Hello guys, a bit of advice on purchasing core bits.
In your experience what are the best/ most cost effective core bits to get?
I've been using my mates rothenberger ones and they are pretty good, but expensive. I've seen some at toolstation called mexco and they seem reasonably prices, although they still cost more than a ton for a full set.
Are they much of a muchness or is there a real difference in the build quality?
I am sick of pilot drilling every hole then braying the "Sugar" out of it with a bolster.
AdamsHeating,
I would like to tell you that the more you pay the better they get but I have not found that to be the case.
Buy yourself a cheap set and replace the ones you use most with more expensive single ones.
The most important thing is to have a decent drill with clutch, don't even try using the larger diameter core bits with a drill without a clutch - you'll end up badly damaged!

I bought both my tungsten and diamond core bits from the place that is heavily advertised on this site, and some I have had for over 5 years and still work.
Sometimes tungsten cores work better if the brick is soft. They cut like butter in my SDS Kango thingy.
If the brick is hard, then diamond is better, but the core drill I have , the clutch is a bit sharp, and if it jams, either I go round, or the house turns over, Lol.
You need different speeds for tungsten and diamond. T, less than 1000rpm, D, about 1500rpm.
Screwfix do a couple of ranges and both are good. Bearing in mind Screwfix are primarily a trade supplier the top of the range stuff can seem veryt expensive to an enthusiiast but the middle of the road DIY stuff is certainly Ok and we use it all the time.
