Dry cores tested on grade 5 porcs.


Got 32 holes in the 12mm dry core, one hole after the other, no stopping & still life left in it.

Can't fault them, just as good if not better than some blades I've paid 4 times the price for.

Just received from ATS

2 x 18mm, 2 x 35mm M14 dry corers

4 x 6mm waxed drill bits

And a porcelain turbo blade 115mm

The blade is awesome, straight cut and no chipping on the window checks.

18mm for fast fix shower fittings to go round 15mm copper, well impressed.

And the 35mm for radiator, hot/cold supply pipes and basin waste, finished off with a chrome plastic collar, all holes quick and clean through Hillock 600 x 300 porcelain from CTD.

Will report on the drilling tomorrow with the 6mm.

Would of rather had the 6mm M14 but mixed reports on longevity.

I'm not at all surprised you are impressed. Don't forget to share some pics if you get a chance [emoji106]

We brought the wax filled bits in specifically to cover the smaller M14 drills.

The M14 at 6mm we've found hit or miss in porcelain only and seems to be completely user dependent. We're more confident with the wax filled bits for the smaller holes.

115mm Turbo Flange Porcelain Blades are now out of stock but we have some in production we we hope to see within a couple of weeks.

Not really looking forward to drilling the 6mm holes as all my battery guns have seen better days and the 240v is SDS and with the chuck converter I'm nearly outside the room with the total length of it or need someone to hold a guide, you'll need to get the lab guys working overtime to come up with a perfect m14 [emoji12]

So this was us drilling with the waxed 6mm

3 minutes for this hole and over 5 for the next, I didn't try another with this bit.

The next bit was about 1.30 for the first hole then it didn't seem to go anywhere on the second hole.

Hikes done with XRP battery gun and 240v drill both on highest speed

I found it really awkward to try and hold a plywood guide and generally the sucker guides are unpredictable, fall off the wall and could cause damage so ended up piloting them with Bosch masonry bit (which goes through same tile in 1.30)

Overall fairly disappointed as I was expecting these to make life easier which is far from the case

On average between 15-20 holes fitting out a bathroom so even if it meant 2 or 3 M14 grinder 6mm for a bathroom I don't see £25-40 a job being a problem as I can hold and drill accurately with the grinder without a guide by myself instead of someone holding a guide for me or having to ware money on masonry bits to pilot first.

There's your problem.

The DeWalt XRP is at 2000rpm at full chat, not sure what speed your 240v drill operates at without the spec.

The wax filled bits are designed for drilling at 500-1200 rpm and you can't lean on them like you're drilling with a masonry bit.

The part of your video where all the smoke appeared, that was the point at which you burnt all the diamond off the tip with a combination of too much speed and too much pressure. Take it slow, let the diamond do the work and these will happily drill loads of holes and reasonably quickly.

The following is the spec on our website for these bits:-

Wax filled vacuum brazed dry porcelain drill bits.
The Hex shaft makes these perfect for use in a battery drill driver.
Can comfortably drill 20 or more holes in the hardest grade 5 porcelain.
Allow the drill and the rotation to cut the hole, don't lean on these bits like you would a masonry drill.
Never use the hammer action it will destroy the diamond tip. Use at around 500 - 1200rpm.
Available in 6mm, 7mm & 8mm the most common problem sizes. We tested larger sizes but found the cores got stuck in the wax. If you need to drill larger holes dry, see our M14 Vacuum Brazed bits which are available up to 65mm diameter.

When I spoke to your colleague on the phone last Wednesday about how to use them use he was quite specific in telling me the faster the better as the wax would melt more when I asked what speed to drill at....

The M14 bits are designed for 11,000rpm, the faster the better.

The wax filled bits are slow speed.

here is the bit after use as I've worked with all sorts of types of these kind of bits and seen the diamond leave the tip, this doesn't look like that has happened?

 

[trustiling]

I tried to order the m14 bits and was advised against!! So when I called to find out why I then enquired as what to do with the waxed bits and was told to drill fast

Difficult to see as the image is out of focus.

Why don't we send you a couple of new ones so you can try them at the correct speed?
