Value Collection MSC-04508321 Spiral Point Tap 10-32 Unf

Product Description

The VALUE COLLECTION MSC-04508321 is a spiral point tap designed for cutting 10-32 UNF internal threads in through-hole applications. Built from high speed steel (HSS) with a bright, uncoated finish, this plug-style tap features 2 flutes and a spiral point geometry that pushes chips forward ahead of the cutting edge, reducing clogging and allowing for cleaner thread formation. The H2 thread limit provides a controlled tolerance suitable for standard 3B class of fit applications. A thread length of 0.875 inches accommodates typical fastener engagement depths in production and maintenance tapping operations. This tap is used by machinists, maintenance technicians, and production operators working in metal fabrication, general repair, and assembly environments.

This tap is suited for through-hole tapping in ferrous and non-ferrous metals where a 10-32 UNF thread form is required. The plug chamfer distributes cutting load across several leading threads, making it a practical choice for both hand tapping and machine tapping in drill press, CNC, or tapping arm setups. Its right-hand thread direction matches standard 10-32 fastener specifications. Coolant-through capability is not included, so it is best applied with external cutting fluid or tapping compound to extend tool life and improve thread quality.

Key Features

• 10-32 UNF thread form with 3B class of fit for standard tolerance internal threads
• Spiral point geometry pushes chips forward, reducing chip packing in through-hole applications
• High speed steel construction provides good wear resistance across a range of workpiece materials
• H2 thread limit for consistent fit with standard 10-32 fasteners
• Plug chamfer distributes entry cutting load across multiple threads
• Bright, uncoated finish suitable for use with cutting oils and tapping compounds

Compatibility

Designed as a standard replacement or production tap for through-hole 10-32 UNF tapping operations in manual and machine tapping applications requiring a 3B class of fit.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with tapping operations. Always secure the workpiece and ensure the tap is aligned perpendicular to the hole before beginning. Apply cutting oil or tapping compound to extend tap life and reduce the risk of tap breakage. Back the tap out periodically to clear chips when tapping by hand, and confirm spindle speed is appropriate for the material when tapping on a machine.
