MT4 Drill Chuck, 0.01 Precision, 52 HRC Steel

【0.01mm Accuracy】0.01mm precision control: Designed for a tight fit, this arbor significantly reduces runout, meeting the requirements of high-precision machining and improving thread and surface quality.
【Hardened Steel Shank】Heat-treated steel shaft with a hardness of 52 HRC, providing high torsional strength and toughness that prevents deformation under heavy drilling loads.
【Corrosion Protection】Electrolytic coating across the entire body, creating a wear-resistant layer that prevents rust and seizing, even in the presence of cutting fluids in the workshop.
【Flat Shank Drive】The flat shank configuration ensures a secure and positive lock-in, preventing slippage during operation and guaranteeing stable torque transfer for smoother drilling.
【Universal Compatibility】This adapter effectively reduces the original parameter requirements of your lathe or drill, serving as a durable link between your MT4 spindle and your JT3 tooling.
