Dry Diamond Holesaws - Vacuum Brazed M14 fitting.

[Concrete guy]

We've introduced a new range of Vacuum Brazed Dry Diamond Holesaws with M14 fitment to attach directly to angle grinders. Very similar to the Rubi dry core range or the Marcrist PG750X-M14 range.

We don't see these as a replacement for electroplated holesaws, rather a product that runs along side and solves that problem when there is simply no option to drill wet. Or you may simply prefer to use these as opposed to the electroplated bits.

These are designed to fit directly onto the thread of a grinder/polisher and will operate at 10,000 rpm plus on any standard 115mm or 125mm grinder.

They will also work on variable speed grinders and Wet polishers.

Each bit is hollow even the 6mm size, so if you have a wet centre feed machine like a Flex polisher you can utilise the water flow. It's unlikely this will speed up the cutting or even create a cleaner hole, but it will extend the drill bit life maybe as much doubling useable lifespan.

50mm in length they will cut through pretty much anything including 30mm thick granite counter tops.

The range is currently limited to the 12 sizes shown below which represent our top 12 selling sizes in electroplated holesaws. We can make pretty any size though if there's an obvious yawing gap in there somewhere.

Any questions just ask.

price list?

Nice and shiny

price list?

I have to be careful how and what I post - I'm not a full forum sponsor (I have a support account here) so blatant direct advertising, links to websites and sales elsewhere are frowned upon, understandably.

If you search for my user name on Google I'm pretty easy to find.

From £12.24 inc vat for the 6mm up to £49.20 inc for the 65mm.

Good work, some nice products lately. Prices are spot on too. How many holes would you expect from these in run of the mill porcelain?

We'd be disappointed if these were producing less than 30 holes completely dry in grade 5 porcelain, which is on a par with the Marcrist bits. I've not found a spec on the Rubi cores that suggests how long they last so I can't really give a comparison.

We have a few more new items coming early February mainly aimed at masons with some grinding drums and polishing pads specifically designed for engineered stone (quartz).

But we do also have a 125mm dished blade for grinder fitment with a large "T" diamond segment that will be of more general interest for cutting curves and radius in tile and stone.

Have you any plans to offer "Tilers starter kits" ???

Or, any freebies for trial purposes you understand.

What do you think would make up a tilers kit?

My business partner is always suggesting we do prepacked kits in much the same way 365Drills do but I'm not sure I see the value in that at the prices we offer. Selling individually gives you the option to put together exactly what you want.

With kits I always get the feeling we'd be putting one or two items/sizes in there that were not going to be used.

We do occasionally have forum offers, but like I said above, TilersForums have been very generous in allowing me to post and I'm conscious of upsetting the people who pay to be here. I have to tread carefully.

Polishing drums are handy, I use a reamer for widening out holes too.

Interesting, I didn't consider it a "tiler tool".

I've got three sizes in production this month, all M14 fitment. 20mm finger bit, 50mm diameter drum and 75mm diameter drum.

Technically I'd consider these grinding drums rather than polishing, but the fine grade would certainly remove the need for two steps of polishing pad.

Each in three different grades of vacuum brazed diamond.

30/40 = coarse
70/80 = medium
140/180 = fine

Wouldn't want a pre made kit myself, prefer to buy singles as and when rather than buy 2 sizes that won't be used.

I'm with you on that front. The kits just look like a marketing exercise to me.

My business partner is the marketing genius so I guess that fits!

There's times when I'm fitting marble shower trays the trap doesn't fit in the hole !!
We then use a reamer (30mm finger) to just run around the hole to widen it a bit, works a treat but no polishing needed as the lip on trap covers the hole edges.

The thing is Joe, you're kind of cross between a stonemason and a tiler. Most tilers wouldn't be reaming out a marble shower tray waste!

Mostly these drums are used for flush fit hobs or undermount polished sink cut outs in the granite business.

It never fails to astonish me what use we sell products for. I sold a 60mm holesaw this morning to a specialist boat yard for cutting holes in boat hulls for sonar equipment. It seems electroplated holesaws are perfect for fibreglass and provide very clean holes.
