The Dormer Pramet C367 18.0 mm slot drill combines rugged HSS‑E with an Alcrona Primax coating to deliver reliable shoulder and slot milling in metalworking projects. Designed for machinists and shops that need precise pockets and clean slots in steel and aluminum, this extra‑short tool provides rigidity and control in compact geometries.

• Diameter and length of cut: 18.0 mm diameter with 19.0 mm length of cut (DOC) for efficient material removal in tight slots
• Overall geometry: 79 mm overall length with 30.5 mm reach and neck relief to reduce rubbing and improve engagement in shallow pockets
• Shank: 16 mm Weldon shank for secure grip, reduced runout, and compatibility with standard endmill holders
• Flute count: 3 flutes for a balanced combination of rigidity, chip evacuation, and a smooth slot finish
• Material and coating: Powder metallurgical HSS‑E substrate with Alcrona Primax coating for increased wear resistance and longer tool life
• Helix and rake: 40° helix and 15° rake angle optimized for shoulder milling, slot milling and ramping across ferrous and non‑ferrous metals
• Standards: DIN 327 D specification ensures compatible shank and seating in common tooling systems
• Material compatibility: Suitable for free machining steel, stainless steel, and wrought aluminium

This tool is ideal for shops performing precise pocketing, slotting, and ramping operations where rigidity matters more than sheer diameter. The short series design minimizes deflection in narrow slots, while the 16 mm Weldon shank provides secure clamping and consistent depth control. The combination of Alcrona Primax coating and powder‑metallurgical HSS‑E delivers reliable performance in everyday manufacturing tasks, from prototype iterations to high‑volume production in metalworking environments.
