Eagle Cutting Tool HT-30000-8-B-I Hss Hand Bottom Tap

Product Description

The EAGLE CUTTING TOOL HT-30000-8-B-I is a high-speed steel (HSS) hand bottom tap designed for threading operations that require cutting threads to the very bottom of a blind hole. With a 3-inch diameter and 8 threads per inch (TPI), this tap handles large-diameter threading tasks common in heavy industrial, mechanical, and structural applications. The bottom tap profile allows full thread engagement up to the floor of a blind bore. Machinists, maintenance technicians, and pipe fitters working with large-diameter threaded connections rely on this style of tap when other tap styles cannot complete the thread depth required.

This tap is suited for use in metalworking, maintenance and repair operations (MRO), and fabrication environments where oversized or coarse-thread bottoming work is required. The 3 inch - 8 TPI specification is a coarse unified national coarse (UNC) thread form frequently encountered in heavy equipment repair, structural fastening, and large fixture work. It is intended for hand tapping use with a standard tap wrench.

Key Features

• Bottom tap geometry allows threading to the full depth of blind holes
• High-speed steel (HSS) construction provides hardness and wear resistance for threading steel and other common metals
• 3 inch diameter with 8 TPI coarse thread form for large-diameter fastener applications
• Designed for hand tapping use with a tap wrench
• Import grade offering a cost-effective option for general MRO and fabrication use

Compatibility

Designed as an OEM-style hand bottom tap for use in large-diameter blind-hole threading applications requiring a 3 inch - 8 TPI coarse thread form.

Installation Notes

This tap is intended for use by machinists or qualified tradespeople familiar with hand tapping procedures. Always secure the workpiece before tapping and use the appropriate tapping fluid for the material being threaded. Back the tap out periodically to clear chips and prevent binding or breakage. Do not use with power tools unless the tap is rated for machine use.
