Osg 1014900 Straight Flute Tap 10-24 Unc Plug Hss

Product Description

The OSG 1014900 is a straight flute plug tap designed for cutting internal threads in a range of ferrous and non-ferrous materials. It is ground to a 10-24 UNC thread profile with a right-hand thread direction and an H2 thread limit, making it suitable for applications requiring close tolerance fits. The tap features four flutes and a plug chamfer, which provides a balance between starting ease and thread engagement. With a bright uncoated finish and high-speed steel construction, this tap is built for general-purpose machine and hand tapping operations performed by machinists, maintenance technicians, and trade professionals.

This tap is appropriate for production and maintenance tapping in both shop and field settings. It handles threading in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. The plug chamfer style makes it a practical choice for through-hole tapping where the tap can pass through the full depth of the hole. It is sold individually and is part of the OSG Series 102 tap line.

Key Features

Compatibility

Designed for use in any tapping application requiring a 10-24 UNC plug tap, including aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping handle, or CNC tapping head. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for 10-24 UNC threads before tapping. Apply an appropriate cutting fluid or tapping compound to extend tool life and improve thread quality. Back the tap out periodically during hand tapping to break chips and reduce the risk of tap breakage.
