Description
The OSG Carbide Spotting & Chamfering Drill (12 mm) is a precision cutting tool designed for machinists, fabricators, engineers, and hobbyists who need accurate spotting and chamfering with a clean, consistent edge. Made from micro-grain carbide and left uncoated, it delivers dependable performance at a 100° chamfer angle for reliable results across a range of materials.
- Micro-grain carbide construction: provides exceptional durability and long tool life, so you can complete more chamfering and spotting tasks before needing a replacement.
- Precise 100° chamfer angle: enables accurate, repeatable chamfers with clean edge geometry, reducing finish work and improving part fit.
- Uncoated design with 12 mm diameter: offers broad material compatibility and predictable cutting action across different materials and setups, supporting quick, confident installations.
By choosing this drill, you gain reliable performance that supports faster, more consistent chamfering results. The tough carbide core resists wear in demanding applications, while the 100° geometry delivers crisp edges and repeatable outcomes. This combination helps streamline workflows, reduce downtime, and elevate overall machining quality.
