The Robert Charles Rose Countersink DIN 335A x 90° with a 20.0 mm head diameter is a precision cutting tool designed for accurate countersinking and chamfering. Engineered to DIN 335A standards, it delivers burr-free finishes across steel, aluminium, and plastics, making it a reliable choice for workshops, engineering shops, and production environments where precision matters.
- DIN 335A Precision Standard: Conforms to DIN 335A specifications to ensure consistent countersink depth and chamfer quality across common materials.
- Multi-flute Cutting & Chip Evacuation: Several flutes deliver smooth, stable cuts with efficient chip removal for cleaner finishes and reduced heat buildup.
- Rigid 90° Rose Geometry (20 mm head): Sturdy design minimizes vibration and deflection, producing burr-free edges and longer tool life on steel, aluminium, and plastics.
This countersink helps you improve workflow by delivering repeatable, ready-to-use countersinks, minimizing deburring time and rework. The combination of DIN-grade precision, robust construction, and efficient chip evacuation translates to faster setup, more consistent finishes, and reliable performance across demanding applications in fabrication, assembly, and prototyping.
