Accupro T2644245 Spiral Flute Tap 6-32 2 Flute Hss

Product Description

The ACCUPRO T2644245 is a spiral flute tap designed for threading 6-32 (No. 6, 32 threads per inch) holes in metalworking and machining applications. Built from 3% Vanadium High Speed Steel with a bright, uncoated finish, this tap delivers reliable cutting performance without a surface treatment that could affect thread tolerance. The modified bottoming chamfer allows threading close to the bottom of a blind hole. At 2.0 inches overall length, it carries a right-hand thread and right-hand flute direction with a 40-degree helix angle suited for chip evacuation in aluminum and similar materials. The H5 thread limit ensures consistent tolerance control for close-fit thread applications.

This tap is intended for use in machine shops, maintenance facilities, and production environments where 6-32 internal threads are required. The spiral flute design promotes upward chip evacuation, making it well suited for blind-hole tapping in aluminum. It is typically run in CNC machining centers, tapping heads, or manual drill presses with appropriate tapping fluid. The 2-flute configuration and fast flute style reduce cutting resistance in softer, non-ferrous materials.

Key Features

• Modified bottoming chamfer for threading close to the bottom of blind holes
• 40-degree helix angle promotes efficient chip removal in aluminum
• H5 thread limit for controlled tolerance in close-fit assemblies
• 3% Vanadium HSS construction for wear resistance and edge retention
• Bright, uncoated finish — no coating variables affecting thread dimensions
• Right-hand thread and right-hand flute, 2-flute configuration

Compatibility

Designed as a direct-fit spiral flute tap for 6-32 threaded hole applications in aluminum and compatible non-ferrous materials.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly aligned tapping fixture, CNC spindle, or drill press with a tapping attachment. Always apply appropriate cutting fluid or tapping compound before use and ensure the workpiece is securely clamped. Confirm spindle speed and feed rate are appropriate for the material and tap diameter before engaging the cut. Inspect the tap for wear or damage before each use to avoid thread failure or breakage.
