Oil country lathe 3A-38

Key Advantages of the Myday 3A-38 Pipe Threading Lathe

1. Wide Range of Processable Pipe Diameters

   • Processes pipes from ½ inch (15 mm) to 2 inches (50 mm) in standard configuration

   • Capable of cutting both inch threads (standard plumbing threads: 1/2", 3/4", 1", 1¼", 1½", 2") and metric threads

   • Quick die change enabled by a modular mounting system requiring no additional tools

2. High Productivity in Field Conditions

   • High-speed threading of a complete thread on a single pipe

   • Powerful electric motor ensures stable operation even when machining thick-walled pipes

   • Continuous operation throughout a full shift without overheating, thanks to an efficient ventilation system

3. Ease of Operation Without Special Training

   • Intuitive control system with clearly marked clamping and feed levers

   • Automatic die feed activated by handle rotation—no complex depth-of-cut adjustments required

   • Minimal number of serviceable components—machine ready for operation immediately after unpacking and die installation

4. Reliable Pipe Clamping System

   • Three-jaw self-centering chuck provides secure pipe fixation without backlash or rotation under load

   • Adjustable clamping force prevents deformation of thin-walled pipes during machining

   • Compatible with pipes made of carbon steel, galvanized steel, and stainless steel
