Accupro T1640323 Spiral Point Tap 10-24 3 Flutes Plug

Product Description

The ACCUPRO T1640323 is a spiral point tap designed for threading 10-24 UNC holes in metalworking applications. It drives chips forward ahead of the cut, making it well suited for through-hole tapping operations where chip evacuation is critical. Built from HSS-E Vanadium high speed steel with an oxide coating, the tap offers improved toughness and lubricity compared to standard HSS. The plug chamfer provides a gradual thread lead-in across several threads, distributing cutting forces and reducing the chance of tap breakage at entry. With a H3 thread limit and a 2/2B/3B class of fit, it produces threads compatible with standard fastener tolerances used across general machining, fabrication, and assembly work.

This tap is intended for right-hand threading of 10-24 UNC threads in through-hole setups where coolant-through is not required. It is a standard choice for machinists, maintenance technicians, and fabricators working with steel, cast iron, and similar ferrous materials in light to medium duty threading operations. The 3-flute geometry provides a balance between chip clearance and tool stability in smaller diameter applications.

Key Features

• Spiral point geometry pushes chips forward for efficient through-hole tapping
• HSS-E Vanadium steel construction for added toughness and wear resistance over standard HSS
• Oxide coating improves lubricity and reduces friction during cutting
• Plug chamfer with gradual lead-in reduces entry stress and tap breakage risk
• H3 thread limit with 2/2B/3B class of fit for standard UNC thread tolerance compliance
• Right-hand cut, no coolant-through required

Compatibility

Designed as a standard replacement spiral point tap for 10-24 UNC right-hand through-hole threading operations in general machining and fabrication environments.

Installation Notes

Spiral point taps should be installed in a rigid tapping chuck or CNC tapping head rated for the tap size. Ensure the workpiece is securely fixtured and the tap is aligned axially with the drilled hole before engagement. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Always power down or de-energize any automated equipment before manually clearing chips or changing tooling.
