Inserts

Sandvik Coromant recently introduced a new endmill for small diameters, the CoroMill 390 with size 07 inserts is said to be a versatile cutter ideal for shoulder milling, deep shoulder milling, edging, linear and helical ramping, plunge milling, slot milling and face milling, according to the company.

Seco, Troy, Mich., recently expanded the roughing and semi-finishing performance capabilities of its Secomax CS100 sialon ceramic grade inserts by adding inserts with T-style edge preparation to the line, according to a company news release. Featuring a free-cutting, sharp geometry, the new inserts are said to bring strength, stability and performance longevity to the machining of nickel-based superalloys in unstable conditions.  

THINBIT, manufactured by Kaiser Tool Co., announces the expansion of its GROOVE ’N TURN line of dovetail grooving inserts. Dovetail grooving inserts are used to machine O-ring dovetail grooves with 66° undercut angles.

For longitudinal and face turning, Sandvik Coromant introduces the CoroTurn 300 for higher component quality, increased handling efficiency and longer tool life in steel turning operations. The CoroTurn 300 features stable insert clamping, as well as eight-edged inserts for the high chip control, tool life and surface finish.

Truly indexable finishing inserts have arrived with the new EDGE² spherical ballnose (SBN) system from DAPRA Corp. SBN inserts feature two usable cutting edges, delivering cost savings and high-quality finishes.

EHWA Diamond Industrial Ltd. offers its VT series of PCBN (polycrystalline boron nitride) indexable cutting tools. With the VT line of inserts, end users can achieve deeper depths of cut given the more robust method of cutting edge construction versus the industry standard brazed chip-style insert, according to the company.

Greenleaf Corp.’s XSYTIN-1 is a phase-toughened ceramic insert grade that resists wear and thermal shock. It is for milling, turning and grooving heat-resistant superalloys, cast iron, nodular iron, ductile iron, steel and stainless steel at extreme feed rates and high cutting speeds, according to the company. It is suitable for interrupted cuts, scale removal, roughing, semifinishing and finishing.

Rani Tool Corp. offers German-made PCD inserts with CB3 chipbreakers from Becker Diamond Tools. The chipbreaker has a semiserrated wave profile on the flanks of the cutting point, which increases the material-removal rate and produces short, controlled chips. The inserts are suitable for machining with flood coolant or minimal-quantity lubrication.

SwiftCARB offers a complete line of straight-shank and shell-mill indexable-insert corner rounders. According to the company, the tools increase cutting speeds and feed rates by 25 percent, and the tools’ inserts can be changed quickly, which enhances efficiency. The company stocks more than 70 radii, from 0.010" to 1" and from 1mm to 25mm.

Kyocera Precision Tools Inc. says positive-style inserts with its WP chipbreaker and a wiper cutting edge impart fine surface finishes at low cutting forces. The chipbreaker stabilizes chip conditions at low feed rates, controls excess chip breaking during high-feed and high-load machining and prevents tearing of the finished surface by controlling adhesion. The inserts are for machining steel and stainless steel and are available in a variety of CVD- and PVD-coated grades.
