What are the key specifications of Tungaloy DNMG110408-TM turning inserts?
The Tungaloy DNMG110408-TM turning insert (MPN 6772258) is a diamond-shaped indexable insert with an 11 mm inscribed circle, 04 mm thickness, and 08 mm nose radius. The TM chipbreaker is designed for medium to finishing cuts on steel and stainless steel. It is typically used in turning operations and is compatible with standard DNMG tool holders. The insert is made from carbide with a coating suitable for general-purpose machining.
How do Tungaloy trigon milling inserts like WPMW06X415ZPR AH140 differ from standard inserts?
Tungaloy trigon milling inserts, such as the WPMW06X415ZPR AH140 (MPN 6820780), have a trigon (W-shaped) geometry with six cutting edges, offering higher edge utilization compared to square or round inserts. The AH140 grade is a PVD-coated carbide designed for high-speed machining of steels and cast irons, providing good wear resistance and edge toughness. The 06 size indicates a 6 mm inscribed circle, and the 415 designation refers to thickness and corner radius.
What is the purpose of Tungaloy exchangeable slotting and slitting cutters?
Tungaloy exchangeable slotting and slitting cutters (e.g., MPN 6859487) are used for cutting grooves, slots, and parting operations in metalworking. They feature replaceable cutting heads that can be swapped without removing the tool holder from the machine, reducing setup time. These cutters are designed for use on milling machines and lathes, and are available in various widths and diameters to accommodate different slot dimensions.
Are Tungaloy inserts compatible with other manufacturers' tool holders?
Yes, Tungaloy inserts are manufactured to industry-standard geometries (e.g., DNMG, CNMG, CCGT) that conform to ISO and ANSI specifications. This means they are generally interchangeable with tool holders from other reputable brands that accept the same insert shape, size, and clamping mechanism. However, always verify the insert pocket dimensions and screw thread specifications to ensure proper fit and performance.
What materials are Tungaloy AH120 and AH140 grades suitable for?
Tungaloy AH120 and AH140 are PVD-coated carbide grades. AH120 is optimized for machining stainless steels and high-temperature alloys, offering resistance to built-up edge and thermal cracking. AH140 is designed for general-purpose machining of steels and cast irons, providing a balance of wear resistance and toughness. Both grades are used in turning and milling applications where surface finish and tool life are critical.
How can I identify the correct Tungaloy screw for my indexable cutting tool?
Tungaloy screws (e.g., MPN 6802580) are specific to the insert and tool holder design. The screw type is determined by the insert's clamping mechanism—typically a flat-head or Torx drive screw. Refer to the tool holder's documentation or the insert's specifications to match the screw's thread size, length, and head style. Using the correct screw ensures secure clamping and prevents insert movement during machining.
