Marcrist Core Drill Bit Set & Dust Extraction Unit 9 Piece Set is rated 3.5 out of 5 by 13.
Rated 5 out of 5 by from Very good Very good core cutting set especially with he dust extraction would definitely recommend, as other reviewers disappointed that there was not a pilot bit.

Rated 5 out of 5 by from Retired DIY'r Managed to cut 2 x 127mm cores in a double skin cavity wall with a core drill I bought in addition to the kit. Disappointed that the taper fit pilot drill was not included, nor could I find it in the Screwfix catalogue, in the end I had to buy it online from another supplier. Dust extraction system worked well. Found my drill was not man enough to cut the 127mm core and ended up buying the Marcrist drill, again from Screwfix. OK so I'm a diy'r and probably will not get the value out of the equipment I bought, but I had the huge satisfaction of drilling two (what I thought to be) massive 127mm core holes.

Rated 4 out of 5 by from Excellent core bits! I am so far happy with this product. My only bother was that they didn't come with a tapered drill bit for the centre??? There is so many other core bits out there that do come with them. I assumed it would of come with one considering the price..

Rated 3 out of 5 by from Good cores, but part missing? I never noticed when buying these core bits BUT there is no pilot drill bit supplied??? Kind of makes them a bit useless you buy the extra bit. Yes, half my fault for not reading the small print but when the 'the cheaper' Titan rival includes it (which I've had for a number of years) it's making me question things. This is the second set I've had from Screwfix as the case handler fell off as I pull it out the cardboard box after leaving the store. I did try the small bit without a pilot (which is not advisable) and it did the job cleanly...but I'm still a bit disappointed I've to search and pay for an extra bit after buying the drill to match.

Rated 1 out of 5 by from Very poor drill bit I bought this to core out a waste through a wall it burned out before getting through the first brick so got a replacement which lost a tooth after 5 minutes, so decided to take that back and got a cheap Erbauer one which did the job with ease. Over priced diy rubbish.

Rated 4 out of 5 by from Marchrist Core Drill Kit Cores are of a higher quality as to be expected with the higher price tag. The kit is relatively new so can't comment on the durability of the bits. One thing to be aware of is that it does not come with a guide bit, rendering the kit useless until you buy one at extra cost. It's a shame when this kit is basically 150% more expensive that cheaper brands yet they all come with guides..?

Rated 1 out of 5 by from Verry disappointing Im a professional builder and I have purchased this set although it's quite expensive but was hoping the brand will guarantee quality. How disappointed I was when after one hole in concrete footing I was out of two cores!!!! Not worth the money

Rated 4 out of 5 by from The best Bought these as tired of use using cheap bits that the teeth turrets fall off of within 5 uses. Quality bit of kit in a neat box.
