Engraving cutter Pro A Ø12 mm, HSS‑EW9Co10 – Werner Wilke, hardened precision cutter, Ø12 mm, L 125 mm

The Engraving cutter Pro A Ø12 mm HSS‑EW9Co10 is a precision tool for engraving letters, contours and for copy milling, featuring a straight cutting edge and pre-ground halving for reliable centring

• HSS‑EW9Co10 with 10% cobalt
• Hardened to 65–69 HRC
• Diameter tolerance h8
• Precision-ground straight cutting edge

Long-lasting cutting performance from high-speed steel with cobalt

The use of HSS‑EW9Co10 (Werkstoff 1.3207) with a 10% cobalt content provides enhanced red-hardness and wear resistance compared with standard high-speed steels; this translates into longer tool life under sustained loads and higher cutting temperatures, which reduces the need for frequent replacements and supports stable batch production. The combination of a hardened substrate and a precision grind ensures a consistently sharp profile for fine detail work, keeping downtimes low and throughput predictable.

Precision tolerances for repeatable engraving results

A strict diameter tolerance h8 and a length tolerance of ±2 mm guarantee that tool dimensions remain within close limits, improving part-to-part consistency on CNC engraving machines. The halfing tolerance +0.1 mm and the pre-ground halving (D×1.5) support accurate positioning in fixtures and minimise runout, so patterns and lettering retain uniform depth and legibility across multiple components. These measurable tolerances are particularly relevant for production runs that demand traceable accuracy.

Designed for engraving letters, contours and copy milling

The straight cutting edge and a cutting length of 18 mm make this profile ideal for crisp lettering and fine contour work, while the overall length of 125 mm provides sufficient reach for most engraving and copying operations. The tool is suitable for use with standard toolholders and fixtures used in workshop and light industrial settings, enabling straightforward integration into existing CNC setups without complex adaptation.

Practical workshop benefits and application guidance

Hardened to 65–69 HRC and precision-ground, this cutter offers robustness when working on a range of materials commonly encountered in engraving tasks. The specification emphasises controlled performance rather than experimental coatings, so process parameters such as feed and spindle speed should be set with the material and cutter geometry in mind. For application-specific recommendations or to confirm compatibility with a particular workpiece material, technical consultation is available to match the tool’s profile and tolerances to the machining task.

FAQ

Which materials is this cutter suitable for?
The engraving cutter Pro A (Werner Wilke, SKU 4118430035NW) is specified for precision engraving and copy milling; material suitability depends on machining parameters and workpiece hardness given the tool’s 65–69 HRC substrate.

What does HSS‑EW9Co10 mean for tool behaviour?
HSS‑EW9Co10 indicates a high‑speed steel grade with elevated cobalt content (10%), providing improved red‑hardness and wear resistance compared with ordinary HSS, which benefits sustained engraving operations.

How precise are the dimensions of the cutter?
The tool is manufactured to diameter tolerance h8 with a length tolerance of ±2 mm and a halfing tolerance of +0.1 mm, supporting consistent positioning and repeatable engraving results.

Can this cutter be used for copy milling on CNC machines?
Yes; the Pro A profile with a straight cutting edge and cutting length 18 mm is intended for engraving and copy milling tasks and is compatible with common CNC engraving setups.

Is the halving pre-ground and what is Dx1.5?
The halfing is pre-ground to aid accurate centring; the notation D×1.5 refers to the preparation of the halving diameter relative to the cutter for correct seating in fixtures.
