How to use

Designed to be used dry for drilling at high speed.

Start to drill at a 45 degree angle and level up once the bit was taken hold then for a faster and cleaner cut rotate and oscillate whilst drilling, do not apply undue pressure on the angle grinder / drill, allow the diamond and speed of cut to do the work as too much pressure will shorten the lifespan of the core bits.

If drilling a number of holes together, it will increase the lifespan and help the core bit to work better if you can dip the bit in water to help keep it cool in between drilling.
