DART PCD Blades – Tough & Long Lasting!

17-08-2017

Why PCD?

PCD is a polycrystalline diamond, manufactured by sintering together carefully selected diamond particles at a very high temperature and pressure in the presence of a solvent/catalyst metal. The result is an extremely tough inter grown mass of randomly orientated diamond crystals bonded to a tungsten carbide substrate. PCD, therefore can be regarded as a composite material which combines the hardness, abrasion resistance and high thermal conductivity of diamond with the toughness of tungsten carbide.

Polycrystalline is ultimately an extremely hard material – harder than tungsten and carbide, so will outperform a TCT blade by up to 50 times life wise.

Another advantage of the DART PCD blade is that it creates very little dust unlike the abrasive discs often used, as it produces a shaving rather than a powdery dust, even in cement board.

When is PCD used?

Correctly applied, PCD tooling replaces existing tool materials such as HSS or tungsten carbide. With the rise in use of wood substitutes (such as wood composites and plastic woods) for future house building in the construction industry – the traditional TCT Blade struggles to cut many of these new materials – leaving an untidy, unattractive cut and the need to replace the blade frequently. This is where the PCD Blade can be seen as a must in any building or timber merchants, as it offers the user an effortless, clean cut in a huge variety of ultra-hard materials. Just to name a few - it will cut through cement fibre board products, such as Marley Eternit, HardiePlank, ‘No More Ply’,  MDF and Corian, as well as laminated and melamine surfaces, GRP, softwoods and hardwoods, plywood and chipboard.

How do they compare cost-wise?

The cost of a PCD Blade can be up to 10 times more expensive than a TCT Blade – but there are extra considerations to take into account. When cutting through certain materials, the user often needs to change a carbide blade daily, while the polycrystalline can last up to 50 times longer – so there is little doubt that the initial cost factor is far outweighed by the extended tool life. In addition, this doesn’t take into consideration the cost of having machine downtime and the time-savings associated with using a PCD blade.

DART Tool Group is a trusted and reliable supplier of PCD blades. With a range of sizes starting at 160 mm and going up to 300mm, with 4 to 8 teeth and an extra-large gullet design, which minimises dust and improves removal of material – you can be guaranteed a smoother, cleaner and more accurate cutting– if you haven’t considered PCD yet, then now is the time!
