Dremel type cutting discs

[Ron LadenParticipant @ronladen17547]

Any recommendations for Dremel type cutting discs that have reasonable life and are good value for money. The ones I have at the moment cut well but their size reduces faster than what they are cutting.

Around 25 – 30mm would be good though not critical, dont have to be genuine Dremel as long as they do the job.

Drexel are the only ones that do the job

There are two types (at least) of Dremel cutting discs. The 1" dia ones with the small screw retaining them do a great job but as you say Ron they wear fast. However the second type are 1 1/2" dia and fit on Dremel's E Z Lock mandrel. The metal cutting ones are fibre mesh reinforced and last much longer. One drawback though is that they wobble a tiny bit on the mandrel and are thicker than the smaller disks, so the cut width is larger. Link below shows these at a Canadian retailer's website. I am sure you can get them in UK at a Dremel distributor.

The next step up is the 1 mm thick cut disks for 4 1/2" angle grinders. You can do some serious damage fast with one of those!

You could switch to diamond discs.

I use the small 1" diameter discs. The trick is not to push them very hard . They are after all grinding the material away. I used one disc to cut the length of a 3" Burrell chimney made from 1.2mm sheet steel and still had some left at the end ( small some !)

You need to use the highest speed and a light cut so the motor doesn't slow down too much. I have used various makes to cut nuts and exhaust U bolts under cars where there is no room for an angle grinder. Colin

I use the Dremel ezlock and have no trouble with wobble and they have a good life if not pressed hard. The smaller discs are brittle and I find they break before they wear, ok for cutting small diameters.

Try the dental technician suppliers. They have a vast range of disks and all sorts of handy cutters and burrs.

Thanks guys I have ordered the Dremel speedclick mandrel and 5 discs I will see how I get on with those.

Hi, these Cutting Discs or these More Cutting Discs may interest you. (not sure if Amazon links are allowed though)

Hi Ron –

I appreciate you have one solution but I bought a pack of 85 of the ordinary disks from a high street tool and machinery dealer at about 10p a disk – They do wear down and can break, but they are cheap enough for me to cope with that.

[Ron LadenParticipant @ronladen17547]

Thanks guys,

Nick the ones I have are probably similar to your pack of 85 they came as part of a set I bought years ago but had not tried them until yesterday. I ran at 30,000 rpm and I am not heavy handed but I reduced the disc by more than half its diameter in reducing the length of thread on 8 x 6BA screws. I guess as part of a set they are probably the bottom end of quality but didn't quite expect them to be that bad. I will see what the Dremel ones perform like and report back.

[Ron LadenParticipant @ronladen17547]

The Dremel Speedclick mandrel and discs arrived and a quick test proved them to be very good, much better than what I have been using. A bit of an acid test more than what I would do with small discs but I cut through a 10mm round piece of EN8 and the disc reduced by just 0.6 mm, more than happy with that.

[Nick WheelerParticipant @nickwheeler]

You can get reinforced similar to the Speedclic ones, but without the proprietary fitting. They last almost as long, but are a lot cheaper.

I find that Dremels are one of those tools that seem like a good idea, but are not much use in practice. Especially if you're using them on steel.
