FAQs

What size rotary bits can I use with this grinder?

The grinder comes fitted with a 1/8" collet, suitable for standard 1/8" shank rotary bits. Other collet sizes can be fitted, but they are not supplied with the kit.

How much air pressure and flow does this tool require?

The tool operates at a working pressure of 90 PSI and has an air consumption of 4 CFM. Ensure your air compressor can meet these requirements.

How often should I lubricate the tool?

It is recommended to add a few drops of air tool oil before each use and periodically during extended operation. Check and refill the inline oiler as needed.

What is included in the 15-piece kit?

The kit includes the Air Micro Grinder with hose, an inline oiler, 10 assorted grinding stones, 2 adjusting keys, an oil bottle, a quick-release fitting, and a blow-molded storage case.

Can I use this for heavy-duty grinding tasks?

This micro die grinder is designed for precision and detail work, such as craft, etching, and engraving. It is not intended for heavy-duty grinding applications.

How do I adjust the speed?

The grinder features a built-in speed regulator. You can adjust the rotation speed by turning this regulator to achieve precise control for your specific task.

Troubleshooting

Grinder not starting or running slowly

Check air pressure from the compressor. Ensure the air line is securely connected and not kinked. Verify the tool is adequately lubricated. Check the speed regulator is not fully closed. Ensure the collet is not overtightened, preventing the spindle from turning.

Excessive vibration

Ensure the rotary bit is securely and correctly seated in the collet. Check that the bit itself is not bent or damaged. Make sure the collet is tightened properly.

Air leaking from the tool body

Inspect all connections for tightness. Check the O-rings and seals for wear or damage. If leakage persists, the tool may require professional servicing.

Poor performance or cutting ability

Confirm that the air compressor is meeting the required 4 CFM at 90 PSI. Ensure the tool is properly lubricated. The grinding bits may be worn and require replacement.

Pros and Cons

Pros

  • Extremely compact for detailed and intricate work.
  • High maximum RPM (54,000) for efficient material removal.
  • Variable speed control allows for precise operation.
  • Rear exhaust system improves user comfort and workspace cleanliness.
  • Comes with a good selection of essential accessories in a convenient case.

Cons

  • Requires an air compressor, adding to the overall setup cost and complexity.
  • Air consumption of 4CFM may require a more powerful compressor for sustained use.
  • Only includes a 1/8" collet; users needing other bit sizes must purchase them separately.
  • The 1.5m hose might be limiting for some larger workspaces.
  • Rear exhaust placement, while helpful, could still be a consideration in very confined areas.

Setup, Compatibility & Care

Setup:

  1. Ensure your air compressor is rated for at least 90 PSI and can supply 4 CFM of air flow.
  2. Connect the quick-release fitting to your air hose.
  3. Attach the quick-release fitting to the grinder's inlet port or directly to the 1/4" BSP thread if not using the quick release.
  4. Attach your desired 1/8" rotary bit into the collet and tighten securely using the provided adjusting keys.
  5. Connect the grinder to the air supply.
  6. Add a few drops of specialized air tool oil into the inline oiler or directly into the air inlet before first use and periodically during operation.
  7. Turn on the air compressor and adjust the built-in regulator to achieve the desired working pressure (typically 90 PSI).

Compatibility:

  • Air Source: Requires an air compressor capable of delivering 4 CFM at 90 PSI.
  • Fittings: Features a standard 1/4" BSP thread for air line connection. Compatible with standard air compressors and hoses.
  • Rotary Bits: Primarily designed for 1/8" shank rotary bits due to the fitted collet. Other collet sizes can be fitted but are not included.

Care:

  • Lubrication: Regularly use air tool oil. Add oil before each use and at regular intervals during extended operation. Check the inline oiler and refill as needed.
  • Cleaning: After each use, disconnect from air and wipe down the tool with a clean, dry cloth. Ensure the exhaust port is free of debris.
  • Storage: Store the grinder and all accessories in the provided blow-molded case to protect them from dust and damage.
  • Bit Changes: Always disconnect the air supply before changing bits. Ensure the collet is clean and free of debris.
