Diamond and Insert Trimmers for Edgebanders


Shown here is a diamond tipped premill edgeband cutter (in the back), a carbide insert radius trim cutter on the right, and a selection of insert knives for HolzHer, Biesse and other edgebanders.

GUHDO offers a wide range of tooling for most edgebanders, to include straight and radius trimmers and their replacement inserts, snip saws, and diamond (pcd) premill cutters.  Our PCD tools are manufactured per specifications of the original OEM for all edgebander makes and models including Adwood, Biesse (Polymac/Stream), Brandt, Bussellato, Casadei, Cehisa, Fravol, HolzHer, Homag, Olympic, SCMI, Stefani, Delmac, IDM, Griggio and IMA. When it comes to the PCD (polycrystalline diamond) tooling on the trimming units, GUHDO offers a complete replacement tool program. Depending on the application the tools available are straight, bevel, radius, multi-radius and combination radius/bevel cutter heads.

Getting Deep on Diamond Tooling

Diamond is known as a material with impressive characteristics. Even the name, Diamond, which stems from the ancient Greek word  “αδάμας” – “adámas,” translates to unbreakable. In particular diamond is the hardest mineral known and also has the highest thermal conductivity. These two traits, in addition to its abrasion-resistance,  make Diamond quite a popular material in the industrial tooling area. To illustrate the level to which diamond tools surpass carbide tools in regard to hardness, one only has to compare each materials value on the Knoop hardness scale. While synthetic diamond generally rates between 5000 to 7000, the average hardness for a carbide tool only has a value of about 1700 to 2400.

Polycrystalline Diamond tools are an established, well accepted solution for high volume production and they are now cost effective as well. They have long proven to be an investment in quality AND productivity as they can provide substantial savings in tooling costs.

Based on case histories, polycrystalline diamond tools can outlast a carbide tool by a ratio of roughly 300:1. However, this takes into account a wide range of materials machined.   So, while one machinist may achieve a ratio of 50-fold life span for a diamond tool cutting very abrasive material, another may outrun his previously used carbide tool by 800 times on a solid wood application.

Today, diamond tools have earned their position in most every woodworking, composite, plastic and solid surface cutting application.  From routing and edge-banding, profiling, sawing, jointing and grooving to slotting and hogging; diamond tools are used in almost all cutting tool applications.

Today’s modern manufacturing facilities  are running expensive CNC machining centers with constant demand for higher output and lower unit costs being paramount.  Most CNC machinists have recognized the value of diamond cutting tools. Elimination of downtime alone can result in a significant reduction in tooling costs, not even taking reduced sharpening costs, stocking needs and lost production into consideration.

Although diamond tools may not be the solution to every tooling issue, they should not be excluded from consideration without a thorough analysis of the potential advantages. With today’s ever-increasing demand for higher efficiency and lower costs, the toughest material may just solve the toughest tooling problems!

Diamond vs. Carbide Tooling Cost Comparison


Diamond Router Bits

It is well-known that Polycrystalline Diamond (PCD) tooling delivers high performances in cutting applications while also significantly while reducing a company’s overall tooling costs.  Under the right conditions and with the proper maintenance, great cost savings can be achieved. The first tool life can yield savings of up to 30 -50% in comparison to carbide tools or inserts. And subsequent sharpenings will further increase the savings when compared to a carbide tool or insert.

The calculation quite accurately illustrates, that although at first look Diamond tools seem to be a costly investment, it is an investment that pays off rather quickly and costs only a fifth of what equivalent Carbide tools would cost.

It may not be necessary to buy Diamond Tools for everyone and every company, but especially those who need their tools to last as long as possible and would like to get as much use out of them as possible, will find that investing in diamond tools is more than cost-effective.  The best applications for diamond tools are those machining  abrasive materials and doing high volume of the same cut.
