Milling inserts
Our range of milling inserts: get ready to be amazed
Are you looking for one partner for the supply of all your milling inserts? Sharp Metal is the company for you: we’re able to design and produce inserts for finishing, roughing and medium machining operations during the milling phase.
Our wide product range is the result of collaboration between a network of European users and our technical department. This has allowed companies from the most diverse mechanical sectors, carefully selected by us, to help us understand users’ real needs. In this way, we’ve created a line of products that overcome the limitations of inserts produced until now, offering top-quality practical solutions.

Selecting the material
When developing the milling inserts we supply at Sharp Metal, our specialists start off by selecting the material to be machined.
Each material has different chemical and physical properties that meet certain requirements better than others. For this reason, we’ve created inserts with specific grades, classifying the different materials to be machined according to their ISO families:
- Steel;
- Stainless steel;
- Cast iron;
- Non-ferrous materials;
- Hardened materials;
- Superalloys.

Selecting the machining operation
The second stage when creating a successful line of high-quality products for milling involves selecting the desired machining operation. This step is essential in reducing the margin of error and guaranteeing precise and exact application.
To ensure we make the right choice, we’ve broken down all machining operations into three groups (finishing, medium machining and roughing), allocating certain geometries and hardnesses to each one.
| OPERATION | GEOMETRY | ISO HARDNESS |
|---|---|---|
| Finish | F | 20 |
| Medium machining | M | 30 |
| Roughing | R | 40 |
Selecting the coating
A final step influencing the choice of the most suitable insert to be made is that of the coating. We’ve collaborated closely with our suppliers on this to select the most suitable coatings to be used depending on the material to be machined. Our partners have state-of-the-art PVD and CVD coating technologies that are vital during this stage.

Cutting strategies
Not all inserts are the same. The inserts in our product range meet specific needs. But how can you find out what needs those are?
We encourage you to check the “Q” parameter, or chip removal rate. This quantifies the chips produced by machining in a set time period. Calculating this value is important, as it would be a mistake to focus on cutting speed to determine a machine’s performance.
