Baileigh ATM-27-1000 Single Arm Air Powered Tapping Machine
Are you running a fabrication or machining shop that needs a reliable air-powered tapping arm for repetitive tapping work without the fatigue that comes with handheld tools?
What if a single-arm pneumatic tapping machine gave you a 39-inch work range, 1/8-inch to 1-inch tapping capacity, six included tap holders, and table-mount stability for production tapping work?
Meet the Baileigh ATM-27-1000, a single-arm air powered tapping machine built for industrial fabrication and machining operations that need precise, repeatable tapping with reduced operator fatigue on long production runs.
With the ATM-27-1000, you get a pneumatic spindle at approximately 220 RPM, a heavy cast iron and aluminum articulated arm that neutralizes vibration and torque reaction, and a work range from 3.93 to 39.3 inches that covers a broad variety of part sizes.
When the ATM-27-1000 is mounted and set up for your job, you get accurate, consistent threads across a wide range of tap sizes with a machine that reduces the effort and fatigue of repetitive production tapping.
Baileigh ATM-27-1000 for Air-Powered Production Tapping Work
Pneumatic Spindle Delivers Consistent 220 RPM Tapping Power
The air-powered spindle delivers approximately 220 RPM for efficient tapping without the need for electrical power at the machine location. Spindle speeds range from 70 to 220 RPM, giving operators control over the tapping rate to match tap size and material conditions across the 1/8-inch to 1-inch tapping capacity range.
Articulated Arm Neutralizes Vibration and Torque Reaction
The heavy cast iron and aluminum articulated arm absorbs vibration and torque reaction during tapping, keeping operator effort low across long production runs. This ergonomic design reduces the fatigue that builds up during repetitive tapping work and maintains consistent tap alignment from hole to hole throughout the workday.
39-Inch Work Range Covers a Wide Variety of Part Sizes
The articulated arm reaches from a minimum of 3.93 inches to a maximum of 39.3 inches, covering a broad range of part sizes and positions without repositioning the machine. This work range suits the variety of fabricated parts and assemblies that production tapping operations encounter on a regular basis.
Six Included Tap Holders Cover Common Production Sizes
The ATM-27-1000 includes six tap holders sized 1/4, 3/8, 1/2, 5/8, 3/4, and 7/8 inch, covering the most common tap sizes used in industrial fabrication and machining work. The table mount system provides stable installation in workshop environments for consistent tapping performance across production runs.
