FAQ HSS BI-METAL COBALT 8% hole saw Ø 25 mm DIAG650D25
- What is the purpose of a 4/6 TPI tooth pattern on this type of hole saw?
- The variable pitch 4/6 TPI teeth help reduce vibrations and optimise swarf evacuation. This configuration is ideal for achieving stable and efficient cutting in ferrous and non-ferrous metals.
- Why is the choice of an 8% Cobalt HSS alloy important?
- The addition of 8% cobalt increases the tool's hot hardness and resistance to abrasive wear. This ensures greater durability when drilling tough materials compared to standard high-speed steel.
- What precautions should be taken with the set milled teeth?
- The set teeth increase the width of the cut to reduce lateral friction of the hole saw body against the material. It is recommended to maintain an appropriate rotational speed to avoid excessive overheating that could alter the tooth geometry.
