Engineering Considerations for Solid Carbide and PCD Saw Blades in PCB Manufacturing As PCB materials continue evolving toward higher glass content, ceramic fillers, copper density, and advanced composite structures, tooling performance has become a critical variable in process stability, edge quality, and production economics. Conventional HSS and lower-grade carbide tooling often fail to maintain acceptable […]
Poor collet maintenance is one of the most common causes of short tool life and tool breakage. A router bit can only perform well if the collet securing it is gripping the tool shank evenly and full length. A small amount of time spent regularly inspecting and cleaning the collet and tool holder will increase […]
Not All Tool Holders Are Created Equal — See the Difference As the photo below illustrates, tool holder quality matters more than you might think. On the left, you’ll see a GDP heat-shrink tool holder, engineered in Germany to meet the highest ISO standards. Vacuum-hardened to 54 HRC, it offers superior corrosion resistance, enhanced tensile […]
If you are ever tasked with the challenge of identifying an HSK tool holder interface, the following will guide you through the differences and dimensions of the machine spindle interface (upper portion) of the HSK holder. These high-precision clamping tools are available in several configurations, including heat shrink construction, collet chucks, Weldon shank adapters, and […]
Finding replacement Edgebander tooling can be challenging with lead times often extensive and the cost eye-popping. Our extensive edgebanding tool selection includes a wide range of replacement inserts for straight and radius trim cutters, snip saws, scrape knives, PCD trim cutters and PCD premill cutters. In addition to our standard catalog items, we also offer […]
Since introducing our “Customize it” program over a decade ago, we have manufactured and delivered countless CNC custom profile tools in record speed and at prices that are impressively competitive! Made in Germany, this extensive CNC profile tooling program includes a wide range of in-stock tool body blanks which are manufactured in larger series to […]
PCD (polycrystalline diamond) premill cutters are often the “forgotten” tool on an edgebander. They may run for a year or more without needing to be sharpened and so noone thinks much about them until they get dull.
100 Years Ago Today…. Celebrating 100 years! Today, we fondly remember Herbert Doerken, on, what would have been his 100th birthday! (Jan. 4th). In 1986, Herbert was GUHDO USA’s founding majority partner. From post-World War II onwards, he was the driving force behind GUHDO Werk’s comeback to become one of Germany’s leading manufacturers of wood […]
Diamond Premill Cutter Diamond Premill Cutters for edgebanders such as Biesse, SCM, Brandt, Holzher and others, come in a variety of sizes and designs. Cutter specifications can be 2, 3 or even 4 wing, with PCD diamond brazed tips or diamond insert knives (which are not designed to be resharpened) and with different PCD tip […]
Carbide Insert V-Fold Mitre Bit for CNC Machining Our mitre-fold Insert V-Groove Router Bit boasts a special tip grind for perfect fold and a crisp corner clean out. Available in 91° standard version (#4320.050.34) which is used on wood and composite materials up to 25mm thick, which allows for expansion and glue space, there is […]
Torque Wrench Insures Proper Tool Clamping Proper tool clamping is an essential component of the tool assembly and performance. Over-tightening the collet nut can lead to collet distortion, tool runout and breakage, while not tightening enough can lead to tool slippage or worse. The best solution to avoid either scenario is to use a torque […]
