Description

The OSG Slow Spiral Carbide Drill is a solid, uncoated cutting tool designed for precision and versatility across metals, plastics, and composites. Its slow spiral design promotes controlled chip evacuation and helps minimize workpiece distortion during hole creation. With a 4.2 mm diameter, this drill delivers reliable, consistent results in a wide range of applications—from fabrication and maintenance to hobbyist projects.

  • Controlled chip evacuation: The slow spiral flute guides chips away smoothly, reducing heat buildup and the risk of chip binding so you get cleaner starts and straighter holes.
  • Durable carbide construction: Solid carbide provides rigidity and wear resistance, delivering long tool life and repeatable hole size even in tougher materials.
  • Uncoated versatility: The uncoated surface minimizes coating-related compatibility issues, making it suitable for metals, plastics, and composites without compromising performance.

Designed to fit into everyday production, this drill helps you finish tasks faster with fewer adjustments. The combination of slow spiral geometry and carbide rigidity delivers clean, round holes with tight tolerances, even in challenging materials. Its uncoated surface keeps material compatibility broad and maintenance simple, giving you a reliable, low-maintenance tool you can trust across jobs.
