The Primax powder-metallurgical HSS-E composition delivers improved edge strength and wear resistance, helping you achieve cleaner slots and longer tool life in demanding materials. The 3-flute geometry supports efficient chip evacuation and stable cutting in slots up to 26 mm deep, while the 37.5 mm reach with neck relief enables deeper pockets and pockets with limited access. This drill is well-suited for shops that require a single, reliable 14 mm solution for a variety of materials and milling operations, from routine slotting to precision ramping in challenging alloys.
