Hertel K014514AS Spiral Point Tap 8-32 Unc 2 Flute Hss

Product Description

The HERTEL K014514AS is a spiral point tap designed for cutting 8-32 UNC internal threads in through-hole applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this plug-chamfer tap drives chips forward ahead of the cutting action, making it well suited for production threading on CNC machining centers, drill presses, and tapping arms. The tap features a 2-flute design with a right-hand thread direction and carries an H11 thread limit, which provides a slight oversize of 0.005 inches to accommodate plating allowances or tighter fit classes. Overall length is 2.0 inches.

This tap is used in metalworking and fabrication environments where through-hole 8-32 UNC threads are required in materials compatible with high-speed steel cutting tools. It is commonly installed by machinists and tool-and-die technicians in job shops, manufacturing facilities, and maintenance departments. The plug chamfer makes it the standard choice when starting a tap in a through-hole or when a moderate lead-in is needed for efficient chip flow and threading speed.

Key Features

• 8-32 UNC thread form for standard unified coarse-pitch through-hole threading
• High-speed steel construction provides durability across a range of ferrous and non-ferrous workpiece materials
• Plug chamfer (3-5 threads) enables efficient chip evacuation in through-hole applications
• H11 thread limit with 0.005-inch oversize accommodates plating or tight tolerance fitment requirements
• 2-flute spiral point geometry pushes chips forward ahead of the tap during cutting
• Bright, uncoated finish suitable for use with standard cutting fluids and tapping oils

Compatibility

Designed as an OEM-style replacement or direct tooling option for applications requiring 8-32 UNC right-hand spiral point taps in through-hole configurations.

Installation Notes

This tap should be installed by a qualified machinist or tooling technician using appropriate tap holders or floating tap heads to prevent breakage from misalignment. Always apply a compatible cutting fluid or tapping oil during use to extend tool life and improve thread finish. Ensure the workpiece is securely fixtured and the tap is aligned axially with the pilot hole before initiating the threading cycle. Do not exceed the tap's design parameters for material hardness or chip load.
