Inserts & Tool Bits

Dapra Corp.'s New EDGE2 double-sided DTB cutters and inserts feature twice the number of usable edges as single-sided button inserts for superior metal removal and value. These thick carbide inserts provide better heat and stress absorption, resulting in longer service life and increased strength, according to the company.

Akuma indexable carbide inserts from Travers Tool Co. inc. use advanced substrates, high-tech coating processes and progressive geometries to provide tools for today's demanding machining applications.

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.

Sandvik Coromant Co. says the GC4305-grade insert maximizes metal-removal rates, shortens processing times and enhances component quality when turning steel. It is made of a heat-resistant cutting material that is suitable for dry machining, which is ideal for automotive part manufacturers that seek to avoid the stresses tools experience as a result of temperature fluctuations. The insert features the company's wear-resistant Inveio coating.

Iscar Metals Inc. offers Heli IQ Mill inserts for numerous milling applications across a variety of industrial sectors. The three helical cutting edges reduce cutting forces and power consumption, according to the company. The inserts are now available in cermet for machining medium to hard materials, are peripherally ground for milling stainless steel, and are ground sharp and diamond-polished for cutting aluminum.
