I purchased the 152mm to ensure there was plenty of space for adjustment and slight fall on the soil pipe. This was a great size as there was plenty of space for the 92.5° Double Socket Branch. I would recommend having a powerful mains SDS drill (mine was 1500w), no hammer used I think that would damage the teeth. The dimond core performance was great and cut through the brick relatively easily. It left a clean hole and the cores were easy to get out. I also purchased the 13mm x 200mm Starrett guild bit and arbor. I would purchase other sizes in the range if required. Recommended.

J'utilise cette scie à trous pour couper le béton dur avec du métal et elle a fait le travail exactement comme il se doit
