Osg 1306300608 Spiral Point Tap 10-32 Unf 3 Flute Plug

Product Description

The OSG 1306300608 is a spiral point plug tap designed for cutting right-hand internal threads to the 10-32 UNF standard. Built from powdered metal and finished with a V coating, this tap delivers consistent thread quality in a wide range of workpiece materials. The 3-flute spiral point geometry pushes chips forward ahead of the cut, making it well suited for through-hole threading applications. At 2.374 inches overall length with a 0.492 inch thread length, it fits standard tap holders and machines used in production and maintenance environments. The H3 thread limit and 2B class of fit meet common tolerance requirements for fastener assemblies in industrial and mechanical work.

This tap is intended for threading through holes in ferrous and non-ferrous metals. Rated material applications include titanium, hardened steel, cast iron, alloy steel, and stainless steel. It is used in machine shops, maintenance and repair operations, and production tooling setups where consistent UNF thread form is required. The V coating improves surface hardness and lubricity, reducing heat and extending tool life when cutting tougher alloys.

Key Features

• Spiral point geometry pushes chips forward, ideal for through-hole threading
• Powdered metal construction provides uniform hardness and wear resistance
• V coating reduces friction and heat buildup in hard materials
• H3 thread limit holds tight tolerance for 2B class of fit
• Right-hand cut, no coolant-through required
• Rated for titanium, hardened steel, cast iron, alloy steel, and stainless steel

Compatibility

Designed for threading 10-32 UNF through holes in titanium, hardened steel, cast iron, alloy steel, and stainless steel workpieces. Fits standard tap holders accepting a 0.194 inch shank diameter.

Installation Notes

This tap is installed by a machinist or maintenance technician using a standard tap holder or tapping head. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 10-32 UNF before threading. Apply cutting fluid appropriate for the workpiece material to prolong tool life. Follow shop safety procedures and machine lockout protocols before setting up or changing tooling.
