Hertel K008201AS 8-32 Unc Bottoming Hand Tap Hss

Product Description

The HERTEL K008201AS is an 8-32 UNC bottoming hand tap ground to an H7 thread limit and manufactured from bright uncoated high speed steel. It is designed for cutting full threads to the bottom of blind holes in a wide range of workpiece materials. The straight 3-flute geometry provides chip clearance during hand-tapping operations and supports controlled torque application. With an overall length of 2.125 inches and a thread length of 0.75 inches, this tap is suited for shallow-depth threading work where a bottoming chamfer is required to maximize thread engagement near the base of a hole.

This tap is intended for use in machine shops, maintenance and repair operations, and production environments where 8-32 UNC threads must be cut by hand or with a tapping fixture. The bottoming chamfer, which engages only 1 to 2 thread leads before cutting full-form threads, makes it the correct choice when threading close to the bottom of a blind hole. It is typically used as the final tap in a tapping sequence following a taper or plug tap, and is installed by machinists, tool-and-die makers, and MRO technicians.

Key Features

• Bottoming chamfer for maximum thread depth in blind holes
• H7 thread limit for controlled fit and dimensional consistency
• High speed steel construction provides durability across a wide range of materials
• Bright uncoated finish suitable for general-purpose tapping applications
• 3-flute straight-flute design supports chip clearance during hand tapping
• Right-hand thread direction, 8-32 UNC thread form

Compatibility

Designed as an OEM-style bottoming hand tap for cutting 8-32 UNC right-hand internal threads in standard tapping applications where an H7 thread limit is specified.

Installation Notes

This tap is installed by machinists or MRO technicians using a standard tap wrench or tapping fixture. The workpiece should be securely fixtured and the hole properly drilled and chamfered to the correct tap-drill diameter before tapping begins. Apply appropriate cutting fluid for the workpiece material and back off periodically to break chips. Use as the final step in a tapping sequence after a taper or plug tap has established the thread lead.
