Eagle Cutting Tool HT-6875-11-T-I Hss Hand Taper Tap 11/16-11

Product Description

The EAGLE CUTTING TOOL HT-6875-11-T-I is a high-speed steel (HSS) hand taper tap sized 11/16-11 UNC. It is designed to cut internal threads in metal workpieces by hand, starting the thread with a gradual taper entry that aligns easily and reduces torque during initial engagement. The taper lead typically spans 8 to 10 threads, making it the correct starting tap for through-holes and the first pass on blind holes. Machinists, pipefitters, and maintenance technicians working in fabrication, repair, or field service applications reach for this tap when cutting 11/16-inch, 11-threads-per-inch coarse threads by hand.

This tap is suited for threading operations in steel, cast iron, aluminum, and similar machinable materials. The 11/16-11 UNC thread form is a coarse-series designation commonly found in structural fasteners, heavy equipment components, and industrial machinery. It is appropriate for both job shop and maintenance-and-repair (MRO) environments where occasional hand-tapping is required. The import-grade construction keeps the cost practical for shops that need a reliable working tap without specialty tooling budgets.

Key Features

• HSS construction provides hardness and wear resistance suitable for tapping steel and non-ferrous metals
• Taper chamfer entry eases thread starting and reduces tap breakage during hand use
• 11/16-11 UNC thread form cuts standard coarse-series internal threads
• Sized for use with a standard tap wrench — no machine spindle required
• Minimum order quantity of 1, suitable for single-unit procurement

Compatibility

Designed as a hand taper tap for cutting 11/16-11 UNC internal threads. Compatible with standard tap wrenches that accept the appropriate square drive shank for this tap size.

Installation Notes

Secure the workpiece firmly before tapping to prevent movement during thread cutting. Apply cutting fluid or tapping oil to the tap and workpiece to reduce friction, improve thread finish, and extend tap life. Back the tap off a half turn periodically to break chips and clear the flutes, especially in blind holes. Inspect the tap for wear or cracks before each use — a damaged tap can seize in the workpiece and be difficult to extract.
