Marcrist drill set??

[kilty55]

montolit cutters on an angle grinder have been the best by far that i have used so far

i have used marcrist,365 drills and rotozip cutters all are good as well

We were using the sigma with no water, eating through 30mm marble with ease and no heating up. It was good and thick too!
We had 4 grinder/ polishers in action and dust everywhere, lol.
