Hertel K008243AS25 Spiral Point Tap 10-24 Unc Hss Tin

Product Description

The HERTEL K008243AS25 is a spiral point tap designed for cutting internal threads in through-hole applications. It features a plug chamfer style, 2-flute geometry, and is manufactured from high-speed steel with a titanium nitride (TiN) coating. The TiN coating increases surface hardness and reduces friction, extending tool life in production environments. Thread size is 10-24 UNC with a right-hand thread direction and an H2 thread limit, providing close tolerance control for standard fastener fits. The shank diameter is 0.194 inches. This tap is intended for machinists and maintenance professionals working in machine shops, fabrication facilities, or field repair settings.

The K008243AS25 is suited for threading through-holes in steel, aluminum, and similar machinable materials at the 10-24 UNC standard. The spiral point geometry pushes chips ahead of the cutting flutes rather than packing them into the flute gullets, making it effective in through-hole drilling operations on CNC machines, manual mills, and drill presses. The 7/8 inch thread length supports standard thread engagement depths for 10-24 fastener applications in light-duty and general-purpose assemblies.

Key Features

• 10-24 UNC right-hand thread form with H2 thread limit for close tolerance fitment
• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• High-speed steel construction provides toughness across a range of machinable materials
• TiN coating improves wear resistance and reduces cutting friction
• Thread length of 7/8 inches with a shank diameter of 0.194 inches
• No coolant-through feature; suitable for conventional flood or manual lubrication

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for standard 10-24 UNC through-hole threading applications in general machining and maintenance repair operations.

Installation Notes

This tap is installed by machinists using a standard tap wrench, tapping head, or CNC rigid tapping cycle. Always use appropriate cutting fluid or tapping compound to protect the cutting edges and improve thread quality. Secure the workpiece firmly before tapping to prevent movement during the threading operation. Follow shop safety practices and ensure the tap is properly aligned to the drilled hole centerline to avoid tap breakage.
