Description

Meet the Dormer Pramet C123 1/2" HSS-E-Powder Metallurgical Slot Drill — a precision two-flute tool designed for slot milling, shoulder milling, and ramping in steel and copper alloys. Its robust build and DIN 844 K specification make it a reliable choice for demanding shop environments.

  • Diameter: 1/2" (12.7 mm) cutting diameter for versatile slot and shoulder operations
  • Flutes: 2 flutes tuned for clean chip formation and stable cutting
  • Cutting length: 26 mm length of cut to reach through slots and pockets
  • Overall length: 83 mm for extended reach in deep cavities
  • Reach with neck relief: 37.5 mm to clear surrounding material during ramping
  • Shank type: 12 mm Weldon shank for secure clamping and repeatable seating
  • Material: HSS‑E powder metallurgy with bright finish for enhanced toughness and wear resistance
  • Geometry: 30° helix and 12° rake angle optimized for shoulder milling, slot milling, and ramping
  • Standard: DIN 844 K compatibility ensures reliable exchange with standard holders and collets

The C123 slot drill is built to deliver consistent slot dimensions and smooth cutting in steel, cast steel, and copper or copper alloys. The 2-flute design supports efficient chip evacuation and steady cutting action, while the powder-metallurgical HSS-E composition provides improved edge retention and toughness under typical milling loads. With a bright finish that helps monitor wear and a precise DIN 844 K fit, this drill offers dependable performance in everyday milling tasks and on reproducing accurate pocket and groove geometries.
