This tool is optimized for clean, accurate slots and pockets with controlled cutting action. The 30° helix promotes smooth chip flow and steady cutting forces, while the 12° rake angle helps maintain edge strength during shoulder and ramping operations. The powder metallurgical HSS‑E construction enhances wear resistance and edge retention, extending tool life under demanding metalworking conditions. The bright finish aids visibility and inspection of the cut, and the Weldon shank provides a secure, repeatable fit in standard collets and holders. Ideal for general engineering, automotive fabrication, and maintenance shops that demand dependable performance in ferrous and copper alloys.
