Titan Usa TT90600 Straight Flute Tap 3/4-10 Unc

Product Description

The TITAN USA TT90600 is a straight flute hand tap designed for cutting 3/4-10 UNC right-hand internal threads in ferrous and non-ferrous materials. Built from high-speed steel with a bright/uncoated finish, this taper chamfer tap is part of the Series 725 line. It carries an H3 thread limit, making it suitable for tapping to a 2B or 3B class of fit. With 4 flutes and a taper chamfer, the tool guides itself into the workpiece gradually, reducing the risk of tap breakage during entry. Licensed machinists, tool-and-die makers, and maintenance technicians rely on this style of tap for general-purpose threading in production and repair environments.

This tap is suited for threading through-holes and blind holes where chip clearance is not a limiting factor. The taper chamfer distributes cutting load across the first 8 to 10 threads, making it a preferred starting tap when working with manual or machine tapping setups. It is appropriate for use in steel, cast iron, aluminum, and similar machinable materials in both shop and field maintenance applications.

Key Features

• 3/4-10 UNC thread form with right-hand thread direction
• Taper chamfer for gradual entry and reduced breakage risk
• H3 thread limit for 2B and 3B class of fit tolerance control
• High-speed steel construction for durability across a range of machinable materials
• Bright/uncoated finish — no coating buildup to affect thread tolerance
• 4-flute design provides good chip room in standard through-hole applications

Compatibility

Designed as a standard hand tap for general-purpose 3/4-10 UNC threading operations. Compatible with standard tap wrenches and machine tap holders sized for a 0.590-inch shank diameter.

Installation Notes

This tap is installed by licensed machinists or maintenance technicians using a tap wrench or appropriate machine holder. Always ensure the workpiece is securely clamped before tapping. Apply a suitable cutting fluid for the material being tapped to extend tool life and improve thread quality. Reverse the tap periodically during hand tapping to break chips and reduce the risk of binding.
