Diamax Cyclone ¾″ Small Diameter Resin Drum #1500 (SKU SRD21500)
The Diamax Cyclone ¾″ Small Diameter Resin Drum #1500 (SKU SRD21500) is a professional-grade diamond polishing tool engineered for precision wet polishing and surface refinement on natural and engineered stone surfaces. Its compact design makes it particularly effective in tight or recessed areas where larger polishing pads or wheels cannot reach, such as sink cut-outs, inside radii, corners, and intricate edge profiles.
Constructed with resin-bonded diamond abrasives, the SRD21500 combines aggressive yet controlled material removal with smooth finishing performance. The 1500-grit resin bond is ideal for mid-to-high stage polishing, smoothing out micro-imperfections, and preparing stone surfaces for higher-grit polishing steps that lead to a glossy, professional finish. Its small diameter ensures precise control, allowing operators to maintain consistent contact with detailed areas without chipping or damaging delicate edges.
Designed for wet polishing, this drum requires water cooling to protect the resin bond, reduce dust, and extend tool life. Wet operation also enhances polishing efficiency, resulting in cleaner surfaces, smoother edges, and improved overall finish quality.
The drum’s dual-thread arbor system (½″ gas and 5/8″-11) ensures compatibility with a wide range of handheld angle grinders, CNC polishing machines, and water-fed polishing tools, making it versatile for both shop and on-site applications.
Key Features
Resin-Bond Diamond Construction
Engineered with diamond abrasives embedded in a resin matrix to provide consistent polishing action and refined finishes on granite, marble, quartz, and engineered stone surfaces.
1500-Grit Finishing
Mid-to-high grit level designed to smooth surface micro-imperfections and improve surface gloss before progressing to ultra-fine grits.
Small Diameter Design
At ¾″ diameter × 1½″ length, it fits into tight or recessed areas such as sink openings, inside radii, and detailed profiles where large wheels or pads cannot reach.
Dual Thread Fitting
Built with dual thread compatibility — ½″ gas and standard 5/8″-11 — enabling use on both handheld angle grinders and CNC or water-fed polishing machines.
Wet Use Only
Designed for wet polishing to cool the drum, control dust and slurry, and extend drum life while delivering smooth, controlled polishing results.
Versatile Tool Compatibility
Fits angle grinders, water-fed polishers, and air polishers when used with the appropriate adapter or sleeve.
