Inserts & Tool Bits

A new power skiving solution composed of CoroMill 178 and CoroMill 180 cutters from Sandvik Coromant is being released to help automotive manufacturers complete gear and spline components in one setup on a multitask machine or machining center. Skiving processes are many times faster than shaping and more flexible than broaching, and are quickly becoming an efficient and flexible alternative for gear and spline production.

Kyocera Precision Tools has expanded the popular CA025P CVD-coated carbide series for steel turning to include all new positive insert styles. The next-generation CA025P series features multilayer CVD coatings with a layer using a thick film of aluminum oxide (Al2O3) for excellent heat resistance.

Shops that struggle to manage metalworking chips and optimize tool life in extreme turning applications will benefit from the new Seco -R3 and -RR93 insert geometries. As part of the RCMX and RCMT range of turning inserts, the new geometries make easy work of such challenging applications as turning railway car wheels.

With the introduction of 13 new full-profile threading inserts, Seco Tools now offers a full range of UNJ and MJ thread profiles for both external and internal applications. Shops that need to generate high-precision threads in stainless steels and heat-resistant nickel-based and titanium alloys will benefit from the extremely tight-tolerance profiles of these inserts.

Tungaloy's new T9225 insert grade is joining the earlier successes of T9125 to complement the T9200 CVD grade series for steel turning. T9225 brings an exceptional combination of unparalleled wear resistance and top-notch edge toughness of all P25 grades available on the market to every steel turning application.

To eliminate the difficulties of hard turning operations, Seco Tools has added a new grade format and several new geometries to its already expansive line of PCBN inserts. These additions broaden the extremely tough Seco CH3515 insert grade and introduce a new solid CBN150 insert grade, special long and short wiper geometries and laser-etched chipbreakers.

Walter has expanded its Tiger·tec Gold line of indexable inserts with the addition of the WMP45G grade made specifically to handle the challenges of turbine blade machining. The new WMP45G grade, available as round indexable inserts for the F2334R copy milling cutter, is for facemilling and copy milling of martensitic and austenitic stainless steels.

To eliminate long face milling cycle times and ensure process security, Seco Tools has introduced new larger LP09 inserts for the company's HighFeed 2 cutter bodies. The new inserts are designed for high-feed milling operations including face, helical interpolation, slotting, side milling, pocketing and plunging, in challenging workpieces often found in the mold and die, aerospace, and oil and gas industries.

The Walter Cut MX grooving inserts deliver high levels of flatness and surface quality with their tangentially-mounted arrangement in the G3011/G3021 holders. Four cutting edges per insert multiply user productivity and, if one cutting edge breaks, the other cutting edges remain usable.

The Pramet T8010 is suitable for continuous precision threading of steels, stainless steel, cast iron and superalloys. It further extends our assortment in this application area and supports the universal grade T8030.

Dormer Pramet's latest milling grades - M4303 and M4310 - provide durability and reliability in semifinishing and finishing applications.

Cutting tool and tooling systems specialist Sandvik Coromant is launching GC4330 and GC4340, two new insert grades for steel milling. With the development of advanced production technologies, such as a new substrate, Inveio coating and an improved post-treatment technology, the new grades provide great opportunities to substantially increase tool life and process security compared to the previous generation of grades, GC4230 and GC4240, which will now be superseded.
