Frequently Asked Questions

What is the OSG spiral point tap used for?

The OSG spiral point tap is used for threading blind or through holes in metal, particularly in production environments. Its spiral point design pushes chips forward, reducing clogging and enabling faster tapping cycles. It is suitable for general-purpose threading in materials like steel, aluminum, and cast iron.

What are the specifications of the OSG spiral point tap?

This OSG tap has a metric M4.5x0.75 thread size with a D4 / 6H tolerance class. It features 2 flutes, a plug chamfer, and is made from black oxide high speed steel. The manufacturer part number is 1982301. It is designed for general-purpose tapping in blind or through holes.

Where to buy OSG taps in worldwide?

You can source OSG taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times on this OSG spiral point tap or other threading tools.

How to select the right OSG tap for a threading application?

Select an OSG tap based on thread size, material, and hole type. For blind holes, use a spiral point tap to push chips forward. Match the tap's tolerance class (e.g., 6H) to the required thread fit. Consider coating and flute count for chip evacuation and tool life. Consult OSG's technical data for specific material recommendations.
