Balax 11645-000 Thread Forming Tap 8-32 Unc Plug Hss

Product Description

The BALAX 11645-000 is a thread forming tap designed for cutting 8-32 UNC internal threads in through-hole applications. Built from high-speed steel with a bright uncoated finish, this plug-style tap features a 4-thread chamfer that allows controlled entry into the workpiece. It carries an H5 thread limit and a 2B class of fit, making it suitable for standard fastener thread tolerances in production and maintenance environments. With an overall length of 2.125 inches and a tapping depth of 0.75 inches, this tap is sized for compact threading tasks. Machinists, toolroom technicians, and maintenance mechanics are the primary users.

The BALAX 11645-000 is applied in through-hole threading operations where an 8-32 UNC thread form is required. The plug chamfer makes it well suited for threading operations that begin in a pre-drilled through hole. The BXP series designation indicates it is optimized for forming threads without cutting, displacing material rather than removing chips. This makes it a common choice in ferrous and non-ferrous materials where chip control is a concern. It is used in both manual tapping and machine tapping setups in light manufacturing and field repair contexts.

Key Features

• Thread forming design displaces material instead of cutting, reducing chip generation
• Plug chamfer with 4 chamfered threads for controlled thread entry
• High-speed steel construction for durability across a range of workpiece materials
• H5 thread limit with 2B class of fit for standard fastener thread tolerances
• Right-hand thread direction, 1 oil groove for lubrication during forming
• BXP series - designed for through-hole thread forming applications

Compatibility

Designed for through-hole threading applications requiring an 8-32 UNC thread form with a 2B class of fit. Suitable for use in materials compatible with thread forming rather than thread cutting.

Installation Notes

Thread forming taps should be installed and operated by qualified machinists or maintenance mechanics familiar with proper tap drill sizing for forming operations, which differs from cutting tap drill charts. Always apply appropriate tapping fluid or cutting oil before and during the tapping operation. Secure the workpiece firmly before tapping to prevent movement. Do not force the tap if resistance increases unexpectedly - back off and clear the hole before continuing.
