OSG Carbide Spotting & Chamfering Drill - Micro Grain - Uncoated - 60° - 4mm

The OSG Carbide Spotting & Chamfering Drill is a precision tool designed for professionals who need accurate hole spotting and chamfering in a single pass. Made from micro-grain carbide and finished uncoated, this 4 mm diameter drill is engineered with a 60° chamfer angle to deliver clean, consistent chamfers across a variety of materials.

Ideal for machinists, engineers, and technicians who value reliable results and long tool life, this drill pairs durable construction with predictable performance. Its micro-grain carbide composition provides enhanced edge retention and wear resistance, helping you maintain quality through busy production schedules.

• Micro-grain carbide construction: Built for extended tool life and durable cutting edges, delivering consistent chamfer quality over many cycles.
• Precise 60° chamfer geometry: Produces clean, accurate chamfers on a wide range of materials, reducing the need for post-processing.
• Uncoated finish with 4 mm diameter: Offers versatile compatibility with common materials, while the compact 4 mm size gives you precise control for small-diameter work.

With this tool, you can streamline hole preparation by combining spotting and chamfering in one operation, saving time and minimizing setup steps. The durable carbide resists wear under demanding use, extending tool life and reducing replacement costs. The precise geometry ensures repeatable chamfer results, helping you meet tight tolerances and achieve a professional finish across projects, from assembly to finishing tasks.
