The 4 x 36 Inch Bench Sander Can Do The Following

  • Basic Techniques:

    • Deburring: With its powerful motor, this tool thoroughly removes sharp edges and burrs from cut or machined metal pieces, ensuring both safety and a smooth surface ready for further finishing.
    • Surface Conditioning: Creating a uniform finish and great results on metals, prepping for further polishing or application of coatings. This can range from a rougher finish for adhesion to a finer, pre-polish condition.

    Specialized Techniques:

    • Flat sanding: Using the work rest on the front of the S4SWB allows for accurate sanding of flat surfaces, ensuring great results when squaring up stock or creating accurate angles.
    • Chamfering/Beveling: Using angled rests or guides, the S4SWB can create chamfers (sloped edges) and bevels on metal for aesthetic or functional purposes.
    • Polishing: While technically a different process, using very fine polishing belts allows the S4SWB to achieve great results, highly-reflective finishes on metals with the help of polishing compounds.
