This tool is tailored for tasks where a compact, high-precision slot drill is essential. The extra-short length enhances rigidity to reduce tool deflection during deep cuts, while the 30° helix supports smooth chip evacuation and a stable cutting action. The powder metallurgical HSS-E composition offers improved wear resistance and durability, helping extend tool life in tough workpieces. With a Weldon shank for secure seating in standard holders, it provides repeatable performance across demanding production runs.
