FAQ HSS bi-metal cobalt 8% hole saw Ø 35 mm ERK42035
- What is the advantage of the 4/6 TPI variable set tooth design on this tool?
- The variable pitch tooth design helps reduce vibrations and harmonics during drilling. This configuration promotes optimal chip evacuation, ensuring smoother cutting in metallic materials.
- Why is the presence of 8% cobalt crucial when choosing this saw?
- The addition of 8% cobalt to the high-speed steel (HSS) composition significantly improves the hot hardness of the tool. This technical feature extends the life of the teeth when performing intensive drilling in alloyed materials.
- What precautions should be taken to optimise the service life of the hole saw?
- It is recommended to use a suitable cutting oil to limit tooth overheating and facilitate chip evacuation. Ensure that the rotation speed is adapted to the 35 mm diameter and the hardness of the material being worked to avoid browning of the cutting edges.
