A compact straight grinder family for precise grinding, finishing, and controlled everyday use.
The Atlas Copco LSF29 family is built for precise grinding, sanding, and finishing where a straight tool form gives the operator better control.
With multiple speed and output variants, the series can be matched to delicate finishing work or faster material removal, depending on the application and material.
How do I choose the right LSF29 model for my line?
Step 1: Define whether the task is fine finishing, fast stock removal, or general grinding.
Step 2: Match the free speed to the material and the finish you need.
Step 3: Decide whether a Scatter damped model is preferable for operator comfort.
Step 4: Check the tool length and weight against your workspace and duty cycle.
Which model is better for precise finishing work?
For fine finishing, choose a model with a speed that gives you better control.
Faster models are generally better suited to quicker material removal.
Do all LSF29 models use the same collet size?
Yes.
All LSF29 models in this family use a 6 mm collet.
What should I check before connecting the grinder to air supply?
Make sure the air inlet matches BSP 3/8 and that your hose size is 13 mm.
That helps support stable tool supply during operation.
Are there models that can improve working comfort?
Yes.
Selected models in the family are Scatter damped, which can help reduce the feel of disturbance in the hand during extended use.
When does a higher-speed model make sense?
A higher-speed model is often a better fit when you need faster material removal or a more aggressive grinding action.
Slower models are usually better for more controlled work.
