Hertel K008227AS Straight Flute Tap 10-24 Unc Hss

Product Description

The HERTEL K008227AS is a straight flute tap designed to cut internal 10-24 UNC threads in a wide range of workpiece materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread formation in production and maintenance machining environments. The taper chamfer eases entry into the hole and distributes cutting load across several leading threads, reducing torque and tool breakage risk. With four flutes and an H2 thread limit, it holds tight tolerances suitable for standard fastener fits. Overall length is 2.375 inches. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users.

This tap is suited for through-hole and open-setup tapping operations where straight flute geometry performs well in short-chipping materials such as cast iron, brass, bronze, and some plastics. The taper chamfer makes it a natural choice for hand tapping or machine tapping when starting a thread from scratch rather than continuing an interrupted thread. It is commonly used in job shops, MRO facilities, and light manufacturing where 10-24 UNC is a frequent fastener specification.

Key Features

• 10-24 UNC thread form for standard inch-series fastener compatibility
• Taper chamfer distributes cutting load and eases thread entry
• 4-flute straight flute geometry suited for short-chipping materials
• High-speed steel construction provides toughness in general-purpose tapping
• H2 thread limit maintains close tolerance for standard fits
• Bright uncoated finish — no coating buildup to affect thread dimensions

Compatibility

Designed as a general-purpose replacement or production tap for any application requiring a 10-24 UNC right-hand internal thread in short-chipping workpiece materials.

Installation Notes

A licensed machinist or qualified maintenance technician should select the correct tap drill size for 10-24 UNC before use. Ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole to prevent tap breakage. Apply appropriate cutting fluid for the workpiece material when machine tapping. Follow shop safety procedures for rotating tooling and secure the tap holder before engaging the spindle.
