Balax 12023-010 Extension Thread Forming Tap 10-24 H3 Hss

Product Description

The BALAX 12023-010 is a thread forming extension tap designed for cutting 10-24 UNC internal threads in applications where standard-length taps cannot reach. Built from high-speed steel with a bright, uncoated finish, this tap cold-forms threads rather than cutting chips, producing stronger threads with a better surface finish in ductile materials. The bottoming chamfer allows threading close to the bottom of a blind hole. At 4 inches overall length with a 7/8-inch thread length, the extended reach makes it suitable for deep-cavity or recessed hole applications that standard taps cannot access.

This tap is used in machining and fabrication environments where threaded holes must be formed in recessed, deep, or hard-to-reach locations. The thread forming design suits ductile metals and plastics where chip removal is difficult or undesirable. The H3 thread limit indicates a tighter tolerance class, making this tap appropriate for precision threading work requiring consistent 2B and 3B class-of-fit results. Machinists, tool and die makers, and maintenance technicians working on production or repair applications will find this tap appropriate for both manual and machine tapping setups.

Key Features

• Thread forming design produces stronger threads and eliminates chip removal in ductile materials
• Bottoming chamfer allows threading close to the bottom of blind holes
• 4-inch overall length provides extended reach for deep or recessed cavities
• H3 thread limit for consistent precision across 2B and 3B class-of-fit applications
• High-speed steel construction for durability in production and maintenance tapping
• Right-hand flute direction, compatible with standard tapping equipment

Compatibility

Designed as an OEM-style replacement and standard tooling option for 10-24 UNC thread forming applications requiring extended reach in manual or CNC tapping setups.

Installation Notes

Thread forming taps require proper lubrication and are intended for use in ductile materials only - do not use in cast iron, hardened steel, or other brittle materials. Secure the workpiece before tapping and use a calibrated torque-controlled tapping arm or CNC tapping head where possible to avoid tap breakage. Inspect the tap for wear or damage before each use. Follow applicable shop safety standards and ensure the spindle speed is appropriate for the material and tap diameter.
