This drill bit combines precision engineering with a tough design, making it a dependable choice for deep-hole drilling in a range of materials.

Key features that set this drill apart:

• 118-degree conventional point – delivers a strong, self-centering start that’s easy to re-sharpen, helping you maintain accuracy and extend tool life even after repeated use.
• Steam oxide finish – reduces material sticking to the cutting edge, promoting smoother chips evacuation and cleaner holes with less built-up edge.
• Extra long length – purpose-built for drilling very deep holes or situations where extended reach is required, minimizing the need for multiple tools or workpiece repositioning.
• Premium HSS material – high-speed steel provides solid performance across a variety of workpieces, including steel, aluminum, and stainless steel, while preserving hardness and edge retention.
• Straight shank – versatile compatibility with a wide range of drill presses and handheld drilling machines, ensuring secure clamping and stable cutting action.
• Versatile, reliable performance – designed for demanding applications in fabrication, automotive, moldmaking, and general metalworking where long reach and dependable cutting are essential.

Ideal use cases include drilling deep pilot holes in steel assemblies, creating precise through-holes in aluminum components, or reaching recessed work areas where standard-length bits fall short. The A125 drill delivers consistent hole quality, clean chip formation, and predictable wear patterns, making it a practical upgrade for workshops that tackle frequent deep-hole tasks.
