Osg 1728101 Spiral Point Tap 10-32 Unf 3 Flutes

Product Description

The OSG 1728101 is a spiral point plug tap designed for cutting 10-32 UNF threads in a wide range of ferrous materials. Built from Vanadium High Speed Steel (HSS-E) with a steam oxide finish, this tap delivers reliable performance in production and maintenance threading applications. The spiral point geometry pushes chips forward ahead of the cutting action, reducing chip clogging in through-hole threading. With 3 flutes, an H7 thread limit, and a right-hand thread direction, this tap is suited for use in hand tapping setups and CNC or drill press applications where consistent thread quality is required.

This tap is intended for threading through-holes in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel. It is commonly used in metal fabrication shops, maintenance and repair operations, and production machining environments. The plug chamfer provides a gradual lead-in, making it suitable for starting threads from the top of a through-hole. Machinists, tool and die technicians, and maintenance mechanics are the primary installers of this type of tooling.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole threading
• Vanadium High Speed Steel (HSS-E) construction for improved wear resistance over standard HSS
• Steam oxide coating reduces friction and improves lubrication retention
• H7 thread limit for standard tolerance threading applications
• Plug chamfer provides controlled thread lead-in
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for cutting 10-32 UNF right-hand threads in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces via through-hole applications.

Installation Notes

This tap should be installed in a proper tap holder or collet chuck to maintain axial alignment during cutting. Always apply cutting fluid appropriate for the workpiece material before and during the threading operation. Secure the workpiece fully before tapping to prevent movement. Follow standard shop safety practices and machine guarding requirements when operating power tapping equipment.
