Every blade Coolman ships starts with the same question. What is the ground actually doing to the segment.
Most cutting tools sold in Malaysia are calibrated for European aggregate. Malaysian silica runs hotter, harder and less predictably. We built our bond formulations around that specific problem.

That sounds obvious. It is not how most of the diamond tools sold in Malaysia are built. The bulk of the market is finished blades imported from Europe, calibrated for limestone-based aggregate, low silica, predictable mineralogy. They are excellent blades. They were not designed for the ground here.
Malaysian aggregate runs above 60% silica content. The fines are sharper, the quartz inclusion is higher, and the matrix that holds a diamond cutting segment needs to release diamonds faster or the segment glazes and stops cutting.
Our bond formulations were developed over nineteen years of watching what happens to generic blades on Malaysian sites — and adjusting accordingly. We do not import a European formula and rebrand it. We manufacture to a specification that was written for this ground.
A blade that glazes on Malaysian aggregate is not a cheap blade. It is a blade that was made for a different country.
