Frequently Asked Questions

What is the OSG extension tap 1"-8 UNC used for?

The OSG extension tap 1"-8 UNC is used for threading blind or through holes in multiple materials, including steel, stainless steel, and cast iron. Its extended length reaches deep or recessed areas, while the spiral-point design pushes chips forward for efficient chip evacuation. The V-coated powdered metal construction provides wear resistance for production threading.

What are the specifications of the OSG extension tap MPN 1653505708?

The OSG extension tap MPN 1653505708 has a 1"-8 UNC thread size, H6 tolerance, 3 flutes, and a plug chamfer. It is made of V-coated powdered metal for durability. The spiral-point design is suitable for through-hole threading. These specs ensure precise thread formation in demanding industrial applications.

Where to buy OSG extension taps worldwide?

You can source OSG extension 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 time. 3G Electric supplies genuine OSG cutting tools for manufacturing and maintenance operations globally.

How to select the correct OSG extension tap for threading?

To select the correct OSG extension tap, match the thread size (1"-8 UNC), chamfer type (plug for blind holes), and flute count (3 for chip clearance) to your material and hole depth. The H6 tolerance ensures a precise fit. For extended reach applications, verify the tap's overall length meets your clearance requirements. Consult OSG's technical data for material-specific speeds and feeds.
