Best value for money thin slitting discs?

[gaz1]

Bosch
Bluespot tried dont like
Dronco used last a while
Flexovit
Parweld same as dronco
Tyrolit
The Klingspor ones I currently have were 64p per disc

Rhodius at a £1 a disc seem a little pricey same as dronco i got those as a freebie

its what made me upgrade from the bluspot cheaper discs

Dronco used last a while

Any ideas on what the difference is between Dronco Attack Discs & Perfect?

Seem reasonable prices in packs of 25

i was using the basic dronco discs

ive still got the 3mm discs and also the 6mm grinding discs they last a while rip metal off quickly

The old man has a stash of Klingspor 1mm that he said he pays 50p each for from our LWS - i'll go pay them a visit tomorrow morning as that's a proper bargain.

Tyrolir 3 Star 1MM are my favourite Cutting Discs. Let me know if you want a few sending over to try, I’ve got plenty. Can pop them in the post FOC.

Go for it Tom, I'd like to try those out...

Sooo.. how to devise a test for them, so we would actually know? Really I guess we are looking at longevity assuming all else is pretty much equal. Some sort of rig with a weight on a grinder and enough cuts to make a measurable difference?

One of the problems with the cheaper ones may be the same as welding rods that they are from different suppliers at different times, but it could still be worth while.

something like this with a weight on it would provide a test basis

These guys in Oz did a test on 4 types,

just with hand pressure but apparently got consistent repetitive results.

A test comparison would be good!

Been using Tyrolit and really decent.

We use these at work. Very good.

id love to do a test with these

got the camera to do it and easy enough to make that grinder holder for my grinder all it would need is a weight to simulate someone pushing on it

just let the grinder do its work

rebar would be the best way to test it as consistant size

I found that with the Lidl discs. The first batch had green writing on them & were ok but the ones I got most recently have blue & red writing on them & are very good. The colour & writing looks very similar to a Dronco disc, they are also a German company so they could have made them!

My Parweld ones arrived today, but it'll be a while before I need to start in on them, I was just stocking up - 42p each seemed a decent deal.

Best way to maintain a consistent cutting pressure for the test is with a digital power meter (a cheap plug-in type)

Make sure all competitive discs are produced around the same date for a fair result (refer to date stamp on steel centre ring) as there’s a three year shelf life on them, and they deteriorate with age (become softer).

Push too hard and you’ll wear the disc away too quickly, not enough pressure will dull the cutting edge and it will burn.

Familiar names (Bosch, Makita, Erbauer etc) have discs produced for them by a manufacturer to a budget - typically a very low one!

I’d recommend European/US manufactured discs (look for ANSI/EN12413 numbers) for safety.

Best value = cost/number of cuts/time.
