FAQ HSS Bi-Metal 8% Cobalt Hole Saw Ø 20 mm ERK42020
- What is the effect of the 4/6 TPI variable pitch tooth pattern on the cut?
- The variable pitch tooth pattern limits vibrations and improves chip evacuation during drilling. This configuration allows for a smoother cut and a reduction in mechanical stress on the hole saw.
- What are the advantages of the 8% Cobalt HSS composition for this tool?
- The addition of 8% cobalt significantly increases the hot hardness and wear resistance of the tool. This material is particularly recommended for drilling tough metals or alloy steels compared to standard HSS steel.
- How can I optimise the service life of this hole saw during use?
- To preserve the geometry of the set teeth, it is advisable to adapt the rotational speed to the 20 mm diameter and the type of material being machined. The use of a suitable cutting lubricant is essential to reduce heat build-up and ensure edge retention.
