On Porcelain tiles about 40 holes per pack (10 holes per drill bit) on the SMALL cores at 6mm and 8mm
PLUS... The drills dont just blow like a lightbulb on hole ten.
You can get more life out of them it just takes longer to drill the holes. On average about another 5 holes per drill bit is the total lifespan on HARDEST porcelain tiles taking it up to near 15
ABOUT 40 TO 60 HOLES PER PACK on the small cores.
(10 TO 15 HOLES PER DRILL)
Remember to drill slowly, use water and dont push the drills.
On Granite you can double the number of holes to about 80 per pack.
On Soft Ceramic tiles you can expect 100 holes per drill bit.
On soft ceramics 100 holes per drill bit is easily achievable simply because
there is no work for the diamond holesaw to do. Once you break the
glaze then the drill hits the powder soft clay behind and takes the hole
out in seconds. And with perfect results on Porcelain & Ceramics.
Under test conditions at:
The bigger core drills
At least twenty holes per drill at the larger sizes (more diamonds - longer life)
