FAQ HSS bi-metal cobalt 8% hole saw Ø 30 mm ERK42030
- What is the purpose of the 4/6 TPI variable set tooth geometry on this hole saw?
- The 4/6 teeth per inch variable pitch reduces vibrations and heat buildup during drilling. This configuration is designed to provide better chip evacuation and smoother penetration in metal materials.
- Is the 8% cobalt alloy suitable for tough materials?
- Yes, the incorporation of 8% cobalt into the HSS bi-metal composition improves hot hardness and tool wear resistance. This feature is particularly recommended for machining alloy steels and high-strength metals.
- What precautions should be taken to ensure the longevity of this bi-metal tool?
- To preserve the teeth and limit wear, it is advisable to use a suitable lubricant during cutting. Adjusting the rotational speed according to the 30 mm diameter is essential to prevent premature overheating of the alloy.
