Hertel K008233AS Straight Flute Tap 10-24 Unc Hss

Product Description

The HERTEL K008233AS is a straight flute tap designed for cutting internal threads in a wide range of materials. Built from high-speed steel with a bright uncoated finish, this tap produces 10-24 UNC right-hand threads with a taper chamfer that eases entry and reduces the load at the start of the cut. It features 4 flutes and a thread limit of H3, making it well suited for threading applications where a Class 2B or 3B fit is required. Overall length is 2.375 inches and the tap weighs 0.25 pounds. Machinists, tool and die workers, and maintenance technicians reach for this style of tap when threading through-holes in steel, aluminum, and similar materials.

This tap is used in machine shop, MRO, and production environments where 10-24 UNC threaded holes are required. The taper chamfer style distributes cutting forces over several threads at entry, which reduces chatter and tool breakage in manual and low-speed machine tapping operations. It is appropriate for through-hole applications in both light and moderate production runs. No coolant-through feature is present, so flood or manual lubrication should be applied at the cutting zone during use.

Key Features

• 10-24 UNC thread form with right-hand thread direction
• Taper chamfer for gradual thread engagement and reduced entry force
• 4 straight flutes for chip clearance in through-hole applications
• H3 thread limit accommodates Class 2B and 3B fit tolerances
• High-speed steel construction provides wear resistance at moderate cutting speeds
• Bright uncoated finish — suitable for use with cutting fluid on a broad range of workpiece materials

Compatibility

Designed as an OEM-style straight flute tap for use in standard tap holders, T-handle tap wrenches, and compatible machine tap adapters sized for the 10-24 UNC shank profile.

Installation Notes

This tap is installed and used by machinists and maintenance technicians using manual tap wrenches or tapping heads on drill presses and lathes. Always apply an appropriate cutting fluid or tapping compound to the cutting zone before and during use. Ensure the workpiece is securely fixtured and that the tap is started square to the hole to prevent breakage. Do not exceed the speed and feed limits appropriate for high-speed steel tooling in the workpiece material being threaded.
