Balax 12003-010 Thread Forming Tap 10-24 Unc Bottoming

Product Description

The BALAX 12003-010 is a bottoming-chamfer thread forming tap designed for blind hole threading in 10-24 UNC applications. Built from high-speed steel with a bright uncoated finish, this tap cold-forms threads by displacing material rather than cutting it, producing stronger threads with no chips to clear. It carries a H3 thread limit and is part of the BXOTL series. With an overall length of 2.375 inches and a thread length of 0.6 inches, it fits standard tapping chucks used in production and maintenance machining environments. Installation is performed by machinists and toolroom professionals working with ferrous and non-ferrous materials in blind hole setups.

This tap is suited for blind hole threading operations in production machining, maintenance, and repair applications where chip-free thread forming is required. The bottoming chamfer with 1.5 thread lead allows threading close to the bottom of blind holes, making it appropriate for tight-tolerance assemblies. The BXOTL series is designed for use in materials that are compatible with cold-forming processes, including mild steels, stainless, aluminum, and similar ductile materials.

Key Features

• Bottoming chamfer with 1.5P lead for threading close to the base of blind holes
• Thread forming design eliminates chips, reducing tap breakage risk and improving thread strength
• H3 thread limit for consistent tolerance control in 10-24 UNC threads
• High-speed steel construction for durability in production tapping operations
• Single oil groove aids lubricant distribution during the forming process
• Right-hand thread direction, standard for 10-24 UNC applications

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for blind hole 10-24 UNC threading operations in standard tapping chucks and tap holders.

Installation Notes

Thread forming taps require a properly sized forming tap drill hole, which is larger than a cutting tap drill - consult a thread forming drill chart for the correct diameter before use. Apply cutting or tapping fluid rated for the workpiece material to reduce forming torque and extend tap life. Secure the workpiece and ensure the tap is aligned perpendicular to the hole before engagement. This tap is intended for use by trained machinists familiar with thread forming processes and appropriate machine feeds and speeds.
