Oster 792ALX Industrial Pipe and Bolt Threading Machine-2" Capacity

Increase your efficiency and reduce production time with an industrial pipe and bolt threading machine. The Oster 792A “LX series” pipe and bolt threading machine is a heavy-duty, high-production bolt threading machine.

Available in 3 bed lengths, the standard bed is a workhorse for pipe threading applications and most bolt threading applications with a 7-3/4” stroke length.
For longer bolts or long runs of NPS Pipe Threads, you can re-grip on the standard-length bed, or upgrade to a long, or extra-long bed machine with a 15” or 25” stroke.
Produces Class 2A threads from ¼” to 2-1/4” Bolt and 1/8” to 2” Pipe.

Oster's commitment to quality means this threading machine is not only affordable but it is made in the USA and made to last.

Oster X1 Style Rotating Diehead for Increased Production

The Oster rotating X1 diehead allows for increased production over a standard bolt and pipe threading machine. It also creates a safer work environment because the concern over long pieces of rotating material is eliminated. It can produce up to 200 threaded ends per hour as well as cutting both right-hand and left-hand threads in a single pass.

Benefits of the Rotating X1 Diehead for High-Production Threading Machines

It’s Faster- Most threading machines rob you of production time because the operator must start and stop the spindle to insert or remove the work piece.
- With the X1 rotating diehead the need to start and stop the spindle between work pieces is eliminated.
- This allows for significantly higher production rates when compared to a conventional pipe or bolt threading machine.
It’s Safer- Shop safety is also improved when using the X1 rotating diehead machine.
- With a lathe or conventional threading machine there is always a piece of rotating material that necessitates workspace headaches, especially on longer pieces.
- With the X1 rotating diehead there is no longer a need for concern when threading long pieces of material, whether one is threading a 20” piece or a 20’ piece.
Better than a Lathe- With the X1 diehead your threads are cut in a single pass, something unmatchable with single point solutions on a lathe.
- It is superior for tackling long thread lengths and eliminates the need for live centers that add an extra machining operation.
