Engraving graver Pro A, 6 mm (HSS-EW9Co10) – straight cutting edge, hardened and precision ground, Werner Wilke

An engraving graver Pro A, 6 mm designed for precision lettering, contour work and copy milling in demanding metalworking and toolroom applications.

• HSS with 10% cobalt for improved toughness
• Hardness 65–69 HRC for excellent wear resistance
• Precision ground Profile A with straight cutting edge
• Diameter tolerance h8 and length tolerance +/- 2 mm

Precise results through a hardened, cobalt-alloy construction

The tool is made from HSS-EW9Co10 (material number 1.3207) with a 10% cobalt content, a composition that raises red hardness and edge stability under thermal stress. Combined with a hardness of 65–69 HRC, the graver delivers consistent cutting geometry over longer runs, reducing the need for frequent tool changes and ensuring steady results when producing fine lettering or detailed contours. This composition is particularly suited to applications where heat and abrasion challenge standard high-speed steels.

Reproducible contours and process efficiency in production

Thanks to the precision-ground Profile A and a straight cutting edge with pre-ground centring (Dx1.5), the graver enables accurate contour following and reliable copy milling performance. The 6 mm diameter and 9 mm cutting length provide a compact geometry that balances stiffness and accessibility for narrow contours. Tight tolerances—diameter h8 and length +/- 2 mm—support predictable fixture set-up and reproducible part quality, which in turn improves throughput and reduces scrap in series production.

Practical handling, sharpening and workshop integration

The component is delivered hardened, tempered and precision ground, making it ready for immediate use in standard toolholders suitable for engraving cutters. The tool’s surface and geometry allow controlled regrinding where necessary; however, the elevated hardness requires appropriate grinding equipment and cooling strategies to preserve the cutting edge. For everyday workshop workflows, the graver’s compact overall length of 80 mm and single-piece design simplify clamping and inspection, while the halfing tolerance +0.1 and pre-ground halfing help achieve consistent centring for replicable results.

FAQ

What is the primary application of this tool?
The Werner Wilke engraving graver Pro A (SKU 4118430015NW) is intended for engraving letters and contours and for copy milling where fine, reproducible details are required.

Which material and alloy are used for the tool?
The tool is manufactured from HSS-EW9Co10 (material number 1.3207) and contains 10% cobalt, providing improved red hardness and edge retention.

What tolerances can be expected from the graver?
Key tolerances are diameter h8, length +/- 2 mm and halfing tolerance +0.1, supporting predictable set-up and repeatable results.

Is regrinding feasible given the hardness?
Regrinding is technically possible; the item is hardened and precision ground to 65–69 HRC, so sharpening requires suitable grinding equipment and careful heat control to maintain edge geometry.

Can the graver be used for copy milling in series production?
Yes. The precision-ground profile and stable alloy composition are designed to support consistent reproduction in copy milling applications.
