Why diamond-tipped tools have an edge?

With many cutting tool options for industrial woodworking applications, why are diamond-tipped solutions said to be the right choice? Here are a few diamond cutting tool tips to help achieve better performance, higher quality output, cost savings and less maintenance in industrial woodworking applications.

Diamond-tipped solutions are provided in the form of moulder heads, shaper heads, tenon heads, hogging heads, CNC router bits, panel saws, scoring saws, gang saws, trim saws, grooving saws, and cutters for specialised machines.

Diamond tools are designed to match a customer’s specific application.  Look for the technical sales team that goes the extra mile to ask you for spindle RPM, feed rates, wood species, laminate types, cutting directions and grain directions.

The salesmen need this information to send to engineering and technical staff for evaluation, to be compared in a large database of cutting data.

Each tool manufacturer would want to match your specific needs from experience and create a custom cutting tool for your application.

Wood product manufacturers that are not taking advantage of the benefits of diamond-tip tooling over traditional carbide tip and insert tooling might be missing an opportunity. While not suitable for every cutting application, diamond can be used in many applications, including those involving solid wood, wood-based materials, plastics, or composites.

Advancements in diamond grades and sharpening technology also have resulted in higher impact resistance compared to carbide tooling, typically 20 to 75 times longer life, depending on the application!

There also is a higher tool life per cost ratio in favour of diamond-tipped tooling.

Another important feature to look for in diamond-tipped tools for profiling is the design; one that maximizes the number of sharpening’s while maintaining the exact profile shape every time.

One option is for adjustable stacked tool bodies combined with intricately machined tool bodies. This allows for large sharpening removals before replacing tips.

Another option is for profile tools in a single piece tool body.  However, while a one-piece tool body design will have a lower new tool price upfront, it can cost more across the total life of the tool, as service costs can accumulate more rapidly over time due to frequent replacement of the diamond tips.

There also is potential for compromising the tool life by repeatedly re-heating the brazed diamond tips in order to maintain the profile shape.
