Osg 1320000 Spiral Point Tap 00-90 Uns 2 Flute Hss

Product Description

The OSG 1320000 is a spiral point tap designed for cutting internal threads in a wide range of materials. Built to a 00-90 UNS thread standard with a plug chamfer, this tap drives chips forward ahead of the cutting edge, keeping the flute area clear during through-hole tapping. Manufactured from high-speed steel with a bright finish, it features 2 flutes, a right-hand thread direction, and an H2 thread limit for consistent tolerance control. Overall length is 1.73 inches, with a thread length of 0.25 inches and a shank diameter of 0.141 inches. It weighs approximately 0.008 pounds.

This tap is suited for threading miniature through-holes in a broad range of workpiece materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The plug chamfer style makes it a practical choice for production and repair tapping operations where through-hole access is available. It is categorized under the S111 series and is sold individually.

Installation Notes

Tap installation and operation should be performed by a qualified machinist or tooling technician. Ensure the workpiece is properly secured and the spindle is aligned before engaging the tap. Power down or lock out any machine tool before installing or removing the tap from the holder. Do not use this plug chamfer tap in blind holes without confirming adequate chip clearance, as spiral point taps are optimized for through-hole applications.
