Hertel K008246AS Spiral Point Tap 10-24 Unc Bottoming Hss

Product Description

The HERTEL K008246AS is a spiral point tap designed to cut 10-24 UNC threads in through-hole and bottoming applications. It is manufactured from high-speed steel and carries a bright, uncoated finish. With 2 flutes and an H3 thread limit, this tap produces 2B/3B class-of-fit threads with consistent dimensional accuracy. The right-hand spiral point geometry pushes chips forward ahead of the cutting action, reducing chip packing in the flute. A 7/8-inch thread length provides adequate engagement depth for standard production and repair threading work. Machinists, tool-and-die makers, and maintenance technicians install this tap in drill presses, CNC machining centers, and hand-tapping fixtures.

This tap is suited for threading 10-24 UNC holes in ferrous and non-ferrous materials across general manufacturing, MRO, and production environments. It is appropriate for both light production runs and single-piece repair work where a standard 2B or 3B fit is required. The bottoming chamfer allows threading to the bottom of a blind hole when that capability is needed. No coolant-through capability is present, so conventional flood or brush-applied cutting fluid is used during operation.

Key Features

• 10-24 UNC thread form with H3 thread limit for 2B/3B class-of-fit tolerance
• Spiral point geometry advances chips forward, reducing clogging in through-hole applications
• Bottoming chamfer allows threading close to the bottom of a blind hole
• High-speed steel construction provides hardness and wear resistance for general-purpose threading
• Bright, uncoated finish suitable for use with standard cutting fluids
• Right-hand thread direction, 2-flute design for standard tapping operations

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring a 10-24 UNC bottoming spiral point tap with an H3 thread limit and 2B/3B class of fit.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, drill press, or CNC tapping head. Ensure the workpiece is securely fixtured and that the pilot hole is drilled to the correct tap drill diameter for 10-24 UNC before beginning the threading operation. Apply an appropriate cutting fluid for the workpiece material to extend tool life and produce a cleaner thread. Never force a tap against resistance — back off periodically to break chips and prevent tap breakage.
