Ten-pack rotary blades for fabric and leather

The Olfa RB45-10 supplies ten 45 mm straight-edge rotary blades made from tungsten. Each blade is .3 mm thick and fits compatible Olfa rotary cutters used for fabric, leather, paper, tarp, upholstery and vinyl. A built-in dispenser keeps the pack organised and protects the cutting edges until they are needed.

Check cutter model before ordering

Verify that your rotary cutter accepts 45 mm round blades and matches the RTY-2 series or the listed Grainger part numbers. The blades are designed for straight cutting only and will not fit cutters that require a different diameter, thickness or mounting style. Confirm compatibility to avoid a mismatch.

Tungsten steel holds an edge through heavy materials

Tungsten construction resists dulling when slicing through dense upholstery or layered tarp. The straight edge produces clean cuts without fraying on woven fabrics or vinyl. The dispenser lets you swap blades quickly during long projects while keeping the unused blades safely covered.
