NEW HOLEMAKING INSERTS BOOST PRODUCTIVITY LONGEVITY

The innovative Beyond? platform of high-performance tool grades from Kennametal (Latrobe, PA) has garnered exceptional reviews from customers worldwide. Now the company is introducing the first Beyond inserts for holemaking applications. Three new grades are available: KCPK10, KCU25 and KCU40. The product portfolio covers SPPX/SPGX Drill Fix Square (DFS?) outboard inserts, which are available in HP, FP and MD geometries.

Kennametal?s DFS indexable drill platform offers the economy of a square insert having four edges in the outside pocket combined with the outstanding centering and high feed ability of a DFT trigon insert. The DFS indexable drill can be used in virtually any short-hole applications and materials performed on CNC lathes or machining centers.

Achieving up to 20-percent or higher material removal rate (MRR) at the same tool life as standard inserts, the KCPK10 grade offers outstanding abrasion and crater-wear resistance for high-speed machining of steels and cast irons. Combined with a 30-percent extended tool life, KCU25 is the first choice for processes at high speeds and feeds, delivering very good reliability in steels, stainless steels and cast irons.

With a multi-layered PVD TiN-TiAlN coating and a tough substrate, the KCU40 grade delivers double the tool life at equivalent material removal rates for standard inserts. This grade withstands interruptions and provides high wear resistance for long tool life.

?Three new Beyond grades cover holemaking in steel, stainless steel and cast iron, and provide outstanding results both in highly stable, high-speed conditions and difficult, unstable jobs,? says Thilo Mueller, senior product manager. ?With four high-productivity cutting edges where they are needed, the DFS drills with new Beyond inserts enable higher speeds and, as there is simply more tool body material between these two inboard and outboard inserts, higher feed rates than competitive tooling based on squared inserts only.

?By using a trigon-shaped insert inside, we simply have more material in-between, and the tool does not become fragile as does tooling with squared inserts only. This feed advantage, plus chip flutes that enable much better chip evacuation, gives users better hole quality at higher MRR ? a real competitive advantage.?
