Eagle Cutting Tool HT-6250-11-P-D 5/8-11 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-6250-11-P-D is a 5/8-11 high-speed steel (HSS) hand plug tap manufactured in the USA. It is designed to cut internal threads in through-holes and blind holes by hand using a tap wrench or T-handle. The plug chamfer — typically 3 to 5 threads — allows the tap to start cleanly and progress through the workpiece with controlled torque. HSS construction provides the hardness and wear resistance needed to thread steel, cast iron, aluminum, and other common shop materials. This tap is used by machinists, pipefitters, maintenance mechanics, and millwrights working on fabrication, repair, and assembly tasks.

The HT-6250-11-P-D suits applications where a 5/8-inch diameter, 11-threads-per-inch (UNC) internal thread is required. It is well suited for general metalworking, MRO maintenance, structural fabrication, and machine shop operations. The plug-style chamfer makes it the most versatile choice for most threading jobs, working effectively in both through-holes and moderately deep blind holes. USA manufacture indicates compliance with standard ASME B94.9 tap geometry commonly specified in industrial and government procurement.

Key Features

• 5/8-11 UNC thread form for standard unified coarse-thread applications
• High-speed steel (HSS) construction for hardness and extended tool life
• Plug chamfer provides a balance of easy starting and threading depth capability
• Hand tap design for use with tap wrenches and T-handle drivers
• USA manufactured to standard ASME tap geometry

Compatibility

Designed as a standard hand plug tap for use in any application requiring a 5/8-11 UNC internal thread in metallic or non-metallic workpieces.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a calibrated tap wrench or T-handle. The workpiece should be secured in a vise before tapping begins, and the correct tap drill size for 5/8-11 UNC should be used to prepare the hole prior to tapping. Apply a suitable cutting fluid appropriate to the workpiece material to reduce friction and extend tap life. Back the tap off periodically to break chips and prevent binding, especially in blind holes.
