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

Product Description

The EAGLE CUTTING TOOL HT-5000-13-B-I is a 1/2-13 high-speed steel (HSS) hand bottom tap designed for threading operations that require cutting threads to the bottom of a blind hole. The bottom chamfer geometry allows the tap to reach near the base of a hole with minimal unthreaded length remaining. At 0.31 pounds, it is a lightweight, single-piece tool suited for manual tapping by machinists, maintenance technicians, pipefitters, and general trade professionals working in metal fabrication or mechanical assembly applications.

This tap is appropriate for hand-tapping 1/2-13 UNC (Unified Coarse) threaded holes in mild steel, aluminum, cast iron, and similar machinable materials. It is commonly used in repair and maintenance scenarios where a blind-hole thread must be cut as deep as possible, such as tapping bolt holes in flanges, brackets, fixtures, or structural components. The import designation indicates sourcing from an offshore manufacturer while conforming to standard UNC thread form dimensions.

Key Features

• 1/2-13 UNC thread form for standard coarse-thread fastener compatibility
• Bottom chamfer geometry allows threading to the base of blind holes
• High-speed steel (HSS) construction provides hardness and wear resistance for hand tapping
• Lightweight at 0.31 pounds for easy single-hand use with a tap wrench
• Minimum order quantity of 1 unit — available for individual purchase

Compatibility

Designed as a standard 1/2-13 UNC hand bottom tap suitable for use with conventional tap wrenches and tapping guides in general machining and maintenance applications.

Installation Notes

A licensed machinist or qualified tradesperson should ensure the workpiece is properly secured before tapping. Use the appropriate cutting fluid or tapping compound for the material being threaded to reduce friction and extend tap life. Back the tap out periodically to clear chips and prevent binding or breakage. Never force a tap — if resistance increases sharply, back off and clear chips before continuing.
