Thick Cutting and Grinding Discs for Metals

Specifications

• disc shape: flat No.41, concave No.42, 27 (profile No.41, 42, 27);
• abrasive material: aluminium oxide (A), silicon carbide (C);
• abrasive material grain size: 24, 30, 36, 60;
• binding material: bakelite;
• hardness: R- and Q-grade;
• peripheral speed: 80 m/sec.

Advantages

• these discs are the most universal types for a wide range of applications (carbon and highspeed steels, various alloys, forge iron and so on);

• high performance and a slower wear-out of disc due to its optimum preset hardness value;
• minimal vibration;
• fast high-quality cutting;
• a neat cutting line without any burrs or irregularities;
• ensures best time and effort saving for an operator when cutting with this disc;
• meets high safety and quality requirements for cutting discs of the EN and DSA standards;
• the discs are produced with high-quality raw materials.

Recommendations for operation:
• these discs are designed for vertical cutting only;
• they suffer from side loads, that's why they must not be used for grinding of even the smallest irregularities;
• when cutting avoid bringing the cutting disc to a workpiece from the side most susceptible to vibration;
• in stone-treatment works we recommend using a vacuum cleaner.

Application

• grinding of parts and structures made of various steel grades;

• to be used with manual angle grinders

Recommendations for operation

• Special care and attention are obligatory, because in case a small crack appears on an abrasive disc, the latter tends to break into pieces at high rotation rate;
• Never fit a large diameter cutting disc onto a smaller size angle grinder, because small angle grinders have a higher spindle rotation rate. As a result, the disc speed (when touching the material) exceeds the admissible value - hence, a load on the disc increases drastically;
• Operating a machine without its safety guard in place is strictly prohibited;
• A cutting disc must rotate freely, touching neither the safety guard nor the body of the angle grinder.
