speed precision tool holder designed for reliable, longlasting performance in demanding machining applications. Key benefits speed capability: Rated for 30,000 rpm to increase cycle rates and improve overall work efficiency. Stable balance: speed dynamic balance reduces vibration for smoother cutting and longer tool life. Durable construction: Carburized and quenched surface treatment produces surface hardness and strong wear resistance so the handle withstands impact loads. Industrialgrade materials: Made from quality metal for hardness, durability, and extended service life. Precision accuracy: Imported tool holders with taper accuracy AT3 (7:24 taper), coaxiality 5 μm, tool shank diameter variation 0.003 μm, insert seating 0.005 μm, and total runout 0.008 μm for consistent, repeatable results. Easy operation: Simple insert clip design for quick tool changes with reliable retention. Function, compatibility, and performance Function: Securely holds cutting tools at rotational speeds while minimizing runout and vibration to maintain cutting accuracy and surface finish. Compatibility: Designed for standard 7:24 taper tool shanks with AT3 taper accuracy; suitable for a wide range of milling and drilling toolholders that match these specifications. Size and fit: Meets precision tolerance values specified above to ensure coaxial alignment and minimal runout across compatible tool shank sizes. Material and treatment: Hardened metal body after carburizing and quenching delivers improved wear resistance and impact strength for industrial use. Typical applications speed CNC milling: Use in precision milling operations where 30,000 rpm capability and low runout improve surface finish and dimensional accuracy. Mold and die machining: Reliable taper accuracy and hardness help maintain tight tolerances during repeated roughing and finishing passes. Aerospace and precision components: Preferred for parts requiring tight coaxiality and minimal tool vibration to meet stringent geometric and surface requirements. Practical notes Ensure compatibility with your machine spindle and tool shank specifications (7:24 taper, AT3) before use. Regular inspection and cleaning of the taper/contact surfaces will help maintain accuracy and service life. Follow standard tool holder torque and clamping procedures to preserve balance and runout performance.
