FAQ HSS Bi-metal cobalt 8% hole saw Ø 21 mm ERK42021
- What is the purpose of a 4/6 TPI tooth design on this tool?
- The variable 4/6 teeth per inch design helps to reduce vibrations and optimise swarf removal during cutting. This configuration ensures better stability and a cleaner finish in metal materials.
- Why is the choice of an 8% HSS Cobalt alloy crucial?
- The inclusion of 8% cobalt in the HSS matrix reinforces the heat hardness and abrasion resistance of the teeth. This maintains increased cutting efficiency on tough materials while extending the tool's service life.
- What precautions should be taken when using this hole saw?
- To ensure optimal longevity, it is recommended to use a rotation speed suitable for the material's hardness and to apply constant pressure without forcing. The use of a suitable cutting lubricant is advised to limit tooth overheating.
