do not buy cheap aftermarket blades, i bought a bosch when i moved into my flat and it was a lifesaver for doing skirting, sockets and removing gummy adhesive residue from concrete floors and got a new blade for removing more adhesive and the spot welds failed as soon as i turned it on, sending a triangular pice of sharp metal whizzing past my face, had safety glasses on but could have had an unwanted funky new piercing.
