Description
The OSG Carbide Spotting & Chamfering Drill is a purpose-built tool designed for precise spotting and chamfering across a range of materials. With a 16 mm diameter and a 142° chamfer angle, this micro-grain carbide drill delivers clean, consistent edges even on challenging materials, making edge preparation reliable in professional machining, fabrication, and workshop environments.
- Durable micro-grain carbide construction: Delivers excellent wear resistance and edge retention for long tool life, maintaining sharpness through repeated chamfering and spotting tasks on hard or abrasive materials.
- Precise 142° chamfer angle for consistent edges: Ensures uniform chamfers and reliable edge geometry in every pass, reducing the need for secondary finishing and helping parts meet tight tolerances.
- Uncoated carbide for versatile performance: Provides predictable cutting action across a variety of materials and minimizes coating wear or delamination in demanding machining environments.
This combination helps streamline workflows by enabling spotting and chamfering in a single operation, cutting setup time and finishing steps. The tool’s durability and precise geometry improve edge quality, reduce rework, and extend productive machine uptime, making it a dependable choice for shops, job sites, and assembly lines that demand consistent, professional results.
