Eagle Cutting Tool HT-5000-13-B-D 1/2-13 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL HT-5000-13-B-D is a 1/2-13 UNC high-speed steel (HSS) hand bottom tap manufactured in the USA. Bottom taps are ground with minimal chamfer on the leading threads, allowing the cutting edge to reach the bottom of a blind hole and produce full threads along nearly the entire depth of the tapped bore. This tool is designed for hand tapping operations and is the finishing tap of choice when thread depth must be maximized in a stopped hole. At 0.32 pounds, it is lightweight enough for single-hand use with a standard tap wrench.

The HT-5000-13-B-D is suited for threading ferrous and non-ferrous materials in maintenance, repair, fabrication, and light production environments. Plumbers, pipefitters, HVAC technicians, electricians, and general fabricators reach for a bottom tap when finishing blind holes in fixtures, brackets, flanges, or equipment frames where a plug or taper tap cannot deliver full threads to the required depth. It is appropriate for use in both shop and field service settings wherever 1/2-13 UNC fastener threads are required.

Key Features

• 1/2-13 UNC thread form for use with standard 1/2-13 fasteners
• High-speed steel construction maintains cutting edge hardness under friction and heat
• Bottom chamfer geometry threads blind holes to near-full depth
• USA manufactured for consistent ground tolerances and tool integrity
• Lightweight at 0.32 pounds for comfortable hand tapping with a tap wrench or T-handle

Compatibility

Designed as a standard hand bottom tap for any application requiring 1/2-13 UNC internal threads. Compatible with conventional tap wrenches and T-handle drivers sized for the square drive shank of a 1/2-13 tap.

Installation Notes

A licensed machinist, pipefitter, plumber, or qualified technician should select the correct tap drill size for 1/2-13 UNC before beginning the tapping operation. Always start the hole with a taper or plug tap to establish thread alignment before using the bottom tap to finish the bore. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Secure the workpiece fully before tapping and advance the tap in short increments, backing off periodically to break the chip.
