Eagle Cutting Tool HT-2500-28-P-I Hand Plug Tap 1/4-28

Product Description

The EAGLE CUTTING TOOL HT-2500-28-P-I is a 1/4-28 high-speed steel (HSS) hand plug tap designed for cutting internal threads in metal workpieces. The plug chamfer — typically 3 to 5 threads — makes this tap suited for through-holes and moderately deep blind holes where starting ease and thread continuity both matter. At 0.31 pounds, it is a lightweight single-piece tool handled by machinists, pipefitters, HVAC technicians, and maintenance mechanics who need accurate 1/4-28 UNF threads in the field or on the bench.

This tap is used wherever a 1/4-28 unified fine thread is required — common in HVAC equipment fasteners, instrumentation fittings, electrical enclosures, and general mechanical assemblies. The fine thread pitch provides good holding strength in thinner materials and hard alloys. It is suitable for hand tapping in a standard tap wrench on ferrous and non-ferrous metals. Import-grade tooling at this size is a standard choice for general maintenance and repair operations where high production volume is not a factor.

Key Features

• 1/4-28 UNF thread form for fine-pitch internal threading
• High-speed steel (HSS) construction provides wear resistance across common metals
• Plug chamfer style suits both through-holes and moderately deep blind holes
• Hand tap design for use with a standard tap wrench — no machine required
• Lightweight at 0.31 pounds for easy field carry and bench use

Compatibility

Designed as a standard hand plug tap for cutting 1/4-28 UNF internal threads in ferrous and non-ferrous metal workpieces across general maintenance, repair, and mechanical assembly applications.

Installation Notes

A licensed machinist or qualified maintenance technician should select the correct tap drill size for 1/4-28 UNF threads before starting. Secure the workpiece firmly and use a calibrated tap wrench to maintain perpendicular alignment with the hole. Apply cutting fluid appropriate to the workpiece material to extend tap life and reduce the risk of breakage. Back off the tap periodically to clear chips, especially in blind holes.
