Milling Cutters

DoMini-Mill is a copy mill developed for semifinishing operations, featuring Tungaloy’s latest H-class insert. The economical six-cornered insert with dovetail clamp technology has a double-sided geometry, yet positive flanks, providing sharpness and high cutting edge strength simultaneously.

DoForce-Tri from Tungaloy America accepts a double-sided insert with six cutting edges. Three types of inserts are available to meet the needs of many different jobs: a standard wiper insert with an MJ chipbreaker on true 90-degree cutting edges or with an NMJ chipbreaker on serrated cutting edges, as well as a radius insert with an MJ chipbreaker on large round corners for edge toughness instead of wipers.

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.

The new MC341 Supreme carbide shoulder/slot milling cutter from Walter is specially designed for extended tool life when machining steel and stainless steels. According to the company, yhe cutter delivers exceptional tool life, plus performance improvements of up to 100 percent thanks to the innovative new Walter WK40TZ grade, a special proprietary coating process and added design enhancements as well.

Back in 2014, Kennametal announced a technology partnership with Haimer for the development of a modular cutting tooling system. Since that time, the company has been busy developing, testing, and building inventory of DUO-LOCK, which promised even then to be “the most rigid and most precise interface in the marketplace.”
Today it’s even better.

MK Tools solid-carbide round tools from Monaghan Tooling Group introduces new "Speed-Drill R4" geometry, reportedly offering unparalleled cutting speeds and unprecedented tool life when cutting gray cast iron, ductile iron and forged steel, which are popular materials in automotive engine and chassis components. With a new corner radius design which is tangential to the drill point but nontangential to the diameter, these proven designs address challenging, high production drilling applications.

Walter has introduced its new Prototyp Advance line of solid-carbide milling tools for universal application. The new Advance milling cutter line consisting of six cutter types and 250 line items, each reportedly providing the ideal balance of hardness and toughness for the widest possible application, plus long tool life (increases of up to 50 percent) thanks to the Advance line’s new high-performance WJ30TF grade and Walter’s TiAIN coating.
