Who isn't familiar with the small but generally spiky, sharp and voluminous remnants of milling or drilling tools, which perform their day-to-day work with gentle force. The waste, also known as chippings, that inevitably accures when a new product is shaped from raw iron, is frequently called "pretty but sharp" at collection centers, and this is for good reason. But the grayish-blue shimmering remnants are not only a nuisance for unprotected hands. Due to their perfected flight characteristics, they make detection within a milling machine quite difficult. And finally, the drilling water ensures that the little devils end up in every nook and cranny.
