Value Collection MSC-04609632 Spiral Flute Tap 6-32 Unc

Product Description

The VALUE COLLECTION MSC-04609632 is a spiral flute tap designed for cutting internal threads in ferrous and non-ferrous materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap produces 6-32 UNC threads to a 2B class of fit with an H3 thread limit. The modified bottoming chamfer allows threading close to the bottom of a blind hole. With a 45-degree helix angle and a fast flute style, it efficiently evacuates chips upward during cutting, reducing the risk of chip packing in shallow or moderately deep holes. Overall length is 2 inches. This tap is suited for machine shops, maintenance operations, and production environments where consistent thread quality is required.

This tap is intended for right-hand, right-hand-flute threading applications in typical machine tapping setups. The 6-32 UNC size is commonly used in light fastener applications across electronics, instrument panels, and sheet metal assemblies. It is compatible with standard tap holders and tapping heads configured for small-diameter machine taps. The modified bottoming chamfer makes it a practical choice when thread engagement must start near the base of a blind hole without a full bottoming tap transition.

Key Features

• 6-32 UNC thread form with 2B class of fit and H3 thread limit for reliable thread tolerance
• Modified bottoming chamfer for threading close to the bottom of blind holes
• 45-degree helix angle with fast flute style for efficient upward chip evacuation
• High-speed steel construction provides durability across a range of workpiece materials
• Bright, uncoated finish — no coating variables affecting thread dimensions
• Right-hand thread and right-hand flute direction for standard machine tapping

Compatibility

Designed as an OEM-style replacement or standard tooling option for machine tapping operations requiring 6-32 UNC internal threads with a modified bottoming chamfer profile.

Installation Notes

This tap is installed by machinists or tool and die professionals using a standard tap holder, tapping head, or CNC tapping cycle configured for the appropriate spindle speed and feed rate for the workpiece material. Always ensure the workpiece is securely fixtured and the tap is properly aligned to the pilot hole before engaging the cut. Use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish. Do not reverse the tap under power without a reversible tapping attachment capable of handling the tool diameter.
