Ultra-Precise Clamping: This BT30-ER32-70 CNC toolholder delivers exceptional runout accuracy of just 0.002–0.005mm, ensuring vibration-free high-speed milling and consistent tool life — perfect for precision aerospace, mold, and automotive CNC machining where repeatability matters most.
Heavy-Duty Impact Resistance: Built with carburized and quenched 20CrMnTi steel (52–58 HRC), this BT30-ER32-70 CNC toolholder withstands aggressive cutting loads and repeated impacts up to 30,000 RPM without deformation or loosening — ideal for demanding end-milling, drilling, and reaming operations.
Versatile Tool Compatibility: The BT30-ER32-70 CNC toolholder securely holds standard ER32 collets and accepts a wide range of cutting tools including end mills, drills, reamers, and engraving bits — making it a go-to solution for machinists, CNC shops, and prototyping labs across metal, plastic, and composite materials.
Operator-Safe Precision Craftsmanship: Featuring a smooth, burr-free surface finish from refined machining and heat treatment, this BT30-ER32-70 CNC toolholder prevents hand abrasion during frequent tool changes while maintaining tight coaxiality and long-term dimensional stability even after hundreds of clamp/unclamp cycles.
Ready-to-Use Industrial Design: At 70mm working length and 50mm nut diameter, this BT30-ER32-70 CNC toolholder fits standard BT30 spindles with 7/24 taper and ships with one fully assembled, pre-tested unit — no calibration needed, just mount and machine with confidence on Haas, Okuma, Doosan, and other BT30-compatible CNC lathes and mills.
