With powder-metallurgical HSS-E, this drill combines hardness and toughness to resist wear and maintain sharpness through multiple passes. The extra-short body and 2-flute design help minimize chatter and produce clean slots, while the 30° helix promotes efficient chip evacuation and smooth entry. The 12° rake angle supports precise shoulder milling and controlled ramping, and the flatted Weldon shank provides secure, repeatable mounting in standard tool holders. Neck relief reduces rubbing in deeper slots, extending tool life and maintaining accuracy across longer cuts.
