■What is an HSS hole saw?
It is a hole saw that has a bimetallic structure employing cobalt HSS welded to cutting edges. Cutting edges with a narrow pitch are available for a wide range of work materials from wood to PVC and iron plates.
■Peripheral Speed
Common Steel | Aluminum |
---|---|
25-35 m/min | 30-50 m/min |
-
■Cobalt HSS Cutting Edge
High cutting performance is realized by welding cobalt HSS of the cutting edges to the strong spring steel body. The non-uniform arrangement of cutting edges eliminates vibration during drilling.
Non-uniformly arranged cutting edges are adopted for the HSS hole saws with diameters of 21 mm or more.
-
■Shavings Escape Hole
The escape hole, which is convenient for shavings removal, is equipped with HSS hole saws of all diameters.
Remove the main unit from the motor and insert the metal rod that fits through the hole, etc., through the shavings escape hole to push out debris.
-
■Safety Stopper
A safety stopper is provided to prevent removal during drill penetration.
- Securely chuck the three-surface section of the shank to prevent swinging or falling.
- Do not reduce the rotation speed excessively during drilling. Jamming or tip cracking may result.
- Do not hit the cutting edges against any hard object or allow strong contact with the work material that may occur when the center drill passes through. The tip will crack.
