FAQ HSS bi-metal 8% COBALT hole saw Ø 27 mm ERK42027
- What is the purpose of the variable set teeth on this hole saw?
- The variable set teeth help to reduce vibrations and limit heat build-up during cutting. This configuration also facilitates chip evacuation in thick or dense materials.
- What does the 4/6 teeth per inch (TPI) specification mean?
- The number of teeth per inch defines the cutting progression. A 4/6 TPI variable tooth pattern provides an optimal balance between drilling speed and bore edge finish.
- Why is the 8% cobalt content important for this model?
- The addition of 8% cobalt to the HSS alloy increases the hardness and thermal resistance of the tool. This characteristic significantly improves the service life of the saw when machining tough metals or stainless steels.
