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 C5-C6,
ISO P35-P40,
M30-M40
  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.
  DMK30-IN Tough substrate combined with a new exotic-specific coating designed as the first choice for titanium. Very suitable for stainless steels and high-temperature alloys.
TOUGH
Shock and Wear
DMK35   Specifically developed for inconel and other high-temperature alloys, as well as demanding stainless steel applications. Also suitable for smoother general-purpose milling in a variety of materials. ANSI C5-C6,
ISO M30-M40,
P30-P40,
K30-K40
  DMK35-TS Use TS for general-purpose milling in a variety of steels or irons.
  DMK35-HM Use HM for a higher-temperature coating in tough stainless steels.
  DMK35-IN IN provides the best performance for high-temperature alloys and tough stainless steels. First choice for inconel.
MEDIUM
Shock and Wear
DMP25   High wear resistance/moderate shock resistance. Recommended for most steel and ductile iron applications. ANSI C5,
ISO P25-P35,
K25-K35
  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 K10-K30
  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.
