Osg 1737101 Spiral Point Tap 6-32 Unc 2 Flute Plug

Product Description

The OSG 1737101 is a spiral point plug tap designed for threading 6-32 UNC holes in a range of ferrous materials. Manufactured from vanadium high speed steel with a steam oxide coating, this tap resists heat buildup and provides lubricity during the cutting cycle. It features 2 flutes, a plug chamfer, and an H5 thread limit for consistent tolerance control. With an overall length of 2 inches and a thread length of 0.377 inches (11/16 inches), it is sized for standard machine tap holders and CNC tapping heads. Right-hand thread direction. Licensed machinists, maintenance technicians, and tool-and-die professionals use this tap in production and job-shop environments.

The OSG 1737101 is suited for tapping 6-32 UNC threads in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel. The spiral point geometry pushes chips forward ahead of the cut, making it a reliable choice for through-hole tapping operations on CNC machining centers, drill presses, and manual tapping arms. The steam oxide finish helps reduce built-up edge, which is especially useful when working with low-carbon and medium-carbon steels at moderate feed rates.

Key Features

• 6-32 UNC thread form with H5 thread limit for tight tolerance control
• Spiral point geometry drives chips forward, optimized for through-hole applications
• Vanadium high speed steel construction handles interrupted cuts and work-hardening materials
• Steam oxide coating reduces friction and resists heat during tapping
• Plug chamfer provides a gradual lead-in for starting accuracy
• Right-hand cut, no coolant-through, non-interrupted thread design

Compatibility

Compatible with hardened steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces requiring 6-32 UNC through-hole threads. Fits standard quick-change tap holders and collet chucks sized for a 0.141-inch shank diameter.

Installation Notes

Install and remove taps using appropriate tap wrenches or machine holders rated for the shank diameter. Secure the workpiece fully before beginning the tapping cycle to prevent tap breakage. Apply a cutting fluid suitable for the workpiece material, particularly when tapping stainless steel or hardened steel. Follow OSHA machine guarding requirements and the equipment manufacturer guidelines when operating power tapping equipment.
