Osg 1050700 Straight Flute Tap 10-24 Unc Hss Plug

Product Description

The OSG 1050700 is a straight flute plug tap designed for threading 10-24 UNC internal threads in a wide range of ferrous and non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, it produces right-hand threads to a 2B/3B class of fit with an H3 thread limit. The plug chamfer distributes cutting load across the first few threads, making it well-suited for through-hole tapping applications. With an overall length of 2.375 inches and a thread length of 0.875 inches, it fits standard tap holders and tapping heads used in machine shop and production environments. Licensed machinists, tool and die makers, and maintenance technicians are the primary installers of this tool.

This tap is intended for use in through-hole and open-ended tapping operations on aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It performs in both hand tapping and machine tapping setups. The 3-flute straight flute geometry provides chip evacuation suited to softer materials and shorter chip-producing metals. Its compact profile fits standard 10-24 tap holders used in drill presses, CNC machining centers, and manual tapping arms.

• Neck length of 1.4724 inches provides clearance in deeper through-hole setups

Compatibility

Compatible with aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces. Fits standard tap holders and machine tapping collets sized for 10-24 hand taps with a 0.194-inch shank diameter.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench, tapping head, or machine spindle. Always use a cutting fluid or tapping compound appropriate for the workpiece material to extend tool life and improve thread finish. Ensure the workpiece is securely fixtured before tapping to prevent tap breakage. Follow shop safety standards and OSHA machine guarding requirements when using in powered tapping equipment.
