For job shops and others machining a wide variety of materials, general-purpose end mills offer a nice balance between performance, tool life, and inventory costs. Yet some metals are either so difficult to cut or machined in large enough quantities that only the very best combination of carbide, coating, and geometry will do.
Perhaps you’re on the fence over shrink fit vs. hydraulic toolholders. Or maybe your shop still uses Weldon side-lock holders and wonders why tool life is less than spectacular, or struggles with pull-out no matter how hard you tighten that collet chuck. You’re not alone. Many shops are using the same toolholder technology they started out with decades ago and are reluctant to invest in something new, or are confused over which direction they should go.
