I’ve got a makita wall chaser. What is the best one. Mainly 20mm chases.
The triple blade is indeed excellent. I factor in a new triple blade every 3 rewires, not always required but they can be rock hard bricks that eat them quicker.Pretty much every downstairs wall here is floated out in plaster. I've comfortably chased 25mm round conduit to a good depth with the Metabo. Worth mentioning the triple blade is a bit slower than most folks would be used to with a twin blade, but worth every extra moment when it leaves a nice clean chase ready for cables.
I bought a Parkside chaser from Lidl to do a one-off job. Works a treat and only cost me £80. Appreciate if you chase walls a lot (I don't) then a Metabo or Dewalt is going to last a lot longer but think - I can buy 5 or 6 Parkside chasers for the price of one. Food for thought....
