Balax 12223-010 Thread Forming Tap 10-32 Unf Bottoming

Product Description

The BALAX 12223-010 is a thread forming tap in the BXOTL series, designed for cutting 10-32 UNF internal threads in blind hole applications. Unlike cutting taps, thread forming taps displace material rather than remove it, producing stronger threads with no chips to clear. This tap is manufactured from high-speed steel with a bright uncoated finish and carries a bottoming chamfer with 1.5 thread pitches of lead. It is sized for Class 3B fit at H3 thread limit, making it appropriate for close-tolerance fastener applications in precision assemblies. Machinists, tool and die makers, and maintenance technicians working with 10-32 threaded components are the primary installers.

This tap is intended for blind hole threading in materials that form rather than cut cleanly, such as soft steels, aluminum, and similar ductile metals. The bottoming chamfer allows threading to the bottom of a blind hole with minimal unthreaded depth. The BXOTL series designation indicates a roll-form geometry suited for CNC tapping centers and manual tapping operations where chip contamination is a concern. One oil groove aids lubrication during the forming process. This tap is appropriate for light manufacturing, maintenance and repair operations, and precision fabrication environments.

Key Features

• Thread forming design displaces material for chip-free blind hole threading
• Bottoming chamfer with 1.5P lead for threading close to the bottom of blind holes
• 10-32 UNF thread form, Class 3B fit, H3 thread limit for close-tolerance work
• High-speed steel construction with bright uncoated finish
• Single oil groove for lubrication assist during forming
• Right-hand thread direction, BXOTL series geometry

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for 10-32 UNF blind hole applications requiring a Class 3B fit and H3 thread limit.

Installation Notes

Thread forming taps require the correct tap drill size for the material being tapped - undersizing or oversizing the pilot hole will affect thread fit and tool life. Use a suitable tapping fluid or cutting oil compatible with the workpiece material before driving the tap. Secure the workpiece and ensure the tap is driven in true alignment with the hole axis to avoid tap breakage. This tap should be installed or replaced by a qualified machinist or maintenance technician following standard shop safety practices.
