13 best pneumatic cut off tools

Pneumatic cut off tools, also known as air cut off tools, are power tools that use compressed air to drive a rotating abrasive wheel, allowing for cutting, grinding, and polishing of various materials. Here's some information about pneumatic cut off tools:

  1. Compressed Air Power: Pneumatic cut off tools are powered by compressed air, which is typically supplied through an air compressor. This makes them lightweight and easy to handle, as they don't have heavy motors or batteries.

  2. Applications: These tools are versatile and can be used for a variety of tasks, including cutting through metal, plastic, wood, and other materials. They are commonly used in metalworking, automotive repair, construction, and fabrication.

  3. Cutting Wheels: Pneumatic cut off tools use thin, abrasive cutting wheels that rotate at high speeds. These wheels come in different materials and configurations to suit specific cutting needs.For example, there are wheels designed for cutting metal, concrete, or tile.

  4. Adjustable Guard: Many pneumatic cut off tools come with an adjustable guard that helps protect the user from sparks and debris generated during cutting. It can also be adjusted to provide different cutting angles.

  5. Safety Features: Safety is a crucial aspect of using any power tool. Pneumatic cut off tools often come with safety features such as a safety lock to prevent accidental starts and a trigger lock to keep the tool running without continuous pressure on the trigger.

  6. Versatility: These tools are versatile and can often be used with various accessories, including different types of cutting wheels, grinding wheels, and sanding discs. This allows them to perform a wide range of tasks beyond cutting.

  7. Speed and Power: Pneumatic cut off tools are known for their high-speed operation, allowing for efficient material removal. The power and speed can often be adjusted to suit different materials and tasks.

  8. Portability: Because they don't rely on batteries or electrical cords, pneumatic cut off tools offer a high degree of portability. This makes them suitable for use in remote or outdoor locations where access to electrical power may be limited.

  9. Maintenance: Like all power tools, regular maintenance is important to ensure longevity and safety. This may include lubricating moving parts, checking for wear on the cutting wheel, and inspecting the air supply and hoses for leaks.

  10. Noise and Vibration: Pneumatic cut off tools can be noisy, and prolonged use may cause hand-arm vibration. It's important to wear appropriate personal protective equipment, including ear protection and gloves.

When using a pneumatic cut off tool, it's important to follow safety guidelines provided by the manufacturer and to take precautions to protect yourself and others from potential hazards. Additionally, always ensure that the air compressor is capable of providing the necessary air pressure and volume for the tool to operate effectively.

User questions & answers

Question: Where is it made
Answer: It is made of 40Cr steel
Question: Can the guard be removed
Answer: Es solamente para pistoles
Question: What is the horse power on this item
Answer: The pusher block arch is 1/2inch tall., so it can easily accommodate tall sights. Please familiarize yourself with instruction manual to properly secure the slide and set up the tool. If the sights are angled (which might be a case with some styles of suppressor height sights), it is important to match the angle of the sight with the angled side of the pusher block. Deformation mark might occur if the wrong side of the pusher is used.
Question: can this cut off wheel arbor be adapted to larger bore wheels
Answer: No. This tool was designed and intended strictly to push front and rear handgun sights. Typical red dot plates would attach to a slide with a fastener and could not be pressed.

User questions & answers

Question: What aize arbour
Answer: Take the guard off. Just wearing a face mask instead of glasses or goggles that do nothing to stop a exploding cutoff wheel. If you remove the guard and go like dipstick people do then don't blame the manufacturer when the wheel explodes and sticks unto your facell and if you don't believe it happens Google it and see the horrors. I've witnessed it before and I'll never use a grinder or cutoff wheel without a face shield
Question: does it come with a quick connect
Answer: 3” blade
Question: Can you cut metal pole
Answer: Sadzville,china
Question: can you cut concrete with it
Answer: Don't think so. The best thing to do is train your right hand to use the tool. Just practice cutting up sticks with your right hand until it is fully trained. I was unable to steer my car with my left hand one time because I am right handed. I figured if I injured my right hand I would not be able to drive, so I trained my right hand to steer and now I can steer perfectly with either hand (I seldom steer with both hands). It's true what they say, practice makes perfect because I could not control my car at all with only my left hand before.
