Eagle Cutting Tool HT-356-T-I 3-56 Hss Hand Taper Tap

Product Description

The EAGLE CUTTING TOOL HT-356-T-I is a 3-56 high-speed steel (HSS) hand taper tap designed for cutting internal threads in ferrous and non-ferrous materials. The taper chamfer on this tap eases thread starting, making it the standard choice for initiating a thread in a through-hole or a blind hole with sufficient depth. At 0.31 pounds, it is a lightweight, hand-held tool suited for bench work, field repair, and light production threading. Licensed trades including electricians, HVAC technicians, and plumbers use taps like this when replacing or securing small-diameter fasteners in equipment panels, junction boxes, and mechanical assemblies.

The HT-356-T-I is suited for threading 3-56 UNC holes in both shop and field applications. It performs in materials such as aluminum, mild steel, brass, and plastic. The taper lead allows the tool to be started square in a drilled hole with minimal tendency to cross-thread, making it a reliable choice for precision work on small components and control enclosures typical in HVAC, electrical, and plumbing service environments.

Key Features

• 3-56 UNC thread form for small-diameter internal threading applications
• High-speed steel (HSS) construction provides hardness and wear resistance across a range of workpiece materials
• Taper chamfer lead simplifies thread starting and reduces the risk of tap breakage
• Lightweight at 0.31 pounds for easy single-hand use and portability
• Minimum order quantity of 1, suitable for individual service technicians or shop restocking

Compatibility

Designed as a standard 3-56 UNC hand taper tap compatible with any pre-drilled hole requiring 3-56 internal threads in metallic or plastic substrates.

Installation Notes

This tap is intended for use by machinists, maintenance technicians, and trade professionals performing manual threading operations. Always use a proper tap handle or T-handle wrench sized for small taps to avoid breakage. Apply cutting fluid appropriate for the workpiece material before tapping, and advance the tap with periodic back-turns to break chips and clear flutes. Secure the workpiece firmly before threading to maintain alignment and prevent tap breakage.
