The review

Finding tools that work effectively for a certain job can save technicians time and frustration. The reviewer found that the SP Air Flex Head Cut-Off Tool was a well-made tool but it won’t fit every technician’s needs.

Brian Noel, an automotive professor at Cosumnes River College in Sacramento, Calif., likes that the tool has a metal shield rather than a plastic one, so it will not be destroyed over time by sparks. He also appreciated the built-in regulator and adjustable exhaust.

“While the tool itself is bulkier than many cut-off tools, the flex head allows it to pivot in different positions, which can increase its maneuverability and utility in some situations,” he says.

Noel and his students used the SP Air Flex Head Cut-off Tool primarily in a classroom setting for cutting sheet metal, metal brackets and general fabrication. For that application, this cut-off tool was bulkier than other options, and the flexible head wasn’t necessary.

“I could see this tool being very appealing to someone in the collision repair/custom fabrication side of the industry, as it would likely make long cuts in body panels much easier to achieve without awkward positioning of the user’s body or hands,” Noel says.

Noel found that the tool operated similarly to other cut-off tools in most situations. Using the flex-head feature was as easy as sliding the collar and pivoting the head accordingly.

The tool did require some setup. Like any air tool, the Flex Head Cut-off Tool needed a quick disconnect fitting installed. A cutting wheel also needed to be installed along with the included shield. Noel adds that, if desired, a built-in regulator can be added to adjust the speed and power output of the tool.

The cut-off tool and shield were boxed along with wrenches to hold the mandrel while installing the cutoff wheel. There was also a one-page brochure about the tool and a generic booklet of precautions applicable to all air/pneumatic tools.

As an improvement, Noel notes that ideally, the tool would have the flex-head and still be able to maintain the slimmer size of other cut-off tools.

“The flex head feature is nice, but is probably overkill for most users outside of collision/custom fabrication areas of the industry,” Noel says. “For most general technicians that need to do occasional cutting, the added bulk of the tool probably offsets the versatility of the flex head.”

Overall, Noel found that the tool was well made and designed, and could work in a variety of applications.
