Eagle Cutting Tool MT-270-300-B-I M27.0x3.00 Hss Metric Tap

Product Description

The EAGLE CUTTING TOOL MT-270-300-B-I is an M27.0x3.00 high-speed steel (HSS) metric bottom tap designed to cut full threads to the bottom of a blind hole. The bottom tap geometry features minimal chamfer on the leading threads, allowing thread cutting to proceed as close to the hole floor as possible. Weighing 0.97 pounds, this is a robust, full-size tap suited for production shops, maintenance facilities, and field repair work where metric threading in steel, cast iron, aluminum, and similar materials is required.

This tap is intended for use in M27 metric tapped holes with a 3.00 mm pitch. It is well-suited for threading through pre-drilled blind holes in structural components, machine frames, fixtures, and heavy equipment. The bottom tap is typically the final step in a three-tap sequence — following a taper tap and a plug tap — when full thread depth at the bottom of a blind hole is required. Machinists, millwrights, and maintenance technicians working in industrial and commercial environments will find this tap appropriate for hand tapping or low-speed machine tapping operations.

Key Features

• M27.0x3.00 thread form — standard metric coarse pitch
• High-speed steel (HSS) construction for hardness and wear resistance across common workpiece materials
• Bottom tap style allows threading to the floor of blind holes
• Weighs 0.97 pounds — full-size tap suitable for heavy-duty threading tasks
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a standard M27x3.00 metric bottom tap compatible with any workholding setup or tap wrench sized to accept the tap's square drive shank. Suitable for use in hand tapping or low-speed machine tapping applications requiring a metric coarse thread profile.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench or tapping fixture. Always ensure the workpiece is securely clamped and the tap is started square to the hole before applying torque. Use appropriate cutting fluid for the workpiece material to extend tap life and reduce the risk of breakage. For blind holes, clear chips frequently by reversing the tap to avoid chip packing at the bottom of the hole.
