The biggest of the Hammer tablesaws, this one offers a very solid well-specified performance without unnecessary frills. Yes, it takes up space, especially with the sliding table in the up position, but it can moved around using a wheelset and it doubles as a spindle moulder too.

It is robustly built from pressed steel and finished in a tough powder coating with a cast and ground table and an extruded aluminium sliding carriage.

Starting with the basics, the open-frame sliding table can be left off and the outrigger support folded away, making the unit more compact if you simply want to ripsaw or do spindle moulding.

Fence

The substantial extruded aluminium fence is clamped to a large heavy casting that slides along a machined steel rod at the front. Setting blade-to-fence distance is done by eye down the fence line onto a scale at the table front edge.

Saw blades from 250-315mm diameter are possible although you need the smaller size if you have the optional scoring unit mounted. The fence can be withdrawn to the front when using a rip blade and solid timber.

Apart from the blade rise-and-fall control the arbor can be tilted using the same handwheel. This is moved from one to the other by engaging on the control shaft.

Sliding table

The sliding table is fairly easy to fit to the side of the sliding carriage. It hooks into the side and is fixed by a couple of knobs. Although there is no set position for the table and the accompanying fence, the logical and continental way - which takes account of large panel cutting - is to have the fence at the front of the sliding table, then adjust the table position until you can successfully pass a full board width through the saw.

The fence allows easy dimensioning of small solid components as well as boards, using a flip-over length stop.

The sliding table itself runs very smoothly on a sophisticated bearing system but can be locked via a twist knob for rip operations.

Spindle moulding

For spindle moulding operations the standard fence is moved back and the spindle fence setup bolted in place over the spindle. The insert rings can then be popped out and a cutterblock installed on the shaft.

Standard work hold-down/guards are bolted to the lid of the cutterblock housing. The fences are aluminium extrusions with no allowance to fit wooden sub-fences.

Speed changing

Access to the pulleys to change the speed is via a door at the end of the cabinet. This has a safety interlock as does the access to the saw arbor via a slide lever and knob which locks off both functions when carrying out maintenance or changeovers.

Accessories are available with which to configure the machine to suit your specific needs.

On Test

This machine is a substantial lump but with a wheelset added it is perfectly possible to manoeuvre it around to maximise on working space. Although the sliding table is not too difficult to fit or remove, in practice it has stayed in place most of the time in the GMC workshop.
The ability to dimension even small components to length quickly is invaluable. However, the fence behind the workpiece requires you to hold the work firmly against the fence, whereas with the fence in front the workpiece will of course stay put.
Noise levels were OK and both sawing and spindle moulding produced accurate results. It would have been nice to have a more precise method of setting fence-to-blade distance on the saw though.
Extraction can be done using a Hammer splitter box with one small branch going to the crown guard. The level of extraction off the crown guard is not as high as one would like so wearing proper PPE (personal protection equipment) is still required.
f and c verdict
My colleagues and I have been fortunate in that we have been able to use this saw spindle combo over several months. Yes, it is pricey, but we have come to appreciate its accuracy, versatility and general all-round usefulness which tip the balance to make any drawbacks seem relatively minor.
