Eagle Cutting Tool MT-022-045-B-I Hss Metric Bottom Tap

Product Description

The EAGLE CUTTING TOOL MT-022-045-B-I is an M2.2x0.45 high-speed steel (HSS) metric bottom tap designed for threading blind holes to their full depth. As a bottom tap, it produces threads closer to the bottom of a hole than taper or plug taps allow, making it the finishing step in precision metric tapping operations. Weighing 0.09 pounds, this compact tap is suited for detail work in small-diameter applications where thread quality and depth are critical. Machinists, toolmakers, and maintenance technicians rely on this style of tap when working in confined or depth-restricted bores.

This tap is used in metalworking and machining environments where M2.2x0.45 metric threads are required in blind holes. Typical applications include precision instrument manufacturing, electronics hardware, small-fastener assemblies, and repair work on metric-threaded components. It is appropriate for use in hand tapping operations or with low-speed tapping machines when controlled feed and torque are maintained.

Key Features

• Bottom tap geometry threads blind holes to near-full depth
• M2.2x0.45 metric thread form for precise, standard-compliant threads
• High-speed steel (HSS) construction provides wear resistance and durability across a range of metals
• Lightweight at 0.09 pounds, suited for fine detail and small-bore work
• Minimum order quantity of 1, available as a single-unit purchase

Compatibility

Designed as an OEM-style replacement or direct-use metric bottom tap for M2.2x0.45 thread applications in hand tapping and light machine tapping setups.

Installation Notes

Bottom taps should be used as the final step after a taper or plug tap has already started the thread in the workpiece. Secure the workpiece firmly before tapping and apply appropriate cutting fluid to extend tap life and improve thread finish. Use a calibrated tap wrench or low-speed tapping machine and advance with steady, controlled torque to avoid breakage in small-diameter taps. Inspect the hole depth and tap engagement before each use to prevent bottoming out and tap breakage.
