OEM Carbide Tooling

Doutt Tool specialize in precision grinding miniature carbide punches that many other tool shops would choose to Wire EDM.
The reason some tool shops choose to wire is simple to understand - wiring carbide is relatively easy, fast and cheap and any internal radii can be eliminated by making tiny undercuts written into the wedm cutting program.
But, here's the catch, the surface finish on any wired carbide part has surface micro fractures and while that's no problem for a full sized punch, it can be sudden death to the tiny, highly stressed areas of a small punch working at say 800 strokes a minute.
Breakage's may be unpredictable but they are not unexpected.

Doutt Tool considers this risk of fracturing to be unacceptable.
We are experts in surface grinding carbide micro punches and we know that grinding will give a surface finish entirely free from micro fracture defects.
 
Our toolmakers pick from a selection of 500 plus dressed diamond wheels and they have the capability to grind virtually any carbide tooling - take a look at the Micro Punch selection here.

Cost Saving

Doutt Tool has built a custom fixture that will dress a diamond wheel to produce internal radii from .002" to .800" and outside radii up to 1.000" and our ability to create any radius means that we can make parts for you in carbide at less cost than the same part in any tool steel.
Our inventory of 500 diamond wheels are pre-dressed with radii from .002" to .034" in .001" steps and various other radii to .800".

With this kind of support our toolmakers can concentrate on what they do best - producing high quality carbide tooling fast - because they don't have the tedious process of making individual wheels for every part they make.
The time savings created for our toolmakers are reflected in an extremely lean pricing structure with the benefits passed on to you.
