Werner Wilke Pro A engraving cutter, 8 mm – HSS‑EW9Co10, 90 mm overall

Werner Wilke Pro A engraving cutter for detailed engraving, contour work and copy milling, manufactured from HSS‑EW9Co10 and precision ground for consistent results

• Hardened HSS with 10% cobalt
• Diameter 8 mm, tolerance h8
• For engraving and copy milling
• Precision ground, hardened and tempered

High‑performance cutting for precise engraving

The HSS‑EW9Co10 construction with an elevated cobalt content provides increased red‑hardness and wear resistance compared with standard high‑speed steels, supporting sustained cutting performance when profiling fine letters and contours. The tool is hardened, tempered and precision ground, which ensures a consistent cutting geometry and repeatable results in series work. Tight dimensional control—diameter tolerance h8 and length tolerance ±2 mm—reduces setup variance and shortens machining time, while the 12 mm cutting length allows controlled engagement for delicate features.

Consistent quality that improves workflow

This solid‑steel engraving tool is engineered to keep processing stable: the straight cutting edge and pre‑ground halfing aid in reliable centre entry and clean contour transitions. As a consequence, tool changes and rework are minimised, delivering a measurable improvement in cycle reliability and a lower rate of rejects. The robustness of the material and the 65–69 HRC hardness rating of the cutting portion support frequent use in toolrooms and small production runs where repeatability and surface finish matter.

Practical compatibility and application clarity

Suitable for use on a variety of non‑ferrous and ferrous substrates in precision applications, this cutter excels for fine scripts, logos and template copying. The 8 mm dimension makes it compatible with common tool holders and collets found in engraving machines and small CNC routers, enabling straightforward integration into existing setups. The tool’s specification explicitly states its application for engraving of lettering and contours as well as for copy milling, so selection is clear for workshop planners and machinists seeking a specialist finishing instrument.

Built for professional environments and predictable supply

The component’s traceable material designation (1.3207) and the explicit tolerances allow planners to document process capability and inspection criteria with ease. The tool is delivered as a single‑item packaging unit, easing stock control for procurement teams. In addition, the combination of precise grinding and a defined halfing tolerance +0.1 supports reliable fixturing and minimal runout when mounted correctly, which translates into improved surface quality and less polishing or rework downstream.
