Premium cut-off wheels for metallographic sample preparation
When preparing metallographic samples, achieving a precise cut with minimal deformation and temperature effect is crucial. Using the correct cut-off wheel is essential, as it directly impacts the quality of the sample, especially for various hardness levels and material types.

Optimize cutting performance for various materials.
QPREP Premium cut-off wheels by QATM cater to a wide range of cutting needs in metallographic sample preparation. These cut-off wheels are designed to handle materials of different hardness, from 30 HV to over 700 HV, with minimal deformation and thermal load. The wheels are categorized based on the abrasive material used—aluminum oxide, silicon carbide, diamond, and cubic boron nitride (CBN) — and the bonding type—resin, rubber, or bronze. Each type offers specific advantages, such as the resin-bonded aluminum oxide wheel’s suitability for medium to very hard materials or the bronze-bonded diamond wheel’s efficiency in cutting ceramics and hard composites. Color coding enhances visual identification and quick selection. The optimized cutting properties ensure fine cutting surfaces, thereby reducing subsequent grinding steps. QATM’s premium cut-off wheels are ideal for a variety of applications, from cutting soft non-ferrous metals to hard steels, ceramics, and composites.
