Perceuse à percussion rotative Mastercraft, 12 A

Works great ……………………………

Mastercraft SDS+ 12A Rotary Hammer Drill is awesome! (There i9s a typo in their name above). I guess I must have been living under a rock for 20 years or so, as the SDS drill holder is new to me. My other drills and hammer drills all have traditional chucks to hold the bit. SDS is a quick in/out holder and t bits have slots at their machine end that apparently aid in the transfer of the hammer action to the bit. This machine is about 12-lbs but it is easy to handle since it has the rear D-handle and the forward side handle that can be positioned as you need. There are two controls to set up drilling with no hammering, drilling with hammering, or hammering with no drilling. The latter is used for demolition with a chisel bit. I bought the Mastercraft SDS+ to drill a 7/8" hole at an angle through a concrete floor; the bit is a Diablo 18"er and had an SDS-plus end, so I needed a drill with an SDS-plus bit holder. For me the choice was between this machine and a Bosch that was longer and lighter but seemed like it might be more awkward to handle (plus it was more $$). At first I was not sure if the machine was hammering, so I tested it outside on a patio stone that is due o be replaced anyway. All those people burning up their hammer drills trying to o chiseling should look at the Mastercraft SDS+. It is as good as I hoped it would be. It's top-end RPM is lower but it has tonnes of power. The bit makes a difference. I think for my job a cross head would have been faster and would have been half the price than the Diablo, but I had limited options available in-town. There was very little vibration as this has cushioning for the D handle. We'll be using the chisel mode in the summer to renew our porch. I expect this tool to last a long time as it seems to be well-built, precise and with durability in mind. This style of machine is becoming more popular. I do not like battery tools
