Short BT30-BT40 ER25-ER32 Collet Chuck Precision Tool Holder CNC Lathe Engraving

Short BT30-BT40 ER25-ER32 Collet Chuck Precision Tool Holder CNC Lathe Engraving. This short precision tool holder is designed for CNC lathe and milling machines, offering stable performance and accurate positioning. Made from durable 20CrMnTi with a hardness of HRC54 to 58 and a carburizing depth greater than 0.8, it delivers long service life and consistent machining results. The built in nut design reduces resistance and vibration during cutting, improving processing quality and stability. The holder supports G2.5 dynamic balancing at 20000 rpm and offers taper accuracy less than or equal to AT3. The inner cone is measured with standard pneumatic instruments to ensure a contact area ratio above 90 at the large end. It provides precision less than or equal to 0.002 and is suitable for medium speed precision machining. The clamping range is 1 to 16 mm for ER25 and 3 to 20 mm for ER32. Precise positioning for stable CNC machining. Durable 20CrMnTi construction with high hardness. Reduced vibration and resistance for improved finish. High accuracy and consistent taper performance. Suitable for medium speed precision applications. 1 piece built in tool holder.
