Milling Tools and Gravers
Brief Description EW9 Co10
This high-speed steel with high hot hardness and abrasion resistance as well as remarkable durability can be used successfully in most machining situations for rough machining and finishing.
EW9 Co10 / 1.3207, precut or ground to a finish, is produced in large quantities and is therefore available quickly and in many forms and dimensions.
The dimensions specified in this information sheet at this grade are always stocked.
Considering the three selection criteria of price, performance, and availability, this grade has proven itself in most usage situations to be superior to other comparable alloys.
