Its feature set delivers accurate hole starts and long-term performance: a 135° split point for self-centering, premium HSCO material for drilling a variety of metals, and a heavy‑duty construction to handle demanding applications.

135° split point for self-centering: starts holes cleanly and reduces wandering, lowering the push force required for easier, more precise drilling.
Premium HSCO material: enables durable, versatile drilling across a wide range of metals, including steel, aluminum, and stainless steel.
Heavy‑duty design for demanding work: built to withstand tough materials and challenging applications, delivering reliable performance and long tool life.

Together, these features translate to faster, more accurate drilling with fewer reworks and smoother finishes. The A777 combines compatibility with DIN 338 tool holders, durable construction, and versatile material performance, giving professionals and hobbyists alike a dependable choice for everyday metalworking projects.
