Rhodius 125mm 3-Blade Diamond Disc System for Wall Chasers

For electricians this is a good albeit expensive blade. I've only used in on breeze so far which it eats up. I did use it in a 1200W wall chaser and it is a bit slow but does the job well. For red brick you will need a much more powerful one. 25mm oval conduit fits in perfectly. You will need to clean out the hoover much more often as all the chase goes into it. Definitely better an quicker than a standard wall chaser and sds to chisel out the middle. Can really comment on durability as it hasn't seen much action but it looks very well made and will go through concrete apparently!update:I now use a 1700W FERM 1009 wall chaser which works much better with this blade. Red brick and breeze no problem. Some of the cutting blades on the edges have gone so i have now put normal grider blades either side of it to keep it alive for a bit longer.
