Hertel K011210AS Straight Flute Tap 8-32 Unc Hss

Product Description

The HERTEL K011210AS is a straight flute plug tap designed for cutting right-hand internal threads to the 8-32 UNC standard. Manufactured from high-speed steel with a bright, uncoated finish, this tap is built for threading operations in ferrous and non-ferrous materials where coolant-through delivery is not required. With 4 flutes and an H5 thread limit, it produces consistent threads within a controlled tolerance class suitable for precision fastener applications. The overall length is 2.125 inches, with a thread length of 0.75 inches and a shank diameter of 0.168 inches. Plug chamfer geometry distributes cutting load across several leading threads, making it suitable for through-hole and blind-hole applications with adequate chip clearance.

This tap is intended for use in machine shop, maintenance, and production environments where 8-32 UNC threaded holes are required. Typical applications include tapping operations on metal workpieces in manual tap handles, tapping heads, or CNC machining centers. The straight flute design works best in shorter-chipping materials such as cast iron, brass, and some steels. It is commonly used by machinists, maintenance technicians, and tool and die professionals in both light manufacturing and general repair contexts.

Key Features

• 8-32 UNC right-hand thread standard with H5 thread limit for controlled tolerance
• 4 straight flutes for balanced cutting in short-chipping materials
• Plug chamfer distributes cutting load across entry threads, suitable for through and blind holes with clearance
• High-speed steel construction provides durability across a wide range of common workpiece materials
• Bright, uncoated finish for general-purpose use without added coating cost
• Compact 2.125-inch overall length fits standard tap holders and CNC tooling setups

Compatibility

Designed as a standard replacement or production tap for any application requiring 8-32 UNC internal threads; fits tap holders and machines accepting a 0.168-inch shank diameter with a 0.131-inch square drive.

Installation Notes

This tap should be installed and operated by a qualified machinist or maintenance technician familiar with tapping operations and cutting tool safety. Ensure the workpiece is securely fixtured and the correct tap drill size for 8-32 UNC is used prior to tapping. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use and replace if cutting edges are damaged.
