Eagle Cutting Tool MT-025-045-B-I M2.5x0.45 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL MT-025-045-B-I is an M2.5x0.45 high-speed steel (HSS) metric bottom tap designed to cut internal threads to the bottom of blind holes. It produces a full thread profile as close to the bottom of a hole as the tap geometry allows, making it the right choice when thread depth is critical. At 0.09 pounds, this is a compact, lightweight tool suited for precision threading work in small-diameter applications. It is used by machinists, maintenance technicians, and skilled tradespeople working with metric-threaded fasteners.

This bottom tap is intended for threading M2.5 holes with a 0.45 mm pitch in materials suited to HSS tooling, including mild steel, aluminum, brass, and similar metals. It is commonly used in bench work, drill press operations, and manual tapping of small components where a plug or taper tap has already started the thread and a bottom tap is needed to finish threading to the base of a blind hole. Applications span general metalworking, HVAC equipment fabrication, electrical enclosure assembly, and light mechanical repair work.

Key Features

• M2.5x0.45 metric thread form for precise internal thread cutting
• Bottom tap geometry threads blind holes to maximum depth
• High-speed steel (HSS) construction provides hardness and wear resistance
• Lightweight at 0.09 pounds for easy handling in precision work
• Minimum order quantity of 1 unit allows single-piece purchase

Compatibility

Designed as a standard metric bottom tap for use in any application requiring M2.5x0.45 internal threads, compatible with standard tap wrench holders and machine tap holders sized for small-diameter taps.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians familiar with hand or machine tapping procedures. Ensure the workpiece is securely clamped before tapping. Use appropriate cutting fluid for the material being threaded to extend tool life and improve thread quality. A plug or taper tap should be used to start the thread before using this bottom tap in a blind hole.
