Features: High accuracy grinding: The inner and outer conical surfaces are processed by full grinding technology, with high concentricity, ensuring tool stability and precise machining. Strong and tough substance: Composed of excellent alloy steel, it has high hardness and strong wear resistance after quenching care, and has a long service life. Global variable diameter: As an intermediate sleeve, it can adapt to machine tool spindles and cutting tools with different Mohs taper angles, expanding equipment capabilities. Safe and consistent: Some sleeves have a flat tail structure, which can effectively transmit twist and prevent tool detachment, ensuring safety. Standardized design: strictly following the Mohs taper standard, with good universality and high compatibility with various drilling machines and lathes. Specifications: Substance: Metal Model: Refer to the product specification diagram Package Includes: Mohs Cover × 1 note: Please allow 1-3cm errors due to manual measurement.
