Quick answer
Choose abrasive bands for drum sanders by matching the band size to your drum diameter, selecting the right grit for your material, and ensuring the shank fits your tool. Start with a medium grit like 80 for general-purpose sanding.
Why band size and shank matter
Abrasive bands must match the drum's diameter and width exactly. A loose band slips, while an overly tight one can tear. The shank diameter must also fit your rotary tool or drill chuck — common sizes are 1/8 inch and 1/4 inch. Using the wrong shank can damage the tool or cause unsafe operation.
Grit selection by material
Coarse grits (40–60) remove material fast on wood or soft metals. Medium grits (80–120) are ideal for smoothing and light shaping. Fine grits (150+) polish and finish. For most DIY projects, 80 grit is a versatile starting point.
Steps to choose abrasive bands for drum sanders
- Measure your drum diameter and width: Check the drum's diameter and width in inches. The band's inner diameter should match the drum exactly. A 1/2" x 1/2" band fits a 1/2" diameter drum that is 1/2" wide. Common mistake: guessing the size. Always measure with a caliper or ruler.
- Select the correct shank size: Verify your tool's chuck capacity. Most rotary tools accept 1/8" or 1/4" shanks. The included drums in the Supergrit kit have a 1/8" shank, which fits standard Dremel-type tools. A shank that is too large won't fit; one that is too small may wobble.
- Choose the right grit for your task: For removing paint or rough edges, pick 60 grit. For general sanding on wood or plastic, 80 grit works well. For finishing before painting, use 120 grit or finer. Checkpoint: test on a scrap piece first to confirm the grit removes material at the desired rate.
- Inspect band quality and quantity: Look for bands made from aluminum oxide (AO) for durability on wood and metal. Kits with multiple bands, like the 100-band Supergrit set, reduce downtime from band changes. Cheap bands may shed grit quickly; AO bands last longer and cut consistently.
