OSG Carbide Spotting & Chamfering Drill - Micro Grain - TiAlN - 100° - 12mm

The OSG Carbide Spotting & Chamfering Drill is a dedicated tool for starting holes cleanly and forming exact chamfers with a 100° angle. Sized for a 12 mm diameter, it delivers reliable performance across a variety of materials, making it ideal for machinists, fabricators, and hobbyists who need precise chamfers without a secondary operation.

Made from micro-grain carbide and finished with a TiAlN coating, this drill resists wear, stays sharp longer, and maintains consistent results across metals and other hard materials. The 100° chamfer angle ensures proper edge geometry in challenging applications, while the TiAlN coating boosts wear resistance for longer tool life.

• Precise 100° chamfering geometry: Delivers consistent, clean chamfers at 100° every time, reducing the need for post-process finishing and ensuring parts meet tight edge-spec requirements.
• TiAlN-coated micro-grain carbide: Provides superior wear resistance and extended tool life, maintaining sharpness through demanding materials and long production runs.
• Dual-purpose spotting & chamfering in one tool: Combines hole starting and edge chamfering in a single operation, saving setup time, reducing tool changes, and improving overall workflow.

This tool supports efficient production by delivering reliable hole starts and precise chamfers with repeatable results. Its robust construction and coating enable consistent performance across a range of materials, helping you cut downtime, reduce rework, and achieve high-quality finishes on every part.
