Optimization of Serrated End Mills for Reduced Cutting Energy and Higher Stability

Abstract AISI Type M7 is a molybdenum type of high-speed steel. It is somewhat similar to AISI Type M1 tool steel but with higher percentages of carbon and vanadium to provide an improvement over AISI Type M1 in cutting characteristics without a significant loss in toughness. It is suitable for a wide variety of cutting-tool applications where improved resistance to abrasion is required. The many uses of Type M7 include twist drills, end mills, shear blades, punches, milling cutters, lathe tools, taps and reamers. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-483. Producer or source: Tool steel mills. See also Alloy Digest TS-468, January 1987.

Machining Operations

Abstract CPM REX 25 is a super high-speed steel made without cobalt. It is comparable to AISI Type T15 cobalt-containing high-speed steel in response to heat treatment, properties, and tool performance. CPM REX 25 is recommended for machining operations requiring heavy cuts, high speeds and feeds, and difficult-to-machine materials of high hardness and abrasion resistance. Typical applications are boring tools, drills, gear cutters, punches, form tools, end mills and broaches. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-365. Producer or source: Crucible Materials Corporation.

Abstract TATMO V-N is an AISI Type M7 high-speed steel modified by alloy balancing and a nitrogen addition to develop superior hardness response in heat treatment. It is an excellent grade for many cutting-tool applications requiring an optimum balance of red hardness, edge toughness and wear resistance, such as drills, taps, end mills, reamers and milling cutters. Its combination of outstanding properties and high hardness makes Tatmo V-N a logical alternate for cobalt high-speed steels in many cutting-tool applications. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, and surface treatment.
