The Tooltime 150mm Air Hammer (AR75-TT) is a professional-grade pneumatic tool designed for automotive technicians, garage mechanics, and serious home workshop enthusiasts who require a reliable solution for cutting, breaking, and surface preparation. It delivers a high impact rate of 4,500 BPM to handle tough metal fabrication and rust removal tasks with ease, though users should note that it requires a stable air compressor setup capable of sustaining a constant 90 PSI to achieve optimal performance.

No, the kit includes the air hammer, chisels, and the de-scaler attachment; you will need to provide your own 1/4-inch air hose and couplings.
The needle de-scaler is specifically designed for removing stubborn rust, scale, and old paint from uneven surfaces like chassis rails and engine components.
You should apply 3-5 drops of high-quality pneumatic tool oil into the air inlet at the start of every workday.
While it may operate, performance will be significantly reduced; 90 PSI is the recommended operating pressure for optimal striking force.
Yes, a coil spring chisel retainer is provided to securely hold the various chisels in place during operation.
This model features a high-speed piston design capable of 4,500 blows per minute.
Check your air compressor tank pressure and ensure your hose inner diameter is at least 3/8 inch to prevent pressure drop.
The internal O-rings may be worn or require lubrication; apply pneumatic tool oil and cycle the trigger to see if it reseals.
Verify that the coil spring chisel retainer is threaded on correctly and fully tightened against the barrel.
To set up your air hammer, connect it to your compressed air supply using a standard 1/4-inch NPT fitting. Always apply a few drops of pneumatic tool oil into the air inlet before each use to keep the internal piston lubricated. Compatibility is broad, as the tool works with standard workshop compressors that can output a consistent 4 CFM at 90 PSI. After use, wipe down the exterior with a clean cloth and store the tool in a dry place to prevent internal corrosion. Ensure the coil spring chisel retainer is securely tightened before firing the tool to prevent the chisels from ejecting unexpectedly.
