This slot drill is tailored for precise, repeatable cuts in challenging materials. The 2‑flute configuration supports efficient material removal and effective chip control in restricted slots. The 30° helix and 12° rake are optimized to reduce cutting forces and improve surface finish when creating slots, shoulders, or ramps. With its durable HSS‑E powder metallurgy construction and a bright finish, the C123 delivers reliable wear resistance and long tool life in everyday milling tasks. Ideal for tooling setups that require a single, high‑quality cutter capable of handling multiple milling operations without frequent tool changes.
