Dremel 420 Heavy Duty Cut-Off Wheels, 20 Rotary Tool Accessories with 24 mm Blade Diameter and 14 mm Cutting Depth for Cutting Brick, Metal, Marble, Plastic and other Hard Materials

Bought similar non-Dremel resin discs and they were hopeless and dangerous splitting constantly. Bought these and 1 cut through a nut (not just a straight through slice due to awkward access but a lot of cuts to slice off..no breaking, reduced in side by about half and no dangerous breaking. Very happy with them. Cost is more but really good value for money considering their performance. Used these in my tacx rotary tool.

Very good unlike the cheap ones you can buy on eBay these actually cut without breaking

Cut a piece of metal what was in the way of a job in a fiddly area. Dremel is underpowered but it gets there eventually.

I needed the cutting disc to cut off a thin stainless steel piece from my coffee machine. I was unsure it would cope, so I purchased a pack of 20.. In fact it cut it with the first disc, (albeit the entire disc was used). I would recommend this to a friend.

I bought these for my Dremel... I think I am a bit ham fisted and was shattering the discs which came with the Dremel every few minutes... These are much more suitable for my inexperienced, heavy handed technique... I have even managed to finish a job with one disc without it breaking or being worn down to needing replacement!

Have used these discs before, work well.

Discs fly apart under pressure so if you are cutting something harder don't use to much pressure just let the weight of the tool do the cutting or the disc snaps jn middle and fly off

Well worth the money very impressive cutting and hard wearing
