or anyone who owns, operates, or manages a machining center, these are exciting times. Never before has there been such an awesome assortment of high-quality cut- ting tools. Newfangled toolpath algorithms are removing


metal like there’s no tomorrow. Toolholders grip tighter and more accurately, vises and fi xtures can be swapped out in the blink of an eye. If your shop isn’t taking advantage of all the industry has to offer, the one thing you can be sure of cutting is profi t margin. Here are some new tooling developments together with a few best practices to think about while you watch the spindles go round.


The Right Tool for the Job


It seems simple. Hole drilling operations are best done with a drill, face milling should always be performed with a face mill. But many shops see great success using center cutting end mills to drill holes, albeit shallow ones. Why bother with a face mill when a shoulder mill is handy? And what’s wrong with using that old standby, the two-fl ute, 1/2" (12.7-mm) solid carbide end mill, to cut everything within reach?
