Engraver bit PFERD WRC 1225/6 Z3 PLUS, 6 mm shank, Ø 1.2 cm, length 65 mm

PFERD WRC 1225/6 Z3 PLUS is a single-piece solid carbide engraver bit with a 6 mm shank, 12 mm cutting diameter and a total length of 65 mm. Manufactured in Germany and produced to DIN geometry standards, the cutter combines a cylindrical body with a radius (ball) end for versatile milling, deburring and engraving operations. The tool is intended for work on steel, stainless steel, aluminium, bronze and other non-ferrous metals and is suitable for precision metal fabrication where accurate profile shaping and surface finishing are required.

Advantages

The combination of cylindrical and ball-shaped geometries provides controlled chip formation and consistent surface contact at the tool tip, while the single-piece solid carbide construction ensures stiffness and dimensional stability during high-speed rotation. A long steel shank gives reliable mounting in collets and allows deeper reach into workpieces. Cut geometry conforms to DIN standards to support predictable cutting behaviour and repeatable results across milling, engraving and deburring tasks.

Suitable for

• Milling and profiling small contours in steel and stainless steel
• Deburring edges and holes on metal components
• Engraving text, numbers and shallow reliefs in non-ferrous metals
• Precision toolroom and fabrication work requiring a combination of cylindrical and radius end shapes

Key specifications

• Shank diameter: 6 mm (long steel shank)
• Cutting diameter: 12 mm
• Total length: 65 mm (solid tungsten carbide body)
• End shape: cylindrical body with radius (ball) end
• Cut type: three-flute cutting geometry conforming to DIN
• Material compatibility: steel, stainless steel, aluminium, bronze and other non-ferrous metals

How to use

Secure the 6 mm shank in an appropriate collet or chuck with sufficient clamping length to minimize runout. Select spindle speed and feed based on workpiece material and machine capabilities; begin with moderate speed and conservative feed to verify cutting behaviour. Use steady, light axial engagement for engraving or profiling and increase depth of cut incrementally when milling. Ensure adequate chip evacuation and cooling according to material: for stainless steel use lower cutting speeds and intermittent coolant if available, while aluminium typically allows higher speeds with air or minimal lubricant.

Usage recommendations

Inspect the tool for wear or damage before each use and replace when cutting performance deteriorates. Maintain proper collet condition to reduce runout. For highest accuracy, perform a test cut on a sample piece and adjust parameters. Follow machine and workplace safety practices, including eye protection and guarding against flying chips.
