Quicker pit stop

The main factors for boosting productivity in machining tend to concern the tool itself, but tool handling is also important. Walter AG takes on board both of these approaches with its new Xtra▪tec® Insert Drills with Walter Capto™ clamping.

Drills with indexable inserts are talented all-rounders and can be used for cutting a variety of materials ranging from steel and cast iron through to stainless and difficult-to-cut materials. Chain drilling, sloping or convex surfaces? No problem! Walter has enhanced its Xtra▪tec® Insert Drill family: It now has modular shanks with Walter Capto™ clamping and indexable inserts with Tiger·tec Silver®. The advantages for the user are, on the one hand, faster tool changing and, on the other, higher transmission of force via the polygonal Walter Capto™ interface.

"The high-performance Tiger·tec Silver® cutting tool material improves the performance of the new drill," explains Manvinder Singh Saini, Product Manager for Indexable Drills at Walter AG in Tübingen. "The indexable inserts have four genuine cutting edges, enable high cutting parameters and help reduce the number of additional operations necessary. The ground indexable inserts are also fitted with a wiper edge, which means that they ensure excellent hole surface finish."

High process reliability is ensured by the positive locking of the indexable inserts with TorxPlus screws.

An overview of the Walter Xtra▪tec® Insert Drill, now with Walter Capto™ clamping:
