Balax 01102-010 Thread Forming Tap M1x0.25 Bottoming Hss

Product Description

The BALAX 01102-010 is a thread forming tap designed for M1x0.25 metric coarse threads in blind hole applications. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap features a bottoming chamfer of 2.5 thread pitches, allowing threads to be formed close to the bottom of a blind hole. Manufactured from high-speed steel with a bright uncoated finish, it is suited for use in ductile metals and soft alloys. The thread limit is H2, indicating a close tolerance fit. Overall length is 1.625 inches with a thread length of 0.25 inches.

This tap is used in precision machining and assembly applications where M1x0.25 metric coarse internal threads are required in blind holes. The bottoming chamfer makes it appropriate as a finishing tap after a plug or taper tap has started the thread. Typical installation environments include tool and die shops, instrument manufacturing, electronics assembly, and other work involving fine metric fasteners. It is part of the BXMIN series and is intended for use in manual tapping or light machine tapping setups.

Key Features

• Thread forming design displaces material for chip-free, stronger threads
• Bottoming chamfer (2.5P) for threading close to the bottom of blind holes
• High-speed steel construction for durability across a range of ductile workpiece materials
• H2 thread limit for close-tolerance metric thread production
• Right-hand thread direction, M1x0.25 metric coarse pitch
• No coolant-through feature; suited for standard tapping fluid application

Compatibility

Designed for blind hole threading of M1x0.25 metric coarse internal threads in ductile metals and soft alloys where a bottoming thread form is required.

Installation Notes

Thread forming taps should be installed and operated by a machinist or tooling technician familiar with tapping procedures and proper speeds for the workpiece material. Ensure the correct drill size for thread forming is used, as it differs from the drill size required for cutting taps. Apply appropriate tapping fluid or cutting oil before and during the operation. Never force the tap if resistance increases unexpectedly, as breakage in small-diameter taps is difficult to recover from.
