EDGE² DTB Insert Grade Selection
Shock & Wear Resistance | Uncoated (Base Grade) | with Coating | Description | Specifications |
---|---|---|---|---|
TOUGHEST Shock Resistance |
DMK30 | Moderate wear resistance/high shock resistance. Recommended for interrupted or unstable steel, most stainless steel, high-temperature alloys and cast iron applications. | ANSI C1-C2, ISO K25-K40, M25-M35 |
|
DMK30-TCI | High-performance medium- to high-temperature grade. Outstanding shock and wear resistance in steels, irons and stainless steels. Best suited for materials < 44 Rc. | |||
DMK30-GLH | Premium high-temperature coating. Best resistance to heat for high-shock applications. Excellent for tough stainless steels, high-temperature alloys and many tool steels. | |||
DMK30-TS | General-purpose grade for most materials except hardened steel. Tough and wear-resistant, with all-around coating. | |||
DMK30-HM | Same tough carbide substrate, but with a higher-temperature coating. Usually used for high-temperature alloys or tough stainless steels. | |||
MEDIUM Shock and Wear | DMP25 | High wear resistance/moderate shock resistance. Recommended for most steel and ductile iron applications. | ANSI C5-C6, ISO P25-P40 |
|
DMP25-TCI | High-performance medium- to high-temperature grade. Outstanding wear resistance in steels and ductile. Best suited for materials < 44 Rc. | |||
DMP25-GLH | Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as higher-speed machining in steels (< 44 Rc) and ductile irons. | |||
DMP25-TS | Use TS for high-performance milling of steels and ductile irons. | |||
DMP25-HM | Use HM for high-performance milling of tougher steels and tool steels. | |||
HARDEST Wear Resistance |
DMK15 | Highest wear resistance with reduced shock absorption capabilities. Micro-grain carbide provides excellent edge strength. Suitable for all materials under stable conditions. | ANSI C2-C3, ISO K15-K25, M15-M25 |
|
DMK15-TCI | High-performance medium- to high-temperature grade. Great for higher-speed gray iron applications and lighter cuts in steels <52 Rc or ductile iron. | |||
DMK15-GLH | Premium high-temperature grade for optimum wear resistance in cast irons and steel hard milling > 44 Rc. | |||
DMK15-TS | Use TS for good all-around performance in harder steels and ductile irons. | |||
DMK15-HM | Use HM for the highest hardness in gray and ductile irons, as well as heat-treated steels. |
