Rush Machinery’s drill and tool grinders can lower hole-making costs through higher precision, faster production, less downtime and reduced tool inventory, the company says.

The grinders combine simplicity, accuracy, rapid setup and versatility in one machine to allow the user to choose from a variety of HSS or carbide drill points to maximize drilling performance for varied applications. With minimal setup change, stepdrills, taps, reamers, countersinks and end mill ends can also be ground. The machines grind almost any point, stepdrills, taps, reamers, end mills and countersinks (HSS or carbide). In addition, the standard workhead can be exchanged in less than a minute with an optional air-bearing attachment for end mill O.D. grinding.

Machines are available from manual bench top to automatic-infeed floor models with capacities of 0.080” to 1 1/4”, 3/32” to 2”, and 3/16” to 3 1/8”.
