Vortex Spot Drill - 90° Cobalt HSS-E Uncoated - 20mm

The Vortex Spot Drill is a purpose-built 20 mm spot drill designed for professionals who need fast, accurate center holes to guide larger drilling or milling operations. Built from HSS‑E cobalt and left uncoated, it delivers dependable performance under demanding metalworking conditions.

• Diameter: 20 mm
• Material: HSS‑E Cobalt alloy for added strength and heat resistance
• Coating: Uncoated surface maximizes contact with the workpiece and promotes consistent chip evacuation
• Point angle: 90° tip for a sharp, precise entry and clean center hole
• Chip control: Optimized geometry reduces built-up edge and improves hole accuracy
• Application: Creates a reliable center hole to guide subsequent drilling or machining operations

With its cobalt-enriched HSS-E construction, the drill maintains cutting efficiency at higher temperatures, helping extend tool life in tough metals. The uncoated finish ensures direct contact with the workpiece for stable guiding and efficient chip clearance, minimizing wander and delivering repeatable center holes. The 90° point yields a crisp starting entry, reducing drill walk and providing consistent hole placement for reliable downstream operations. This spot drill is well-suited for prep work in metal fabrication, automotive, and general machining workflows where precise center holes are essential for accuracy and repeatable results.
