Precision centre drilling for machinists who demand reliable starting holes with minimal setup. The Dormer Pramet A242 is a long-series, double-ended centre drill engineered for accurate centre holes in shafts and similar components.

  • Dimensions: 1.00 mm diameter x 4.00 mm overall length.
  • Centre geometry: 118° pilot with a 60° centre cone for precise alignment and clean hole starting.
  • Finish: Bright finish helps prevent workpiece material from sticking to the cutting edge and enhances chip flow.
  • End design: Double-ended construction provides two usable drilling ends for extended tool life.
  • Material: Premium HSS-E suitable for drilling steel, aluminium, and stainless steel.
  • Long-series reach: Extended length enables use in applications where increased reach is required.

The combination of a dedicated 118° pilot and 60° cone delivers reliable centering and concentric holes, improving holding accuracy during subsequent operations. Made from high-performance HSS-E, this centre drill handles a range of materials without frequent edge recutting, while the two ends and longer reach maximize productivity in setups with limited access or deeper center holes.
