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

Designed for machinists, engineers, operators, and serious hobbyists, the OSG Carbide Spotting & Chamfering Drill delivers precise center marks and crisp 60° chamfers in a single operation. With a 4 mm diameter, it’s ideal for preparing holes and finishing edges across a range of materials, helping you move from rough setups to finished parts more quickly.

• TiAlN-coated micro-grain carbide for extended life: The advanced coating reduces wear and dissipates heat, letting you cut harder materials longer and slice through demanding jobs with fewer tool changes.
• Precise 60° chamfer and center spot in one pass: Achieve accurate chamfers and locating marks without a secondary operation, improving hole alignment and edge quality across assemblies.
• Stable 4 mm diameter with clean-edge geometry: Robust internal design maintains sharpness and delivers consistent, burr-free edges on a variety of materials, enhancing finish and fit.

This single-tool solution helps streamline workflows by combining spotting, center marking, and chamfering into one dependable operation. Expect repeatable results, reduced setup time, and smoother assembly processes, whether you’re refining metal components, plastics, or composites. Rely on its strong construction and wear-resistant coating to maintain performance through multiple jobs, delivering reliable chamfers and precise hole preparation when it matters most.
