YG-1 J1243 Spiral Point Tap 6-32 Unc Tin Vanadium Hss

Product Description

The YG-1 J1243 is a spiral point tap designed for cutting right-hand internal threads in through-hole applications. It produces a 6-32 UNC thread form using a 2-flute, plug-chamfer geometry that pushes chips forward ahead of the cutting zone, keeping the flutes clear during operation. The body is machined from vanadium high-speed steel and finished with a titanium nitride (TiN) coating that extends surface hardness and wear resistance. The H3 thread limit holds a 2B class of fit, making it suitable for standard fastener assemblies where moderate tolerance control is required. Licensed machinists and maintenance technicians are the typical installers of this tooling.

This tap is suited for light-duty threading operations in ferrous and non-ferrous materials where through-hole access allows chips to evacuate forward. The 6-32 UNC size is common in electrical enclosures, control panels, instrument housings, and light structural assemblies. The plug chamfer - typically 3 to 5 threads of lead - makes it appropriate for starting in a drilled hole with standard setup. It is sold individually and intended for use in hand tapping or low-torque machine tapping applications.

Key Features

• 6-32 UNC thread form, right-hand cutting direction
• 2-flute spiral point geometry pushes chips forward in through-hole work
• Plug chamfer for standard hole-entry starts
• Vanadium high-speed steel construction for toughness and edge retention
• TiN coating increases surface hardness and reduces friction at the cutting edge
• H3 thread limit, 2B class of fit for standard fastener tolerance requirements

Compatibility

Designed as a direct-use spiral point tap for through-hole tapping of 6-32 UNC threads in typical machining, maintenance, and fabrication applications where a 2B class of fit is specified.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or low-torque CNC tapping attachment. Always drill the correct tap drill diameter for a 6-32 UNC thread before tapping to avoid tool breakage. Use cutting fluid appropriate to the workpiece material. This tap does not support coolant-through delivery and should not be forced into blind holes where chip packing is a concern.
