Cutting Tools & Tooling

By combining high clamping force and optimized interference levels, Kennametal says its new KM4X100 provides a robust connection, extremely high stiffness, and bending load capacity for greatly improved performance in machining high-strength alloys and other materials.

Nexus Cutting Tools introduces its SNKX high-feed insert.

Sumitomo Electric Carbide Inc. has expanded is best-selling AC400K Series for cast iron turning to include new finishing and general-purpose grades.

Sandvik Coromant introduces GC4325, a new-generation coated cemented-carbide grade for steel turning.

Experienced manufacturers know that when milling, three main considerations predominate: metal removal rate, tool life, and surface finish. All three are critical to successful metalworking, but often one will predominate. Manufacturers facing parts requiring 90-degree shoulders also know that achieving true 90-degree shoulders and minimizing the scallop or step marks between passes absolutely requires a high-performance cutter. The new Mill 4-15 platform from Kennametal is that best-in-class system, according to the company.

Advanced hard turning, or the use of superhard polycrystalline cubic boron nitride (PCBN) cutting tools for machining hardened ferrous materials like cast irons, is eagerly sought across a number of key manufacturing industries. Hundreds of millions of brakes discs, brake drums, flywheels, and wheel hubs are required annually in motor vehicle, heavy equipment, and other industries, and although superhard tools show promise for turning such tough-to-machine parts, that promise has been stalled due to the tendency of these expensive tools to shatter and break under the extreme forces required. With decades of experience in advanced materials science and tool design, Kennametal is announcing Beyond Shield as the solution (responding to modern challenges in machining cast iron machining) to this situation.

EXSYS Tool Inc.'s new PRECI-FLEX Compensating Clutch system for Nakamura CNC turning centers enables users to "float" away misalignment between turret drive motors and toolholders, leading to smoother operation, finer surface finishes and longer tool life.

Allen Benjamin Inc. has introduced a line of high performance, application-specific HSSE spiral-flute pipe taps.

Coherent Inc. has expanded its family of industrial ultrafast lasers with the Talisker HE series, whose high energy pulses reportedly enable drilling, cutting and scribing of thicker materials than with other ultrafast lasers.

A portable pneumatic saw with a pipe trolley system for accurately square cutting ductile iron concrete lined pipe from 6" to 60" in diameter is available from ESCO Tool.

J.W. Winco Inc. offers series GN 334 Aluminum Oval Tubular Handles, in inch and metric sizes.

Walter USA LLC has announced a series of new insert geometries for turning that bring higher levels of productivity to a range of difficult applications.
