PFERD 40346 – Fiber Disc, 4-1/2″ x 7/8″, 80 Grit, VICTOGRAIN®-COOL (25pk)

PFERD 40346 – Fiber Disc, 4-1/2″ x 7/8″, 80 Grit, VICTOGRAIN®-COOL

PFERD TOOLS fibre discs are manufactured in accordance with ISO 16057 in shape A2 version F under the designation “vulcanized fibre disc”.

For maximum aggressive grinding with an extremely long tool life and an outstanding stock removal rate on steels and materials which are hard or have poor heat-conducting properties. Outstanding, constant high performance due to the VICTOGRAIN abrasive grain. Active grinding additives in the coating substantially improve the stock removal rate, prevent loading, and result in cooler grinding.

VICTOGRAIN® abrasive material is used to make some of the most effective grinding products in the world. PFERD TOOLS’ triangular, precision-formed grain achieves ultimate performance. The VICTOGRAIN® abrasive grain triangles are identical in shape and size and their cutting edges are applied to the workpiece at the optimum angle, meaning the grain needs very little energy to penetrate the workpiece. As a result, the user experiences superior productivity due to: extremely high stock removal, a long service life, and reduced heat build-up in the workpiece. Each VICTOGRAIN abrasive grain triangle is firmly fixed on one of its sides to the backing material. Due to the slim design, VICTOGRAIN offers an extremely large chip space for maximum cutting efficiency. The structure of the triangular VICTOGRAIN is specially engineered to maximize results. The very fine crystalline structure ensures optimal wear characteristics as sharp cutting edges are always exposed, with the minimum amount of abrasive breaking off from the triangle. By combining all these properties together, users benefit from optimal, consistent performance, cool grinding and an extremely long service life with uniform workpiece surface roughness.

Advantages

High productivity due to long service life and very high stock removal rate.

Consistent surface finish resulting from high-quality abrasives.

Conforms to contours due to high flexibility.

VICTOGRAIN abrasive grain allows for high productivity due to long service life, very high stock removal rate, less heat build-up in the workpiece, and a lower power output required for the power tool.

Recommendations for use

Use fibre disc in accordance with ISO 15636 with backing pad on commercially available angle grinders.

Use the appropriate grinding oil for the material to significantly increase the service life and the abrasive performance of the discs.

Ordering notes

Please order backing pad separately.

Safety notes
