External mitre profiling tool

[Concrete guy]

^ very similar indeed but on the bullnose and radius tools I prefer to use a stainless steel guide. This mitre tool will have a plastic guide like the images above.

These are vacuum brazed diamond tools so will work wet or dry. Wet will last longer.

The big advantage of vacuum brazed is they don't lose their shape with wear and they don't drop diamonds, so it's ideal technology for this kind of tool that is creating a uniform shape.

Factory drawings are back. I've ordered 10 to start us off to see how you guys like them.

We have the option to manufacture these in one of 3 grit levels.

Coarse - 40/50 grit (the image of the r10 tool above is 40/50).
Medium - 70/80
Fine - 140/180

As this isn't a finished edge that's seen we've decided to go with coarse which will give the fastest and long lasting tool of all three. We can always alter that with later production of we need to but we think it will provide the best tool for purpose.

The cost will be £68.15 + vat (£81.78) + P&P - I will ship international at cost if required.

We're likely to see these within the next 4 weeks.

If you have an interest in one of these first 10 then let me know and we'll earmark one for you.

I'll post images on this thread when they arrive.

I'll take one
. should i PM you? can i pay now ? :hurray:

We can organise all that when they get here Tony, your name is on the list so you have one of the first in reserved.

For lowish value items of this nature I'm not overly keen on taking money off people until I actually have the items sat in front of me.

If someone is ordering 500 off I want see some cash!

Reserved list (including anyone who expressed an interest earlier in the thread).

It looks like I need to up the order already.

If you want to add your name simply copy this post - add it on and post.

Same if you want off the list.

Thanks for that . You see i have criticized MITRE WIZZ heavily, as didn't see nothink serious. What you have here , could be the tool which sits in most tilers tool box

That would be good. It's odd little items like this that often surprise us.

Quick - register the design. Patent it. Do summink! :smilewinkgrin:

Perhaps I'm missing something here but the principle of both is broadly the same - a hand held tool for mitres.

Both look to be good options.

MITRE WIZZ IS ACTUAL ANGE GRINDER, in video clip they cut mitre , i believe on ceramic tile (wich is soft) . With mitre wizz you don't see what you are doing, does it fit on any angle grinder? etc. etc.etc. I just realy want to try this new tool 🙂 , i think it has potential. It's only my opinion

 

[One Day]

The age-old trouble with cutting mitres on tiles - particularly porcelain - is the jagged edges.
Mitre-wizz as far as I can tell, doesn't address that bit of the problem.
This tool though would leave a nice clean 1mm "lip" of either factory-edge, or our wet-cut edge.

This tool definitely has the potential to be better as I would think the cut itself would be better than a grinder blade cut, it appears that the cut itself would be obscured from view by the tool itself.

Is this new tool designed to be used dry with a grinder?

Yes it's designed for use on a grinder wet or dry (wet will extend tool life). The only thing I'm not absolutely sure on right now is the target cutting speed.

I've assumed it will be close to the marble bullnose tools we sell at under 4500. But I have a feeling that porcelain actually might benefit from high speed cutting/grinding so that may even open up the tool use more if were able to be used at say 10,000rpm on your average grinder.

I've come from a stone background so have a limited knowledge of profiling porcelain, but I will confirm target speed before the items are sent out.

i have vacuum brazed drills for dry and wet use for a variable speed grinder. i prefer diamant drills in wet use but sometimes i don´t have my hole drilling machine by me. so the vacuum brazed works perfekt in marble and granit but on porcelain stoneware it works not smooth and if you don´t use it wet theres no long life. so i will try your tool, cause i can use it for natural stone by the way. but i personaly would prefer a big coating of diamant, only wet use and adjustable rings when shape is smaller.


in this video on 6.28min you see the bullnose tool on porcelain stoneware.

The problem with diamant (sintered or metal bonded diamond) is as the tool wears by design the shape of the profile changes.

The metal section is designed to wear away to expose the diamond and keep the tool sharp, it's exactly how cutting blades work and as you know they wear.

So vacuum brazed is a better product for a profile tool that has to retain it's shape permanently.

As you point out, it will work wet or dry. We would expect an extended life span if used wet. What is yet to be determined is if the finish is improved hen used wet vs dry.

The monolit tool is vacuum brazed and interestingly they are using it at high speed on a standard grinder.

 

[Concrete guy]

Having a had a chat with the engineers at the factory we've decided to make these profilers to a 30/45# grit which will cope far better cutting porcelain dry.

Vacuum brazed tools can withstand very high temperatures, so the target speed for these tools will be anywhere between 4500 - 12000 rpm. That means they can be used on a regular angle grinder.

There's no set target speed as such as the material (rather than the tool itself) will determine the most appropriate speed.

So on a new job, with a new tile, just run it on an off cut first to see how it's cutting and if a speed adjustment is required.

We have some other stock on it's way in 10-12 days times and these profilers will ship with them so we should have these available in less than 3 weeks time.

 

[Concrete guy]

The factory has said the mitre tools will be ready in 2-3 days. By the time they have shipped they will be with us towards the end of next week (week beginning 12th November.)

Nice one Alan,

Give Lee @ protilers one to test run, we can all watch the vid then and you may well get inundated with orders!

I sent Lee an R10 half bullnose and 20mm full bullnose this week. First thing he asked was "Where's the mitre bit?". LOL

Lee, it's not here yet.

 

[Concrete guy]

The Profilers arrived today.

But, (there's always a but isn't there!) There is a small inexpensive but very important piece missing - the guide washer in between the cutting head and the plastic guide. This will run along the 1mm good edge of the work piece and stop the tool cutting too deep.

I'm getting some run up so they can be fitted.

Of course the tool could still be used by simply clamping a batten to the tile and using the plastic guide as a depth stop as the appropriate size.

I'd prefer to have the complete and correct before any go out though.

Overall I'm pretty happy with how they've come out from an idea only a few weeks ago.

I'll update as soon as I have a solution for the depth stop and will then be able to send the first ones out.

I'M waiting :drool5::hurray:

 

[Peter]

Looking good. Could have used it last week, the DW250 is hopeless at mitres.

Frustrating waiting for them, all I need are a few washers and they are ready to go.

It's a new item, it's worrying if it turns up without at least one minor teething issue or you think you've forgotten something!

 

[Alan.P]

Nice, waiting patiently.

how much longer ? when are we gettin new mitre mizz? :incazzato: :lol:

 

[Concrete guy]

Probably have them ready to go first week of December.

We had to re make some components and I don't want these going out until they are right, they will operate at around 10,000rpm so need to be spot on. I figure we're still safely on target to get out before the mitre whiz :smilewinkgrin:

Looking forward to the test results.......but may jump on the bandwagon too and pop myself on the list!

Update. All the modified parts arrived for the tools yesterday. I assembled three and all looks good. However I can't send anything out without a good test.

So we ran one of the first today on a regular grinder and on a speed variable dry flex. So far with a 10mm Limestone tile and 10mm Marble tile.

It cut perfectly, in limestone and marble, dry (at slow and fast speeds) right down to the last 1mm then there was breakout and chipping on the edge.

Basically I've had the guide washer made 1mm too small so it allows the cutting head to cut very slightly too deep.

So the good news is, it works! The bad news is, I need another set of guide washers run up before I can send the first ones out.

I've also yet to run it on Porcelain and we've yet to try it wet. Dry we had it running at full speed on a dry flex machine on the marble and the finish was good.

So sorry, there's a further delay, but I'll update once the next batch of washers arrive.

Getting there Alan, keep us updated.

Just checked in to see the progress, I like your style in not wanting to send out the tool until it's 100% .............. cheers 🙂
