- Size: 1.60 mm diameter x 4.00 mm overall/working length
- Material: Premium HSS-E for toughness and versatility across common metals
- Coating: Titanium Aluminium Nitride (TiAlN) increases wear resistance and service life
- Angles: 118° pilot with a 60° centre drill cone for accurate centering and clean holes
- Double-ended: Two drilling ends deliver greater productivity and extended tool life per purchase
- Standard: DIN 333A compatibility for broad machine and holder compatibility

Designed for engineers and machinists who demand consistent center-hole quality, this centre drill minimizes runout, reduces secondary operations, and lowers tooling costs through its dual-ended design. The TiAlN coating helps sustain edge sharpness on harder materials, while the robust HSS-E core maintains strength under demanding feeds and depths. Compatible with both CNC and conventional machines, the A266 is a dependable choice for shopfloor centering tasks.
