The AIRCAT0.75hp Angle Disc Sander with Spindle Lock, No. 6281, features a built-in male 1/4" by 24 spindle that directly connects 2" or 3" backing pads to the tool with no additional tools required, eliminating the need for a collet and reducing the tool's profile. It has an overall height of 2.75", making it ideal for working in confined spaces, and includes built-in silencing that reduces noise levels to 79 dBa. It has a composite handle and grip with a speed control switch at the bottom of the grip.
