Kennametal is introducing new high-performance HSS-E-PM (powder metal) Beyond™ taps for large-diameter tapping. Target applications for the new tools include some of the most essential wind turbine components such as hubs, rings, and gearbox housings.

With a highly wear-resistant powder metal substrate and proprietary top layers and coatings, the new Beyond™ HSS-E taps provide superior performance in  tapping steel components such as gear rings and mainshafts; or for tapping cast-iron components such as hubs, housing, and gear boxes. The taps are available in sizes from M24 to M42.

Designed for both conventional non-rigid and CNC-synchronous tapping machines, precision h6 shanks enable use in either conventional tap holders with square drive or in precision round toolholders. Wind energy component suppliers will want to note an extra-long version is available to reach the longer overhangs  common on these large components.

“Unlike other choices on the market, the addition of these large size taps with our KSEM Plus modular drilling program provide a complete solution to drill and finish the hole,” says Marcelo Campos, Senior Global Product Manager, Tapping at Kennametal. “Where most other large-size taps are specials, we’re providing a broad standard range of differentiated designs and coatings for increased speeds and better tool life across a wide spectrum of applications.”
