Balax 17586-010 Thread Forming Tap M3x0.50 Bottoming

Product Description

The BALAX 17586-010 is a thread forming tap designed for cutting M3x0.50 metric coarse internal threads in blind hole applications. Built from high-speed steel with a bright, uncoated finish, this bottoming-style tap features a 2.5-thread chamfer that allows threading close to the bottom of a blind hole. It operates in a right-hand thread direction and conforms to a 6H class of fit with a D6 thread limit. The 17586-010 is part of BALAX Series BXMOTL and is suited for use by machinists, tool and die makers, and maintenance technicians working with small-diameter metric fastener applications.

This tap is intended for blind hole threading in materials where high-speed steel tooling is appropriate. The bottoming chamfer makes it well suited for situations where thread depth must extend close to the bottom of a drilled hole. At an overall length of 1.9375 inches and a thread length of 0.625 inches, it fits standard tap handles and machine tool holders used for M3 range work. It is commonly used in precision manufacturing, repair shops, and production environments where consistent metric thread forming at small diameters is required.

Key Features

• M3x0.50 metric coarse thread size with right-hand thread direction
• Bottoming chamfer with 2.5 chamfered threads for threading close to hole bottom
• High-speed steel construction with bright, uncoated finish
• 6H class of fit, D6 thread limit for standard metric tolerance
• No coolant-through design; suitable for hand tapping and light machine tapping
• Zero oil grooves - thread forming action displaces rather than cuts material

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for M3x0.50 metric coarse blind hole threading applications in standard tap handles and machine tool setups that accept the corresponding shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with thread forming operations. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct diameter before tapping. Use an appropriate tapping fluid or cutting oil recommended for the workpiece material to extend tool life and improve thread quality. Reverse the tap periodically when hand tapping to break any chip buildup, and do not exceed the tool's rated capacity for the material being threaded.
