Regal Cutting Tools 030010TC Spiral Point Tap 5/8-11 Unc

Product Description

The REGAL CUTTING TOOLS 030010TC is a spiral point tap designed for threading 5/8-11 UNC through-holes in production and maintenance machining environments. Built from Hi Vanadium M7 high speed steel with an oxide finish, this tap delivers consistent thread quality in ferrous metals and alloy steels. It features a plug chamfer, 3 flutes, a 2B class of fit, and an H5 thread limit - specifications that make it well-suited for general-purpose tapping where dimensional accuracy and tool life are both priorities. Overall length is 3.8125 inches with a thread length of 1-3/32 inches.

This tap is intended for right-hand threading in through-hole applications where a spiral point design pushes chips forward and out of the cutting zone. It is used in machine tapping setups on CNC machining centers, drill presses, and tapping machines across metalworking, fabrication, and maintenance repair operations. The Triple Crown series targets high-performance tapping in production runs where reliability and thread consistency are required. Coolant-through is not available on this tap, making it suited to flooded or dry tapping setups depending on material and machine capability.

Key Features

• 5/8-11 UNC thread size with H5 thread limit for controlled tolerance fitment
• Hi Vanadium M7 high speed steel construction for improved wear resistance over standard M2
• Oxide finish provides mild corrosion resistance and reduces galling during cutting
• Plug chamfer (3-5 thread lead) suits through-hole machine tapping applications
• Spiral point geometry pushes chips ahead of the tap, reducing chip packing in through-holes
• 2B class of fit meets standard UNC thread tolerance requirements for most fastener and assembly applications

Compatibility

Designed as a standard-geometry replacement or direct-use spiral point tap for 5/8-11 UNC through-hole tapping applications in machine tapping setups consistent with the Triple Crown series specifications.

Installation Notes

This tap is intended for use by machinists and metalworking professionals in machine tapping operations. Secure the tap in a rigid or floating tap holder appropriate for the machine type before use. Ensure the workpiece is fixtured securely and the spindle speed and feed rate are set per the material being tapped. Never reverse a tap under load without confirming the machine setup supports it, and inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.
