Osg 1305711008 Spiral Flute Tap 10-24 Unc Ticn

Product Description

The OSG 1305711008 is a spiral flute tap designed for threading 10-24 UNC holes in demanding materials. Built from powdered metal and finished with a TICN (Titanium Carbon Nitride) coating, it delivers extended tool life in abrasive and hard-to-machine applications. The modified bottoming chamfer allows threading close to the bottom of blind holes. With a right-hand flute direction, H3 thread limit, and a 10-degree helix angle, this tap is engineered for consistent chip evacuation and accurate thread form in production environments. It is part of the OSG EXOTAP VC-10TI series.

This tap is suited for threading operations in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. The spiral flute geometry pulls chips up and out of the hole, making it effective in blind-hole applications across CNC machining centers and manual tapping operations. The 2B and 3B class of fit covers a broad range of standard fastener thread tolerances used in aerospace, automotive, and general industrial work.

Key Features

• 10-24 UNC thread form with right-hand thread direction and H3 thread limit
• Modified bottoming chamfer for threading near the bottom of blind holes
• TICN coating increases surface hardness and reduces friction for longer tool life
• Powdered metal substrate provides uniform grain structure and wear resistance
• 3 spiral flutes with 10-degree helix angle for efficient chip evacuation
• Rated for use in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys

Compatibility

Designed for 10-24 UNC blind and through-hole tapping applications in materials including alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. Part of the OSG EXOTAP VC-10TI series (Series 313TI).

Installation Notes

Installation is performed by machinists and tooling technicians using CNC tapping cycles or manual tap handles with appropriate torque control. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole. Use a cutting fluid or tapping compound rated for the workpiece material to protect both the tap and the freshly cut threads. Inspect thread form periodically using a go/no-go gauge to verify 2B or 3B class of fit compliance.
