Also, take it easy. Cut a shallow channel along the length and then slowly make it deeper. i.e. do not plunge the disk through the material to cut full depth for the whole length – Cutting full depth is quicker but it eats disks.

I get through hundreds of 1mm discs , like jaCK says above ,if you want speed plunge it , if you want disc life drag it back towards you .. I found the Screwfix discs ok .

Avoid Silverline from the Saturday market stall if you want disc life !

A trial on youtube

i once bough some that seemed cheap from a market. turned out to be the dearest ones i ever had. wore out very quick. i stick with branded ones now

Hi John, you could always try these or similar, but they do cost a bob or two more than a standard type of disc Norton Multi-Materiel Cutting

We used standard type Tyrolit make Tyrolit and Dronco make Dronco in my last day job that I had and they always faired very well.

Regards Nick.

Spring steel is a hard tough alloy and it's going to put up a fight! Use the right type of blade for the material and don't expect magic – the blades are sacrificial. They're made of tiny sharp crystals held together in a matrix and the crystals are ripped off as soon as they are blunted allowing fresh ones to attack the job.

I'm not sure what the best blade for spring steel would be. Definitely not the types of blade sold for stone cutting and Aluminium etc. I guess most of the ordinary blades sold for Ferrous metal are aimed at the softer structural steels rather than performance steels. A blade made to cut stainless steel might be good for this.

Keep an eye on the cost – may be cheaper to use several ordinary blades rather than the best one.

Always good to know how things work out – can you report back please? What you tried and how well did it do?

Hi,, I’ve always used 1mm thick 4.5mm discs bought from markets or autojumbles, I’ve got Bluespot at the moment .

Ive cut all types of ferrous metal including stainless ,upto 10mm thick. Never had a problem . I use a Bosch mains grinder never tried a battery type. Let the tool do the work and take your time.

..and another for Tyrolit..

Is that really your name John, or just for the Forum?

Then you do a really careful shallow first cut the full length of the job, marking out will obviously help a lot

Those early cuts can be made with the job clamped up fully in a vice

After that guiding cut has been made the rest of the job is just careful common sense, don't hurry it for best results
