3piece Morse taper adapter set for MT1 to MT2, MT2 to MT3, and MT3 to MT4 transitions, designed for lathe and milling machines to expand tool compatibility with different shank sizes in workshop environments Durable alloy steel construction with precisionmachined tapers provides secure tool mounting, minimizes wobble, and maintains accuracy during speed drilling and milling operations Easy to use: insert the smaller taper tool shank into the adapter and attach the larger taper end to the machine spindle for quick tool changes, reducing setup time for professional and hobbyist machining Broad compatibility: covers essential taper transitions from MT1 to MT4, enabling a single machine to work with drills, cutters, and accessories across MT1 to MT4 standards for metalworking, woodworking, and general machining tasks Use scenarios: In a milling machine, swap MT2 to MT3 tooling to accommodate different cutters without changing spindles On a lathe, mount MT1 tools through MT1 to MT2 adapters to handle smalldiameter workpieces In a general , use MT3 to MT4 transitions to access a wider range of accessories with existing equipment across MT1–MT4 standards
