Eagle Cutting Tool MT-080-125-T-I M8x1.25 Hss Metric Taper Tap

Product Description

The EAGLE CUTTING TOOL MT-080-125-T-I is an M8 x 1.25 high-speed steel (HSS) metric taper tap designed for cutting internal threads in through-holes and blind holes. The taper lead — typically 8 to 10 threads of gradual entry — distributes cutting load across multiple teeth, making thread starts easier and reducing the risk of tap breakage in harder materials. At 0.09 pounds, this is a compact, hand-held or machine-compatible tap suited for use in steel, aluminum, cast iron, and similar metals. Plumbers, HVAC technicians, electricians, and general trade professionals reach for this size when threading metric fastener holes in equipment enclosures, brackets, and mechanical assemblies.

The M8 x 1.25 thread form is a standard coarse-pitch metric size found throughout commercial HVAC equipment, pump housings, electrical panel hardware, and plumbing fixture mounting components. This tap is appropriate for both bench work and light CNC or drill-press tapping operations where a taper-start is preferred over a plug or bottoming tap. It is particularly useful when initiating threads in a new hole before following with a plug tap to thread closer to the bottom of a blind bore.

Key Features

• M8 x 1.25 metric coarse-pitch thread form for wide compatibility with standard metric fasteners
• High-speed steel (HSS) construction provides hardness and heat resistance during cutting
• Taper lead design distributes cutting force for easier thread starts and reduced breakage risk
• Lightweight at 0.09 pounds — easy to handle in confined or overhead installation work
• Minimum order quantity of 1 — available as a single-piece purchase

Compatibility

Designed as a standard metric taper tap for use in any application requiring M8 x 1.25 internal threads. Suitable for hand tapping with a tap wrench or machine tapping on drill presses and tapping heads.

Installation Notes

Always use the correct tap drill size for an M8 x 1.25 thread before starting the tap. Apply cutting fluid or tapping compound appropriate for the workpiece material to reduce heat and extend tap life. Secure the workpiece firmly and back the tap off periodically to break chips, especially in blind holes. Follow applicable shop safety practices and wear eye protection during all tapping operations.
