EXTEC sample preparation Cut-Off Wheels are available in 6" (152 mm), 7" (178 mm), 9" (229 mm), 10" (250 mm), 12" (300 mm), 14" (350 mm), 16" (400 mm), 17" (432 mm) and 18" (455 mm) diameters and are engineered to provide the best possible burr free materials sectioning.

Aluminum Oxide (Al2O3) Abrasives are suggested for sectioning hard, medium, and soft metals, ferrous alloys, and tool steels.

Silicon Carbide (SiC) is preferred for the following: medium and soft non-ferrous metals; hard non-metallics; composites; titanium alloys and ceramics.

For best results use EXTEC Soluble Fluid, a crisp, blue-green coolant with high heat transfer properties. It is non-foaming, clean cutting and designed to discourage bacteria growth.

EXTEC PRECISION SERIES Sample Preparation Cut-Off Wheels Rubber Bonded are engineered for high speed precision sectioning. Available in 5" (127 mm), 6" (152 mm), 7" (178 mm) and 8" (203 mm) diameters in Aluminum Oxide for hard and medium-soft ferrous materials; Silicon Carbide for non-ferrous materials.
