Machine overview

When you sign up, you can:

The Hammer A3 31 jointer planer is the middle one of the Hammer A3 series. It is slightly larger than its smaller brother, the A3 26, but quite a bit more powerful. It is only about 20% more expensive than the A3 26, making it an attractive upgrade. The Hammer A3 41 is the larger version of this machine.

Its motor is relatively powerful at 3000W, available in 400V and 230V versions, which is not the case for the A3 26. It has longer tables and a longer fence, but the capacity of the planer is still the same as its smaller brother. It is also possible to mount a mortiser to the side as a third function.

In its base form it comes with a 3-knife, quick-change, self-adjusting cutter block. This can be upgrade to a so-called ‘Silent-Power’ cutter block, which has spiral cutters and is — as the name suggests — much quieter. In this video you can see the difference in sound it makes.

The Silent-Power block has spiral cutters, which is actually 47 small blades lined up in a spiral form. These blades have four sharp sides, meaning you can simply unscrew them, turn them around 90 degrees and use the next sharp side. Another benefit of this is that when you nick the blade, you don’t have to resharpen the entire blade, just turn one small one.
