Rotary trimmer with a 28" cut length is made for precision and accuracy. Self-sharpening cutting system means there's no need to worry about replacing dull or worn blades. The blade's precision-graduated edge will remove even the tiniest sliver of paper and produce a clean, burr-free cut. Extruded aluminum guide bar provides excellent strength and durability when cutting thicker materials. Dual-barrel design provides a smooth, stable track for the cutting head to power through dense material. Carefully screened rulers and guides help align your cuts. For added convenience, the grid includes standard-size guides for trimming photos and documents. Sturdy metal base provides a solid foundation that will never warp or crack. Integrated, automatic clamping system provides even pressure to prevent your work from shifting. Rotary trimmer is designed to cut up to 20 sheets at a time.Rotary trimmer with a 28" cut length is made for precision and accuracy.
