45 mm Rotary Blade Pack

This pack contains five straight-edge rotary blades designed for Olfa RTY-2 series cutters. Each blade measures 45 mm in diameter and is ground from tungsten carbide tool steel. The blades ship inside a protective dispenser for safe storage and quick changes. They are intended for crafters and professionals who cut fabric, leather, paper and similar sheet materials.

Drop-in fit for RTY-2 handles

The blades match the RTY-2, RTY-2/DX, RTY-2/G, RTY-2/NS and related models without adapters. A .3 mm thickness keeps the cutting geometry consistent so the handle’s depth stop and safety latch work as designed. No extra washers or shims are required, freeing up bench time otherwise spent on fitting. The dispenser snaps shut, preventing loose blades from scattering in a tool bag.

Five-blade supply for high-volume cutting

Tungsten carbide holds an edge longer than standard steel when slicing vinyl, upholstery, tarp or heavy fabric. Five blades give enough reserve for multiple large projects before reordering. The straight profile excels on long, clean cuts but is not suited for curved patterns or rotary pinking. Users needing decorative edges or very tight radii should choose a different blade style.

Questions about this item

How long will the 0.3 mm tungsten carbide edge stay sharp when cutting fabric all day?

The 0.3 mm tungsten carbide steel resists wear far longer than standard steel, so a single 45 mm blade handles extended fabric, leather or vinyl sessions before needing rotation.

Does the blade generate noticeable heat or vibration during continuous rotary cutting?

The precision-ground 45 mm round edge runs smoothly in compatible RTY-2 cutters, producing minimal friction heat and no perceptible vibration during prolonged use.

Which rotary cutter models accept these 45 mm blades straight from the dispenser?

They fit Olfa RTY-2 series cutters including RTY-2/C, RTY-2/DX, RTY-2/G, RTY-2/NS, RTY-2C/NBL and RTY-2DX/PBL.
