Accupro T2670362B Spiral Point Tap 12-24 2 Flutes Plug

Product Description

The ACCUPRO T2670362B is a spiral point plug tap designed for cutting 12-24 unified coarse threads in through-hole applications. Built from 3% vanadium high speed steel with a bright finish, it delivers consistent thread form and durability in production and maintenance environments. The spiral point geometry pushes chips ahead of the tap and out of the hole, preventing chip packing in through-hole operations. With a 2B class of fit, it produces threads compatible with standard 2A fasteners. This tap is sized at 2.375 inches overall length with a 17 mm thread length, making it suitable for typical machine screw threading work in light to medium materials.

The T2670362B is suited for threading aluminum and similar non-ferrous and light ferrous materials in through-hole configurations. Its plug chamfer provides a gradual lead-in, making it well suited for CNC machining centers, drill presses, and manual tapping operations in job shop, production, and MRO settings. The right-hand thread direction is standard for the vast majority of fastener applications. Machinists, maintenance technicians, and toolroom operators are the primary users of this tap size and style.

Key Features

• Spiral point geometry pushes chips forward through the hole, reducing tap breakage risk in through-hole threading
• 3% vanadium high speed steel construction provides improved wear resistance over standard HSS
• Plug chamfer with gradual lead-in eases starting and reduces torque demand
• 2B class of fit produces threads compatible with standard 2A machine screws and fasteners
• Bright finish with no coating — suitable for use with cutting oils and water-soluble coolants
• Right-hand thread direction, no coolant-through requirement simplifies setup

Compatibility

Designed as a standard replacement or production tap for 12-24 unified coarse through-hole threading applications, particularly in aluminum and similar machinable materials.

Installation Notes

Spiral point taps are intended for through-hole threading only — do not use in blind holes where chip ejection is blocked. Secure the workpiece and use a tapping fluid or cutting oil appropriate for the base material before starting. Ensure the tap is properly aligned with the hole axis to prevent tap breakage and thread distortion. Operators should follow applicable shop safety practices when using rotating tooling on machine tools.
