Cutting Tools
Restarting A Program After Breaking A Tap
It's common to have to rerun tools. If you find a problem during the program verification with the eighth tool, for instance, you'll want to restart the program from the beginning of tool number eight rather than having to rerun the entire program just to get back to that point.

Read MoreOne Insert For More Operations
Conventional wisdom about standard milling operations has always been that compared to square shoulder cutters, lead angle cutters are easier on the spindle, can be run at higher table feed rates, and cut freer. Finishes are typically better and, with the addition of a wiper flat insert, finishes could be further improved. Due to the chip thinning attributes of this type of cutter, actual table feeds can be more rapid, albeit at the sacrifice of some depth of cut compared to a zero lead cutter.

Widening Range Of Grooving Tools
Traditionally, a grooving tool grooves, a facing tool faces and, of course, special tools do special cuts. Improved insert manufacturing technology and toolholder design is changing this tradition, allowing specialized tooling to be used more generically in a wider variety of metalcutting applications.
