Vortex Spot Drill - HSS-E Cobalt 120° Uncoated - 3mm

The Vortex Spot Drill — 3 mm, using HSS‑E cobalt with a 120° point — is a precision tool built for machinists and metalworkers who need fast, accurate centre holes to guide subsequent drilling or machining operations. Its uncoated finish and cobalt-enhanced alloy deliver reliable performance under demanding conditions.

• Diameter: 3 mm
• Material: HSS‑E cobalt alloy for added strength and heat resistance
• Point angle: 120° for precise, centered spot drilling
• Coating: Uncoated surface for maximum workpiece contact and efficient chip evacuation
• Function: Creates a clean centre hole to guide follow‑up drilling or milling
• Durability: Maintains consistent performance in tough machining conditions

Using this spot drill helps you start holes exactly where intended, reducing wandering and the need for rework. The 120° point delivers a sharp, well-centered first cut, while the cobalt alloy resists heat during higher‑speed operations. The uncoated surface promotes excellent contact with the workpiece and steady chip flow, helping to keep temps down and the cut clean. Whether you’re setting up a new workpiece or preparing multiple parts, the Vortex Spot Drill supports reliable starts, smoother setups, and improved overall machining efficiency.
