Are PCD Blades Right for Your Shop?

Regardless of whether you’re a small to medium sized cabinet shop or a large production facility, if you haven’t considered PCD (polycrystalline diamond) saw blades perhaps now is the time!  Materials such as particle board, MDF, laminates and solid surface are all excellent candidates for diamond saw blades. When comparing Diamond v. Carbide, depending on the machine and the material application, diamond saw blades can outperform carbide by a ratio of 30-50 times!  

PCD Main Blade

Over the years, diamond saw blade production has improved tremendously and as an industry, we’ve seen steady prices reductions.  With the multitude of suppliers now offering PCD tooling it’s important for you, the buyer, to do the proper vetting of the individual supplier.  There are many factors to consider when looking at the price of a diamond blade, including the plate and diamond quality, the amount of diamond used, and the cost to service the tool.

Here is an example use case from one of our customers:

A cabinet manufacturer located in Florida and utilizing a Holzma Model 430 beam saw found they were changing their carbide main and scoring blades on a daily basis! At the beginning of 2016, they invested in a 450 mm PCD main and 180 mm PCD scoring saw. The diamond saw blades were put into production on January 4th and were removed from production for sharpening on April 7th, 69 production days! Needless to say, a second diamond set was ordered.

From replacing carbide saw blades on a daily basis to running 69 production days on one diamond set! Considering the cost of a diamond set can be 10 – 12 times the price of a carbide set it leaves little doubt that in this case, the initial cost factor is far outweighed by the extended tool life most certainly justifying the investment. In addition, this doesn’t take into consideration the cost of having to maintain the huge number of carbide sets needed for rotation purposes or the machine downtime savings created. When deciding whether to switch, be conservative in your cost analysis and base your justification on the diamond tool lasting 25x longer than carbide.  You won’t be disappointed!

Vari-Angle Insert Cutter Head

4058 effekt 4058.160.30

The 4058 Vari-Angle Insert Cutter Head is a versatile tool that’s invaluable for any custom woodworking facility, especially moulding and millwork shops. This tool is like no other insert cutter-head on the market and it’s used on a number of machines including shapers, tenoners and moulders. What makes this tool truly unique is its ability to joint at 90 degree producing a wide range of angles, hence the term, “Vari-Angle”.  Manufactured from lightweight aluminum, this tool offers ease of handling and angle adjustment, and is something no wood shop should be without! Great solution for a range of different edge bevels and angled cuts.  The Vari-Angle Cutter Head is produced with two tilting apparatus heads allowing the cutter head to be adjusted to produce varying angles (up or down) from 0 –  90 degree. This is achieved by the use of a simple wrench, turning an inner gearbox that allows the precise adjustment to the desired angle.

Once the angle is located, the wrench is then used to securely and accurately lock the tilting heads into place. The precise location of the angle is confirmed through a vernier scale located on the cutter head. In most cases, the simplicity and location of the adjustment gearbox allows the cutter head to be adjusted while still on the machine! The tool is available in diameters ranging from 110mm and 170mm and depending on the model, has a cutting capacity of 40, 50, 60 and 80 mm.   The adjustable vari-angle cutter uses standard reversible carbide insert knives making it an extremely economical tool to operate.   Please contact us for more information.
