In fact solid carbide tooling is typically 85 or 90 tungsten carbide particles in a matrix of 10 or 15 cobalt to hold them together.

Ideally tool steels would contain as much carbide volume as needed for the desired wear performance.
Compare grades using mechanical properties including abrasion resistance toughness size stability machinability and grindability.
M4 is the designation in both the sae and aisi systems for this material.
The high carbon content enables m4 steel to be hardened in excess of 65hrc.
A large volume of vanadium carbides provides the high wear resistance.
The high impact toughness and high transverse bend strength are results of the fine grain.
At those levels it achieves a good balance of strength and ductility.

The properties of sae aisi m4 steel include two common variations.
Griggs steel color code.
However the high hardness and high vanadium carbide content make it more difficult to grind after heat treatment compared to m2 and other high speed steels.
Chemically the microscopic carbide.
Cpm rex m4 hc high speed steel is an extremely versatile high speed steel that provides a unique combination of high wear resistance with high impact toughness and transverse bend strength.
A2 tool steel is an air hardening cold work chromium alloy die steel that is preferable to o1 tool steel in applications requiring greater size stability machinability and safer hardening.
The wear resistance properties and cost place a2 between that of o1 and d2 tool steel making it a good all purpose grade for many applications.
