The Robert Charles Rose Countersink DIN 335A is a purpose-built tool for creating accurate 90-degree chamfers and countersinks in metal, aluminium, and plastic components. It meets strict DIN 335A requirements so workshop users, engineers, and production teams can produce consistent, burr-free results without extra finishing steps.
- Multi-flute cutting action: Multiple cutting edges maintain smooth, stable contact with the workpiece while clearing chips quickly to prevent clogging and surface marks.
- DIN 335A precision build: Manufactured to recognised standards so every countersink matches the intended angle and depth, reducing the need for rework or trial cuts.
- Rigid shank construction: The solid body minimises flex and vibration, allowing steady feed rates even on tougher materials or in handheld and machine setups.
With clean chamfers produced in a single pass, this countersink shortens setup and finishing time while protecting surrounding surfaces from damage, giving reliable performance across daily workshop use and longer production runs.
