Precise 18mm Tungsten Carbide Rotary Cutter

The Olfa RTY-4 is a new hand tool built for intricate cutting tasks. Its 18mm tungsten carbide blade handles detailed fabric and paper work with a straight handle design. A plastic blade cover protects the edge during storage. The tool weighs 0.06 and measures 5 1/2 inches in overall length.

Suited for detail work, not heavy stock

This cutter serves quilters, crafters and hobbyists who need fine control on lightweight materials. The small blade diameter limits cutting depth on thick stacks or dense substrates. Buyers who need to slice multiple heavy layers or tough composites should look at larger rotary cutters or shears instead.

18mm blade diameter defines cutting scope

The 18mm tungsten carbide blade sets the maximum cut depth and detail radius for this model. It determines whether the tool fits your pattern curves and material thickness. Match this diameter to your project requirements before purchasing.

The 18 mm tungsten carbide blade is sized for intricate and detailed cutting of fabric and paper, allowing tight curves and precise trimming.

How does the tungsten carbide blade material perform in a real project?
