Balax 10033-010 Thread Forming Tap 0-80 Unf Bottoming Hss

Product Description

The BALAX 10033-010 is a thread forming tap designed to cut 0-80 UNF internal threads using a cold-forming process that displaces material rather than cutting chips. Built from high-speed steel with a bright uncoated finish, this bottoming-style tap features a 1.5-thread chamfer for threading close to the bottom of a blind hole. The overall length is 1.6875 inches with a thread length of 0.3125 inches and a shank diameter of 0.1410 inches. It is suited for right-hand threading in ductile materials where chip-free thread formation is required.

This tap is used in precision machining, toolroom work, and production environments where 0-80 UNF threads are required in blind hole applications. The bottoming chamfer allows threading to near full depth in shallow or restricted holes. The BXB series designation indicates suitability for a range of ductile metals and non-ferrous alloys. No coolant-through capability is present, so external coolant or cutting oil application is standard practice during use.

Key Features

• Thread forming action displaces material with no chips, reducing the risk of chip packing in blind holes
• Bottoming chamfer with 1.5 thread lead for threading to near full blind hole depth
• High-speed steel construction for durability across a range of ductile workpiece materials
• Right-hand, 0-80 UNF thread form with Class 2B fit and H3 thread limit
• Compact geometry: 1.6875 inches overall length, 0.1410 inch shank diameter, 0.1100 inch square drive
• No oil grooves, consistent with chipless thread forming design

Compatibility

Designed for use in blind hole threading applications requiring a 0-80 UNF Class 2B internal thread in ductile metals and similar machinable materials. Verify workpiece material ductility before use, as thread forming taps are not suited for brittle or hard materials.

Installation Notes

Thread forming taps are installed by machinists and toolroom technicians using a standard tap wrench, tapping head, or CNC machine with rigid tapping capability. Ensure the tap is driven on-axis with the pilot hole to avoid thread distortion or tap breakage at this small diameter. Apply a suitable tapping fluid or cutting oil to the workpiece before and during the operation. Power off or disengage the machine spindle fully before removing or inspecting the tap.
