Osg 1005910200 Straight Flute Tap 10-32 Unf Bottoming

Product Description

The OSG 1005910200 is a solid carbide straight flute tap designed for cutting internal threads in a wide range of materials. Built to the 10-32 UNF thread standard with a bottoming chamfer, it produces threads close to the bottom of blind holes where standard or plug chamfer taps cannot reach. The 4-flute geometry provides rigidity and chip control, while the bright uncoated finish suits applications where coating buildup could affect tolerances. At 2.375 inches overall length with a 0.500-inch thread length, it is sized for machine tapping operations in production and maintenance environments. Installation and use require a licensed machinist or skilled toolroom technician.

This tap is suited for machine tapping in both production shop and maintenance repair environments. It performs in blind-hole applications where full thread depth is required near the bottom of the hole. Rated for use in aluminum, cast aluminum, cast iron, cobalt chrome, and copper alloy workpieces, it fits applications across aerospace, automotive, and general metalworking. The right-hand thread direction and 2B class of fit align with standard UNF fastener and component specifications commonly found in these industries.

Key Features

• Bottoming chamfer enables threading to the bottom of blind holes
• Solid carbide construction provides wear resistance and rigidity in hard and abrasive materials
• 4 straight flutes for chip management in through and shallow blind holes
• 10-32 UNF thread form with 2B class of fit for standard tolerance applications
• Bright uncoated finish suitable for aluminum and copper alloy applications
• No coolant-through requirement simplifies setup on standard machine tools

Compatibility

Designed for machine tapping operations requiring a 10-32 UNF bottoming tap in aluminum, cast aluminum, cast iron, cobalt chrome, and copper alloy workpieces per Series 10059 specifications.

Installation Notes

This tap is intended for use in a machine tapping setup such as a CNC machining center, drill press, or tapping machine with appropriate torque control. Ensure the spindle is fully stopped and the machine is powered down before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Do not exceed the tap's rated material application range, as solid carbide is brittle and susceptible to breakage under side loading or misalignment.
