Eagle Cutting Tool HT-6875-16-B-I Hss Bottom Tap 11/16-16

Product Description

The EAGLE CUTTING TOOL HT-6875-16-B-I is a high-speed steel (HSS) hand bottom tap designed to cut full threads to the bottom of a blind hole. The 11/16 inch diameter, 16 threads-per-inch (TPI) UNC thread form makes this tap a practical choice for threading tasks in maintenance, repair, and fabrication work. Weighing 0.31 pounds, it is a lightweight tool sized for hand-driven operation with a standard tap wrench. Machinists, pipefitters, millwrights, and general trade professionals use bottom taps when a plug or taper tap has already started the thread and full thread depth is required at the hole bottom.

This bottom tap is suited for threading ferrous and non-ferrous metals, plastics, and similar machinable materials in both shop and field environments. It is commonly used in maintenance and repair operations where threaded inserts, fasteners, or fittings must seat completely at the base of a blind hole. The 11/16 inch - 16 TPI specification positions this tap for medium-to-large fastener work in structural, mechanical, and fabrication applications.

Key Features

• High-speed steel (HSS) construction provides hardness and wear resistance for hand tapping operations
• Bottom tap style allows threading to the full depth of blind holes where plug or taper taps cannot finish the thread
• 11/16 inch diameter with 16 TPI thread form for medium-to-large fastener applications
• Lightweight at 0.31 pounds, suitable for hand-wrench operation
• Import grade offers a cost-effective option for general-purpose threading tasks

Compatibility

Designed as an OEM-style replacement or standard hand bottom tap for use with conventional tap wrenches sized for 11/16 inch - 16 TPI threading applications.

Installation Notes

Bottom taps are typically the third tap used in a hand-tapping sequence, following a taper tap and a plug tap to establish and extend the thread before finishing at the hole base. Always apply appropriate cutting fluid to reduce friction and extend tap life when working with metals. Use a calibrated tap wrench and advance the tap in short increments, backing off periodically to break chips. Secure the workpiece firmly before tapping to maintain thread alignment.
