Drill bit Life:
There are a few simple ways to extend the life of your drill bits that when followed will increase both the life and performance of any drill bit quite considerably.
- To extend drill bit life always run drill bits and drills at correct operating speeds, as a rule of thumb remember the bigger the diameter of the bit the slower the drilling speed.
- Use a Cutting fluid or oil, a quality cuting fluid keeps bits lubricated and reduces heat andcan double the amount of holes you can drill with one bit.
- Let the drill bit do the cutting at its pace and dont try to force it through.
- Drill a pilot hole, when Using larger diameter bits above 8mm it is a good idea to drill a pilot (small) hole first this smaller hole should be at least 50% smaller than the larger bit to stor binding and will allow the larger bit to drill more efficiently.
