Eagle Cutting Tool MT-045-075-B-I M4.5x0.75 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL MT-045-075-B-I is an M4.5 x 0.75 high-speed steel (HSS) metric bottom tap designed to cut threads to the full depth of a blind hole. Bottom taps have minimal lead chamfer, allowing them to thread closer to the bottom of a hole than taper or plug taps. This tool is suited for production and repair threading operations in metal fabrication, maintenance, and machine shop environments. Licensed machinists and trade technicians working with metric-fastener assemblies will find this tap appropriate for precision threading tasks where thread depth is critical.

This tap is intended for use in blind-hole threading applications where a full thread form must be achieved near the base of the bore. It is appropriate for use in steel, aluminum, and similar machinable metals. Common applications include fabrication shops, HVAC equipment assembly, electrical enclosure manufacturing, and general mechanical repair where M4.5 x 0.75 metric fasteners are specified.

Key Features

• M4.5 x 0.75 metric thread form for standard metric fastener compatibility
• Bottom tap geometry with minimal lead chamfer for threading close to the bottom of blind holes
• High-speed steel (HSS) construction for durability in metal threading applications
• Lightweight at 0.09 pounds, reducing hand fatigue during extended use
• Minimum order quantity of 1, suitable for single-unit replacement or stocking

Compatibility

Designed as an import-grade HSS metric bottom tap for standard M4.5 x 0.75 thread cutting applications in blind holes across common machinable metals.

Installation Notes

This tap is installed by a machinist or qualified tradesperson using a tap wrench or tapping fixture. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct diameter for M4.5 x 0.75 threads before tapping. Apply appropriate cutting fluid to extend tool life and reduce heat buildup. Follow all relevant shop safety practices when operating cutting tools.
