Walter has introduced the D4120, an indexable insert drill, (with up to 5 x Dc) that combines superior performance, enhanced precision and cost-effectiveness due to Walter’s technological advancements.
The drill’s list of features begins with a design that facilitates easy chip removal, process reliability and close hole tolerance through hardened and polished flute surfaces. Good finished surface quality and hole tolerance is achieved through a wiper cutting edge on the periphery insert, optimized chip flute design with continuous chip evacuation, as well as a coolant-through system (one per cutting edge) for improved cooling and fast chip removal.
Cutting costs are kept lower because of four cutting edges and the long tool life characteristics provided by Tiger·tec Silver grades. The versatile D4120, which employs inserts from the P484 family, is suitable for ISO material groups P, M, K, N, S in all major industries.
Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.
Metal-removing edge on the face of a cutter that travels in a plane perpendicular to the axis. It is the edge that sweeps the machined surface. The flat should be as wide as the feed per revolution of the cutter. This allows any given insert to wipe the entire workpiece surface and impart a fine surface finish at a high feed rate.
The drills are coolant-through, straight flute (G-drills), with emulsion or oil and coolant pressure of 145-580 PSI (10-40 bar). They are offered in cylindrical shank configuration and have a 120° point angle with tolerance of m7. They are also offered in L/D ratio of 5 x Dc as standard, with…
The MD173 Supreme is a roughing cutter designed specifically for dynamic milling and for reducing machining time. Its cutting edges equipped with chip breakers enable excellent chip breaking, permitting superior process reliability with high metal removal rates, a plus for users with automated…
A patent-pending, highly textured, multi-layered MT-TiCN layer increases toughness and reduces flank face wear, resulting in lower cost per cutting edge. The inserts’ highly textured Al2O3 layer also minimizes crater wear, and the gold-colored top layer improves wear detection. The gradient carbide…
This grade is now capable of longer tool life, greater reliability, and approximately 30 percent greater performance in stainless steels (ISO M) and heat-resistant super alloys (ISO S), and up to 75 percent greater performance in steels (ISO P) than comparable grades. With the launch phase now…
These new vibration-free tools provide finish machining of precise bores (IT6–IT8) up to 6 × D, with high surface quality and are up to three times more reliable and flexible than comparable models. Their flexibility is boosted by the fact that the new Walter boring tools employ modular components…
With the TC630 Supreme, users can benefit from a range of advantages. A high level of process reliability for unstable machining operations, for example on lathes with driven tools or for long overhangs. Areas of application include medical engineering, precision engineering, the aerospace sector…
Walter has introduced the Xtra·tec® XT M5460, a new profile milling cutter that delivers maximum precision, tool life, and surface quality in precise machining of freeform surfaces and deep cavities.
These indexable turning inserts are designed for applications where a soft cut and high precision is required. Long tool life is achieved through the WEP10C coated cermet grade with multilayer PVD TiCN TiAlN coating and extra fine cermet substrate grain. Walter's combination of edge…
The WNN15 grade delivers outstanding process reliability and long tool life, even at extremely high cutting speeds. This means that it makes indexable insert drilling more cost-effective than comparable PCD tools with immediate effect. The indexable insert drills offer the advantage of multiple…
