Lost my Angle Grinder virginity!

Aug 01, 2010 10 Replies

Needed to trim back the slates along the edge of the roof by an inch after removing the rendering on the wall below. Bought a Wickes 1000W



125mm AG, does the businness but it is eating stone cutting discs (non diamond). I bought three thinking that would be one and two spares...

I'm about to use the last one. I've cut about six linear metres of approximately 5 mm thick roofing slate, mostly double with the some triple thickness. The lower layers I'm not cutting right through just making a score and snapping off.



Is that rate of disc use about right or am I doing something wrong?


Aldi, cheap diamond sets. Finish isn't terrific, but they cut and last pretty well.

The rate of disc uses sounds suspiciously low! Probably becasue real slate is quite soft and does not wear discs at the rate of concrete etc.

However, treat yourself to a diamond blade and marvel at the difference in longevity and performance!

Get yourself a diamond. Even low end ones outlast many many grit discs, and they perform better, and are safer.

Thanks guys, I just about managed to finish what I needed to do before the last disc was worn out and that was doing even more score and break that I had previously.

Well thats what I thought as well in only buying 3 discs to start with. If I'd been cutting through brick or real stone I'd have probably bought some diamond blades as brick/stone is 'ard compared to slate init...

I will now! Unless you are cutting something really soft, like mortar, I can't see abrasive discs being any use at all.

AIUI diamond discs wear faster with soft materials. I still use grits at times, diamond isnt best for everything, especially on HSS.

Couldn't you have just put a wooden batten under the gutter brackets? I'd have thought the further out you could take the water, the better.

Gutter? This is along the tops of a gable. B-)

Barge boards would be used on most buildings but anything that the wind can even remotely get behind will be ripped off(*)... Slates trimed to just proud of the rubble stone wall and mortared over.

(*) We get 40 to 50 mph sustained winds at ground level and there is a considerable difference between exposed ground level and chimney level, as I had found in the last few days. I wouldn't be surprised if wind speeds at chimney height can be 50 to 60mph sustained, with gusts 10 to 20 mph above that...

I also would suggest Aldi, cheap and cheerful but it works. I bought mine to cut up thick church paving slabs followed by tree roots still in the ground!

Lost my angle grinder virginity on the living room floor of my first house, in 1987.

Fit a wind turbine.. then the winds will drop.
