Features :
- Titanium coated surface can reduce friction and overheat when drilling through the material for a longer lifetime
- Two-flute design provides faster, smoother and accurate cutting
- 1/4" hex shank (6.35mm)can be easily fit into power driver, drill and press drill
- Used to cut holes in a variety of material like thin steel & iron, wood, aluminum alloy, insulation boards, PVC sheet, Concrete.
Νοte:
- Star drilling at low speed. Do not push too much. Let the drill bit to cut by itself. ¨
- The harder the material it is working with, the lower speed shall be applied.
- Inject coolant oil while working, it will dramatically increase the drilling efficiency and extend the drill bit lifetime
- Drill bits are good for wood, plastic, steel and sheet metal drilling. Stainless steel is not recommended.
