A straight grinder family built for precise work in tight, direct-access areas.
Atlas Copco LSR48 is a family of pneumatic straight grinders for grinding, finishing, and material removal where a straight-line tool layout matters.
The range includes several model variants and dedicated accessories such as face spanners, rear flanges, and a closed wheel guard option on one specific version.
How do I choose the right LSR48 model?
Step 1: Define the task and the access needed at the work station.
Step 2: Choose the suitable version from the S120, S090, or S150 model families.
Step 3: Match the ordering number and the required accessories, including a wheel guard or rear flange if needed.
Is there a version with a closed wheel guard?
Yes.
Model 8,423 1,430 02 is listed with a closed wheel guard.
Which accessories are available for this family?
The listed accessories include face spanners in different sizes and rear flanges with different inner wheel diameters, depending on the version.
What is the difference between the models in the series?
The differences are the model variant and ordering number.
That lets you specify the exact grinder and matching accessories for the job.
How do I know which face spanner or rear flange I need?
Match the accessory to the model version and the required wheel or connection size.
Each accessory has its own ordering number.
What should I order together with the grinder?
It is smart to confirm whether you need a closed wheel guard, the correct face spanner, or the matching rear flange before ordering.
