Description
The OSG BA A-Spiral Point Threading Tap is a precision tool designed to cut British Association (BA) threads in through-holes with clean, accurate results. It’s built for machinists and technicians who demand dependable performance in compact, small-diameter applications.
- Thread Type: BA (British Association) with A-Spiral Point geometry to push chips forward and prevent clogging in through-holes
- Material: Powder metal body delivering hardness, wear resistance, and good heat tolerance for demanding tapping tasks
- Coating: TiCN coating extends tool life and improves cutting efficiency at higher speeds
- Size and Orientation: 4BA, right-hand thread, optimized for precise, small-diameter fasteners
- Chip Evacuation: Spiral point design actively directs chips away from the cutting zone to reduce downtime
- Application: Specifically engineered for tapping BA threads in through-holes across a range of materials
- Performance: Suitable for high-speed threading while maintaining consistent thread quality and extended tool life
With its combination of spiral-point geometry, durable powder-metal construction, and the TiCN coating, this tap delivers reliable, long-lasting performance in precision BA threading tasks. The design minimizes chip buildup, supports faster cycles, and helps maintain accurate thread depth and finish, making it a dependable choice for small-component assemblies, instrumentation housings, and other delicate mechanical applications that require 4BA threads.
