e\n  \u003cli\u003eER16 collet system with a capacity range of 1\/16 inch to 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e4-inch projection for extended reach in deep-pocket or tall-fixture applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 6.687 inches for predictable gage-line to tip dimensions\u003c\/li\u003e\n  \u003cli\u003eRated nut tightening torque of 42 ft-lb for repeatable clamping force\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant passages, keeping the design straightforward and cost-effective for standard flood-coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style toolholding solution for CNC machining centers with a CAT40 spindle interface, used with standard ER16 collets.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machining center spindle before inserting or removing the toolholder. Use a calibrated torque wrench to tighten the ER16 collet nut to the specified value to ensure proper clamping and avoid collet or chuck damage. Inspect the CAT40 taper and spindle bore for chips or contamination before seating the holder.\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: ER16\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: CAT40\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: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Tightening Torque\u003c\/strong\u003e: 42 ft-lb\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: 2.8 pounds\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: CAT40ER16-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51961900663090,"sku":"CAT40ER16-4","price":169.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7de28b04e42a6f12d21b7fb1579aafa.jpg?v=1789947343","url":"https:\/\/voomisupply.com\/products\/techniks-cat40er16-4-er16-collet-chuck-cat40-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
