Osg 1105610508 Spiral Point Tap 6-32 Unc Ticn

Product Description

The OSG 1105610508 is a spiral point tap designed for threading 6-32 UNC holes in demanding materials. Built from powdered metal and coated with TiCN (titanium carbonitride), it delivers extended tool life in applications where standard high-speed steel taps wear quickly. The plug chamfer geometry guides thread engagement progressively from the start of the cut. At 2 inches overall length with an 11/16-inch thread length and a 0.141-inch shank diameter, this tap fits standard tap holders used in machine tapping operations. It cuts right-hand threads to a 2B class of fit with an H3 thread limit, producing clean, tolerance-consistent threads in production environments.

This tap is suited for machine tapping in CNC machining centers, drill presses, and tapping heads where controlled feed and rigid setup are used. The TiCN coating and powdered metal substrate make it appropriate for hardened steel, stainless steel, high-nickel alloys, titanium, and alloy steel. It is commonly used in aerospace, automotive, and industrial fabrication shops where these material groups appear in regular production. Licensed machinists and tool-and-die professionals are the primary users. The plug chamfer style requires a through-hole or adequate chip clearance for the lead threads to exit the cut zone.

Key Features

• TiCN coating improves wear resistance and reduces galling in stainless steel and high-nickel alloys
• Powdered metal construction provides higher hardness and toughness compared to standard M2 HSS
• Plug chamfer style with 3 flutes for efficient chip pushing in through-hole applications
• H3 thread limit maintains 2B class of fit across the full thread length
• Right-hand cut, no coolant-through requirement - compatible with flood or mist coolant setups
• Series 312TI designation - part of a standardized OSG tap family for consistent replacement sourcing

Compatibility

Designed for use in standard tap holders and collet chucks accepting a 0.141-inch shank diameter. Rated for threading hardened steel, stainless steel, high-nickel alloy, titanium, and alloy steel workpieces in 6-32 UNC through-hole applications.

Installation Notes

Machine tapping should be performed at speeds appropriate for the workpiece material and tap diameter - consult published feeds-and-speeds data for powdered metal taps in the target material. Secure the tap in a rigid holder or floating tap adapter to prevent misalignment and tap breakage. Ensure the drill hole is sized correctly for a 6-32 UNC tap prior to threading. Power down or de-energize the machine spindle and engage the E-stop before changing tooling.
