Use of Tool Steel O1 CNC Cutting Tools
Tool steel O1 for cutting tools, CNC operations are favored in high-performance tooling applications such as:
| Punches and dies | Gauges |
| Shear blades | Forming tools |
| Engraving tools and knives |
The annealed O1 tool steel parts are especially useful when post-machining heat treatment is required, allowing for fine-tuning of the hardness and microstructure based on specific performance needs.
Machining Benefits: CNC Machining 1.2510 Tool Steel
What makes O1 Tool Steel a Good Choice for CNC Machining?
If you’re comparing O1 vs A2 tool steel CNC, O1 stands out for its better machinability and lower cost while still maintaining strong performance in cold working conditions. It offers:
- Outstanding response to heat treatment
- Reduced tool wear on cutting tools
- A decrease in the chances of cracking or distorting
- Clean and uniform surface finish on annealed O1
At MYT Machining, we offer CNC services tailored to the precise machining of CNC machining 1.2510 tool steel, ensuring tight tolerances, excellent tool life, and clean edges.
Thermal and Mechanical Attributes
Thermal Conductivity O1 Tool Steel Machining Advantages
O1 tool steel machining processes have the property of thermal conductivity, which enables the process to effectively lose heat and minimize overheating during cutting. This is essential in applications where fine edges and temperature-sensitive tolerances are significant.
- Thermal conductivity: -24.0 W/mK (at 100 o C)
- Hardness of annealed O1 steel: ~197 HB
- Depending on the application can be heat-treated to 62 HRC
These 100MnCrW4 machining properties make it ideal for wear-resistant tools and precision fixtures that demand toughness and edge retention.

FAQs About Tool Steel O1 | 1.2510 | 100MnCrW4 – Annealed State
1. What is the hardness of annealed O1 steel?
O1 tool steel is usually annealed to a hardness of 197 HB, and is then good as a machine and subsequently heat-treated.
2. What is O1 vs A2 tool steel on CNC?
They are both cold work steels, with O1 being easier to machine and grind, but with A2 being tougher, and thus harder to cut.
3. Can annealed O1 tool steel parts be heat-treated?
Yes. The annealed O1 steel is an excellent machining grade, and subsequently may be heat-treated to suit application up to ~62 HRC.
4. Can O1 have what surface finish?
The annealed O1 can be machined surface finish of a clean, smooth surface and particularly when incorporated as a fine ground surface or polished after machining.
5. What are the thermal properties of 100MnCrW4?
The grade is of good thermal conductivity and thus it can be used in processes that need effective heat generation the processes as cutting or forming (~24 W/m-K).
