Osg 1023700 Straight Flute Tap 6-32 Unc Plug 2B Hss

Product Description

The OSG 1023700 is a straight flute tap designed for cutting 6-32 UNC internal threads in a wide range of ferrous and non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, it features 3 flutes and a plug chamfer for standard through-hole and shallow blind-hole tapping applications. The H3 thread limit provides a controlled tolerance fit for 2B class threads, making it a reliable choice for production and maintenance tapping work. Overall length is 2 inches with a thread length of 11/16 inches, keeping the tool compact and easy to handle in a standard tap wrench or machine holder.

This tap is suited for use in manual hand-tapping setups, drill press operations, and CNC tapping cycles where a straight-flute design is appropriate. The plug chamfer style - with a moderate lead-in of several threads - works well for through-holes and holes with sufficient clearance below the thread. Listed material applications include aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel, covering the majority of general machining and maintenance scenarios encountered by machinists, tool and die technicians, and industrial maintenance professionals.

Key Features

• 6-32 UNC thread form with right-hand thread direction
• 3-flute straight flute geometry for chip clearance in moderate-depth holes
• Plug chamfer for versatile use in through-holes and open blind holes
• H3 thread limit for consistent 2B class of fit tolerance
• High-speed steel construction for good wear resistance across listed materials
• Bright, uncoated finish - suitable where coating is not required by the application

Compatibility

Designed for tapping 6-32 UNC threads in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. Part of OSG Series 102.

Installation Notes

Always secure the workpiece before tapping and ensure the tap is properly aligned to avoid thread distortion or tap breakage. Use an appropriate cutting fluid for the material being tapped, particularly with steel and cast iron. Power down any machine tool and follow lockout/tagout procedures before changing or inspecting taps in a machine holder. Replace worn taps promptly - a dull tap in hard materials is a common cause of breakage.
