The drum rotates inside the workpiece profile, abrading material and smoothing curves in wood, plastic, metal, and similar materials. Drum sanders are essential in pattern making, guitar building, woodworking, and any application requiring the smooth finishing of tight internal radii. AIMS Industrial supplies grinding drums and drum sanding attachments for workshop and industrial use.\u003c\/p\u003e\n\n\u003ch3\u003eDrum Types and Construction\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard sanding drums:\u003c\/strong\u003e A rubber or foam core drum with a replaceable abrasive sleeve. The sleeve slips over the drum body and is held in position by tightening a central bolt that expands the rubber core. When the sleeve wears, only the sleeve is replaced — the rubber drum is reused. Available in diameters from 6mm to 76mm for most workshop drill presses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInflatable sanding drums:\u003c\/strong\u003e An inflatable rubber drum that, when pressurised, expands to grip the inside of the abrasive sleeve. The inflation pressure controls how firmly the sleeve is held and how stiffly the drum presents to the work — higher pressure produces a harder drum with more aggressive material removal; lower pressure allows the drum to conform to irregular curves.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid grinding drums:\u003c\/strong\u003e Solid abrasive-impregnated rubber or stone drums without a replaceable sleeve.

Grit selection follows the same principle as other abrasives — start with the coarsest grit that removes material at a reasonable rate and progress to finer grits for the finished surface. Common sleeve grits range from 40 (aggressive shaping) through 80, 120, and 180 to 220 (finish sanding).\u003c\/p\u003e\n\n\u003ch3\u003eSafety and Speed\u003c\/h3\u003e\n\u003cp\u003eAlways operate drum sanders at the correct speed for the drum diameter — smaller drums require higher RPM to achieve the correct surface speed; large drums at high RPM exceed the safe peripheral speed and can tear abrasive sleeves or cause the drum to fail.
