Value Collection JY63328603 Spiral Point Tap 3/4-10 Unc

Product Description

The VALUE COLLECTION JY63328603 is a spiral point tap designed for threading 3/4-10 UNC holes in metal workpieces. Sometimes called a gun tap, the spiral point geometry pushes chips forward ahead of the cutting zone rather than packing them into the flutes, making it well-suited for through-hole tapping operations. Built from high speed steel (HSS) with a bright uncoated finish, this tap carries a plug chamfer with 3 to 5 leading threads to distribute cutting load on entry. The H11 thread limit designates a slightly oversized tolerance class, producing threads that accommodate standard plated fasteners or mating parts that require a small amount of additional clearance.

This tap is used in general machining, maintenance, and repair applications wherever a 3/4-10 UNC thread is required in a through-hole. It is appropriate for use in steel, cast iron, aluminum, and similar machinable materials. The plug chamfer makes it a practical choice for production tapping in a drill press, CNC machining center, or tapping arm where the workpiece has sufficient clearance on the exit side. Machinists, toolroom technicians, and maintenance mechanics in industrial and manufacturing environments are the typical users.

Key Features

• Spiral point (gun tap) geometry pushes chips forward for clean through-hole tapping
• 3/4-10 UNC thread form, right-hand cut
• 3 flutes with plug chamfer for gradual thread engagement on entry
• H11 thread limit — oversize by 0.0050 inches for plated-fastener fitment
• High speed steel construction for durability across a range of machinable materials
• Bright uncoated finish — no coolant-through requirement

Compatibility

Designed as a standard replacement or spare for applications requiring a 3/4-10 UNC spiral point plug tap with H11 thread limit in HSS. Fits standard tap holders and tapping chucks sized for 3/4-inch shank taps.

Installation Notes

Secure the workpiece firmly and ensure the through-hole is properly drilled and deburred before tapping. Use a suitable cutting fluid or tapping compound appropriate for the workpiece material to extend tap life and improve thread quality. Align the tap perpendicular to the workpiece surface to avoid thread distortion or tap breakage. Inspect the tap for wear or chipping before each use and replace if cutting edges show damage.
