It accepts ER25 collets with a capacity range of 3\/32 inch minimum to 3\/4 inch maximum, covering a wide variety of tooling diameters. The overall length is 5.18 inches with a 2.5 inch projection from the gauge line to the collet nose. This chuck is installed by qualified machinists and tooling technicians on vertical and horizontal CNC machining platforms where repeatable tool holding and concentricity are required.\u003c\/p\u003e\n\u003cp\u003eThis ER25 collet chuck is suited for production and job-shop CNC milling environments using CAT40 spindles. The 2.5 inch projection provides clearance for mid-reach applications where standard-length holders may cause spindle interference. The ER25 collet system is widely used across light to medium-duty cutting operations including drilling, reaming, and end milling. No through-coolant path is present in this model, making it appropriate for dry cutting 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\u003eCAT40 taper shank for direct mounting in CAT40 CNC spindles\u003c\/li\u003e\n  \u003cli\u003eER25 collet system with 3\/32 inch to 3\/4 inch capacity range\u003c\/li\u003e\n  \u003cli\u003e5.18 inch overall length with 2.5 inch projection for mid-reach clearance\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant, compatible with flood or dry cutting setups\u003c\/li\u003e\n  \u003cli\u003eSupports a broad range of ER25 collets for versatile tooling configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT40 spindle machines accepting ER25 collets.

Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or removing the chuck. Use a calibrated torque wrench and the appropriate ER25 collet nut spanner when seating collets to avoid over-tightening or under-tightening the nut. Inspect the CAT40 taper and spindle bore for chips, nicks, or contamination before installation to maintain proper seating and runout performance.\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: ER25\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\u003eOverall Length\u003c\/strong\u003e: 5.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 3\/32 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: 3.5 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: 22243-2.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52029188342066,"sku":"22243-2.5","price":205.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31e74ab0f0814455e56b25e2455c923d_6161793d-485b-4e53-98da-2d5818d62420.jpg?v=1790018328","url":"https:\/\/voomisupply.com\/products\/techniks-22243-2-5-er25-collet-chuck-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
