Wild Horses – Mustang by Name & Spirit

Perhaps a bit of creative license, but the Flai Mustang is a very interesting blade to have mounted in the table.  More formally called a multi-material blade, I prefer to think of it as a Universal Blade.  Or a Jack-of-all-trades.

The Multi-Material Mustang

It can be mounted in your tablesaw, and cut whatever you decide (or accidentally include) for it to cut, and in particular when dealing with reclaimed timber it is easy to miss the occasional nail, and this blade doesn’t think twice about it.

There is a compromise in that – the teeth are designed to cut wood and steel (mild), but that will mean it is not going to achieve a perfect finish when compared to a dedicated blade.  In saying that, it will be interesting to see just how large, or small that compromise is when I put the blade through the battle-of-the-blades tests.  Given its other design and construction features, it could still out-perform many of the dedicated blades, but I’ll reserve my judgement to the tests.

Mustang Teeth

There is another compromise – it has a pretty small gullet, so in ripping, particularly material prone to generating long fibres, the blade is going to struggle if the feed rate is too high.  But once again, if it is a choice between running a Mustang through timber prone to have hidden nails and running a dedicated rip blade and finishing with shattered teeth, well it is a no-brainer.

It has a surface treatment they have coined the “MetalGear Coating”, which is claimed to double the cutting capacity of the blade, and allow faster feed rates.  To achieve this coating, Flai uses PVD (Physical Vapour Deposition), where the coating (in this case a nitride coating) increases the surface hardness around 5 times.  The actual “gear” pattern that they achieve at the edge of the coating is just marketing.  But it looks good 🙂

The carbide tips are brazed on using a silver-copper-silver alloy which provides a lot more shock absorption capability than a standard silver brazed joint.  This is particularly important for a blade designed to cut both woods and metals – absorbing the impacts that would otherwise result in microcrack formation (and when a microcrack grows, it finally results in the loss of a blade’s tooth).

So that is a bit of a look at the Mustang, a TCT circular sawblade with neutral hook angle and triple chip teeth, a universal blade capable of cutting wood, wood derivatives, nail embedded wood, plexiglas, plastics, non-ferrous metals and mild steel.

I particularly like that nail embedded wood bit – being freed of the thought in the back of your mind that there might be missed nails etc in the bit of reclaimed timber you are about to cut is quite a liberating concept. In the past, seeing the remains of a nail that has been sliced by a quality blade is not unlike finding half a worm in an apple you’ve just bitten.  With this blade it becomes a “eh, whatever, extra protein” moment!
