– Maintenance and repair works:
different applications, e.g. opening augmentation

Grade drills have, as the name suggests, different degrees that cut out the desired diameter and the same differ from other types of drills.
They enable one instrument to produce holes of different diameters.

For HSS step rigs as coolant or grease
Apply sanding oil, oil for drilling and cutting or compressed air. For HSS rig without coating, the use of coolant is required.
