Inserts

MAPAL offers a broad portfolio of ISO tools for milling operations. A new series of cutting materials has been developed especially for the milling of the whole bandwidth of cast iron grades – GJL, GJV and GJS.

Cast iron drilling has taken a significant step forward with an expanded insert range for new diameters in the high-speed Color Select P6005-WKK45C grade for Xtra·tec B401x point drills. These new inserts are available in diameters up to 1.50 in. (37.99 mm). With this expansion, the grade specially developed by Walter for machining cast iron can now be used to drill all holes from 0.47 to 1.50 in. (12 to 37.99 mm) in diameter at depths up to 7×Dc and holes from 0.71 to 1.02 in. (18 to 25.80 mm) in diameter at hole depths up to 10×Dc.

Kyocera’s new CA3-series CVD-coated carbide inserts are for turning cast iron. The CA3-series grades with new K-series chipbreakers have become powerful contenders for gray and nodular cast iron machining applications, according to the company.

WS40PM’s cobalt-rich substrate provides robust fatigue resistance and edge integrity, while the multiphase AlTiN-TiN PVD coating reduces tool wear, making it suitable for a range of high-temp steel alloys, austenitic and PH stainless steels, nickel-based superalloys such as Hastelloy and Nitronic, and titanium.

Kennametal is expanding its Mill 4 family with a new cutting tool, the Mill 4-11. Designed for smaller machining centers, the Mill 4-11 accommodates 40-taper CAT and BT, HSK 50 and similarly-sized spindles. Due to its free-cutting capabilities, it is ideal for successful metal removal in less-than-rigid setups and on light-duty machine tools, multitaskers and live-tool lathes.

Walter says it has unveiled a technology that promises to dramatically improve machining effectiveness. Called Tiger·tec Gold, it is the latest iteration of Walter’s successful line of Tiger·tec and Tiger·tec Silver coatings.
