SXEH 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 300 series stainless steel, high- temperature alloys and cast iron applications. ANSI C1-C2, ISO K25-K40, M25-M35
DMK303 PVD TiCN coating. Excellent wear resistance for low-to-medium operating temperatures.
DMK30-HP High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons.
DMK307 PVD AlTiN coating. For higher-temperature applications including tougher stainless steels, high-temperature alloys, high-speed machining and heat-treated materials.
DMK30-GLH Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys.
MEDIUM
Shock and Wear
DMP25 High wear resistance/moderate shock resistance, recommended for most steel and 400 series stainless steel applications. ANSI C5-C6, ISO P25-P40
DMP253 PVD TiCN coating. Excellent wear resistance for low-to-medium operating temperatures.
DMP25-HP High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons.
DMP257 PVD AlTiN coating. For higher-temperature applications including high-speed machining and heat-treated materials.
DMP25-GLH Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys.
HARDEST
Wear Resistance
DMK15 Highest wear resistance with reduced shock absorption capabilities. Micro-grain carbide provides excellent edge strength for abrasive applications in nonferrous materials. Suitable for castings, aluminum and smoother cuts in tough stainless steels, high-temperature alloys and hardened steel. ANSI C2-C3, ISO K15-K25, M15-M25
DMK153 PVD TiCN coating. Excellent wear resistance for low-to-medium operating temperatures. Good resistance to built-up edge for aluminum machining.
DMK15-HP High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons.
DMK157 PVD AlTiN coating. Appropriate for higher-temperature applications such as high-velocity cast iron machining, tough stainless steels, high-temperature alloys and hardened steel.
DMK15-GLH Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys.

DMP25-HP is a good first choice for most applications. Additional coatings available on request. Contact Dapra for details.
