Cutting a neat chase in British brick and block sounds simple until dust fills the house, the discs stall, and the channel is too narrow for conduit. Go too light and you will struggle in hard masonry; go too heavy and overhead runs become exhausting. The trick is balancing raw power, dust control, and precise depth and width adjustment for clean, patch-ready grooves.

Buyer Questions and Expert Answers
What depth and width do I need for UK electrical and plumbing chases?
For a single 2.5mm twin-and-earth cable in oval conduit, aim for around 20-25mm wide and 25mm deep. For 20mm round conduit or central heating pipes, you will typically need 30-40mm wide and 30-40mm deep. Choose a chaser with tool-free depth and width adjustment so you can cut once to the right size, leaving just enough cover for plaster (usually 10mm+ over conduit) without weakening the wall.
Do I need a dust extractor, or can I just cut dry?
You need a capable extractor for indoor work. Wall chasers generate extreme fine silica dust from brick, block and concrete. Use an M-class extractor with a tight-fitting hose, keep the shroud flat to the wall, and cut in a steady push motion. Shake or pulse the filter regularly. For very dusty concrete, a water-feed option or pre-scoring plus extractor gives the cleanest result and protects motor and lungs.
Will these wall chasers cut concrete, engineering brick and block?
Yes, with correct diamond discs and technique, but hardness matters. Lightweight block and plaster chase quickly with any of the three. Medium brick and concrete need constant speed and patience — let the discs do the work, avoid forcing, and clear the core with an SDS chisel. Very hard engineering brick or reinforced concrete will be slower and wear discs faster; take shallow passes and allow cool-down time.
Is a 2-disc or 5-blade setup better?
A standard 2-disc setup with spacers is lighter, easier to control, and ideal for neat electrical chases — you knock out the centre. A 5-blade system removes more material in one pass and can cut wider pipe chases faster, but it is heavier, draws more current, and strains harder in dense brick. If you mainly chase cables, 2-disc precision wins; if you regularly chase wide runs for pipes, multi-blade flexibility helps.
What safety and UK site essentials should I check before buying?
Check voltage: 240V is standard for home DIY, while many UK sites require 110V — these picks are 220-240V models for home and workshop use. Always use eye, ear, FFP3 dust mask and glove protection, plus RCD protection. Confirm disc size (125mm is widely stocked in the UK), arbor size, and that spacers and flanges are included. Never use without the guard, never grind sideways with chase discs, and check for hidden cables and pipes with a detector first.
