The Dormer Pramet C353 22.0mm HSS-E-Powder Metall Alcrona Primax Flatted Shank 3 Flute Short Series Slot Drill DIN 327 D is a compact, high-precision slot drill designed for shoulder milling, slot milling, and ramping in a range of metals. Built for use in constrained spaces, it combines a robust HSS-E core with a durable Alcrona Primax coating to extend tool life and maintain clean, accurate cuts.

• Diameter / Length of Cut: 22 mm diameter with 22 mm length of cut for precise, controlled material removal.
• Overall Length / Reach: 88 mm overall length with a 37.5 mm reach and neck relief to improve accessibility in tight pockets and deep slots.
• Shank Type: 20 mm Weldon shank for secure clamping and compatibility with standard toolholders.
• Material & Coating: Powder-metallurgical HSS-E with Alcrona Primax coating for enhanced wear resistance and extended life in tough steels and alloys.
• Geometry: 30° helix and 12° rake angle optimized for shoulder milling, slot milling, and ramping in steel, cast steel, cast iron, copper/copper alloys, and titanium alloys.
• Flutes: 3 flutes delivering strong chip evacuation and stable cutting in a short-series design.
• Standards: DIN 327 D conformity ensures compatibility with DIN-standard tooling and holders.

This tool is ideal for workshops and production environments needing reliable performance in constrained spaces. The extra-short design provides rigidity for clean shoulders and accurate slots, while the 3-flute setup balances material removal with finish quality. The Alcrona Primax coating reduces wear, helping extend tool life across a variety of metals, including titanium and copper alloys. Use it for precise shoulder milling, slot milling, and ramping in both ferrous and non-ferrous materials, and expect stable cuts, reproducible results, and fewer tool changes in mid- to high-volume workpieces.
