Asada SD89249 Dies HSS 2 1/2 - 3" BSPT (AST Automatic)

Asada Corporation is a Japanese manufacturer of professional pipe and bolt threading equipment, threading dies, pressure test pumps, and pipe working machinery for plumbing, gas fitting, mechanical services, and industrial maintenance applications. Their machines and dies are engineered to produce clean, accurate threads to BSP, NPT, and metric standards, and their pressure test pumps are widely used for testing pipework integrity after installation.

Asada threading dies are precision-manufactured cutting inserts for use in Asada pipe and bolt threading machines. Available in HSS (high-speed steel) and alloy steel grades, and covering BSPT, NPT, metric, and conduit thread forms, they produce accurate threads across a wide range of pipe sizes from small-bore to 4" nominal. Dies are available in both automatic and manual machine configurations.

Where this product is used

Asada threading dies are used wherever pipe or bolt threads need to be cut in the field or workshop:

• Plumbing and mechanical services contractors cutting BSP and NPT threads on site during pipe installation.
• Industrial maintenance teams threading replacement pipe sections and hydraulic fittings.
• Gas fitting and fire protection contractors producing accurate conduit and pipe threads to specification.

Selecting the right option

Match the die to your thread form (BSPT, NPT, metric, or conduit) and the pipe size range required. HSS dies cut cleaner threads and last longer in hard materials; alloy dies are a cost-effective choice for general-purpose carbon steel pipe. Confirm compatibility with your Asada machine model before ordering — AST Automatic and B-series machines use different die sets.
