Osg 1005110508 Straight Flute Tap 6-32 Unc Ticn

Product Description

The OSG 1005110508 is a straight flute machine tap designed for cutting 6-32 UNC internal threads in hardened steel and alloy steel workpieces. It features a modified bottoming chamfer, making it well suited for threading blind holes where the thread must extend close to the bottom. Built from powdered metal and finished with a TiCN coating, this tap delivers increased wear resistance and heat tolerance compared to standard high-speed steel taps. With 4 flutes and an H3 thread limit, it produces a 2B class-of-fit thread. Overall length is 2 inches, and thread length is 0.374 inches. Installation is performed by qualified machinists or tool-and-die professionals.

This tap is rated for machine tapping applications in hardened steel and alloy steel. The modified bottoming chamfer allows threading closer to the bottom of blind holes than a standard plug or taper tap. It carries a right-hand thread direction and is part of OSG Series 10051. Typical use cases include production machining environments, repair shops, and maintenance operations requiring precise, repeatable 6-32 UNC threads in harder ferrous materials. The TiCN coating extends tool life in demanding cutting conditions.

Key Features

• Modified bottoming chamfer for threading near the bottom of blind holes
• TiCN coating improves wear resistance and reduces heat buildup during cutting
• Powdered metal construction for increased toughness over standard HSS
• 4 straight flutes suited for machine tapping in rigid setups
• H3 thread limit produces consistent 2B class-of-fit internal threads
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for machine tapping 6-32 UNC threads in hardened steel and alloy steel applications per OSG Series 10051 specifications.

Installation Notes

This tap is intended for use by machinists in CNC or manual tapping machines with a rigid or semi-rigid tapping setup. Power down all equipment and secure the workpiece before tool changes. Ensure the tap holder is aligned concentrically with the drilled pilot hole to prevent tap breakage. Follow applicable shop safety standards and manufacturer feed and speed recommendations for the specific workpiece material.
