The Hybrid disc is made from the following components.
Premium Ceramic Abrasive Grain - self-sharpening ceramic particles that deliver fast cutting, long life, and consistent grinding performance.
High-Strength Resin Bonding System - heat-resistant resin securely bonds the abrasive grains and withstands demanding grinding applications.
Reinforced Fibreglass Backing provides strength, stability, and safety during high-speed operation.
Semi-Flexible Hybrid Construction - combines the aggressive stock removal of a grinding wheel with the smoother finish and control of a flap disc, while reducing vibration.
The Josco Hybrid Grinding Disc is designed to be used on:
Stainless Steel (INOX) -ideal for grinding welds, blending joins, and finishing stainless steel fabrications.
Mild Steel - suitable for weld removal, edge grinding, deburring, and general fabrication work.
Carbon Steel / Structural Steel - fast stock removal and surface preparation in construction and engineering applications.
Iron - effective for grinding cast iron and other ferrous metal components.
The ceramic hybrid design provides faster grinding than a flap disc, a flatter finish, and less vibration, making it suitable for both heavy stock removal and finishing on stainless steel, steel, and iron.
The Josco JR21901 Hybrid Ceramic Grinding Disc is a premium performance abrasive designed for professionals who demand fast results and maximum productivity. Engineered with advanced hybrid ceramic grain technology, this disc delivers exceptionally aggressive cutting action, making it ideal for weld removal, beveling, edge preparation, rust removal, and heavy stock removal across a wide range of metals.
A key advantage of the JR21901 is its rapid material removal rate. The ceramic abrasive grain continually fractures during use, exposing fresh cutting edges that maintain a sharp, aggressive grind throughout the life of the disc. This allows users to complete jobs faster while applying less pressure, reducing operator fatigue and improving overall efficiency.
