Built with a CAT40 taper shank, it accepts cutting tools with a 0.25 inch bore diameter and provides a projection of 3.74 inches from the spindle face. The adapter features through-coolant capability, directing coolant directly to the cutting zone for improved chip evacuation and tool life. With an overall length of 6.43 inches and a nose diameter of 0.826 inches, it delivers a compact, balanced profile suitable for high-speed work. This holder is balanced to 45,000 RPM, making it appropriate for high-performance machining centers requiring tight runout tolerances. Weighing 2.62 pounds, it is a solid, production-grade component installed by CNC machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis shrink-fit adapter is used in CNC vertical and horizontal machining centers equipped with CAT40 spindle interfaces. It is well suited for high-speed milling, drilling, and finishing operations where tool concentricity and balance are critical. The through-coolant feature makes it a practical choice for deep-cavity work or applications where flood coolant alone is insufficient. A clamping depth of 1.023 inches provides secure tool retention when used with compatible shrink-fit induction heating equipment. Typical users include production machinists and toolroom technicians working in aerospace, automotive, mold and die, and general metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting to standard CAT40 spindles\u003c\/li\u003e\n  \u003cli\u003e0.25 inch bore diameter accommodates common shank-size cutting tools\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design channels fluid directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eBalanced to 45,000 RPM for stable high-speed machining\u003c\/li\u003e\n  \u003cli\u003e3.74 inch projection with 0.826 inch nose diameter for reach into confined features\u003c\/li\u003e\n  \u003cli\u003e1.023 inch clamping depth for secure shrink-fit tool retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style shrink-fit tool holder for CNC machining centers with a CAT40 spindle interface.

Power down and lock out the machining center spindle before mounting or removing the holder. Verify through-coolant port alignment with the machine spindle before torquing the retention knob to the spindle manufacturer's specification. A licensed machinist or qualified CNC toolroom technician should perform setup to ensure proper balance and runout compliance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eHole Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.826 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 1.023 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 45,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.62 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02753252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558021660978,"sku":"02753252","price":273.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/600bf632dc0ed82cc4a608f0d98d3c3f.jpg?v=1786401100","url":"https:\/\/voomisupply.com\/products\/seco-02753252-shrink-fit-tool-holder-cat40-0-25-in","provider":"Voomi Supply","version":"1.0","type":"link"}
