CNC turning and milling collet chuck, industrial tool accessories, hardware, M12 NT30 ER25 - Universal mounting

Features:1.WEAR-RESISTANT ALLOY STEEL: Made of high-quality 40Cr alloy steel, offering superior wear resistance and more stable performance.
2.HIGH HARDNESS AND STRENGTH: Vacuum hardening treatment achieves carbon-oxygen co-infiltration, enhancing the tool's hardness.Blackening treatment provides high surface hardness, strong fatigue resistance, and high wear resistance. It maintains the strength and toughness of the low-carbon steel core after hardening, allowing the handle to withstand a certain impact under load, making it more durable.
3. FULLY GROUNDED PROTECTIVE: The shaft is fully ground, effectively protecting the connection of the conical hole in the drive head
4.HIGH CENTERING ACCURACY: The surface is bright, beautiful, and elegant; the shank hole is finely ground, and the centering accuracy is high.
5.DISTRESSED PRESSURE: The holder is integrally formed, with good structural rigidity.When in use, the pressure is dispersed across the precise needle rollers of the cage, making it suitable for processing large quantities of material.
