The Walter Titex A3389AML-2.6 is a new, solid carbide micro drill with a 2.6 mm cutting diameter, AlTiN (aluminum titanium nitride) coating, and through-coolant capability, as confirmed by the box label reading 'CARB ALTIN CLNT MICRO DR.' The A3389AML series features a 140° point angle, a cylindrical shank sized to the drill diameter (no step-shank reduction), and is designed for deep-hole micro-drilling in steels, cast irons, and stainless steels where thermal stability and chip evacuation are critical. The through-coolant channels deliver cutting fluid directly to the cutting edge, extending tool life and enabling higher feed rates in demanding CNC machining center applications. The black AlTiN coating provides oxidation resistance up to approximately 800°C, making this drill suitable for dry or minimum-quantity lubrication (MQL) strategies in addition to flood coolant. Walter's internal part number RS1975371 and EAN 70595962 confirm this is an authentic OEM production item packaged individually in the standard green Walter Titex protective holder.
