The Starlock AIZ 28 SC cutter provides reliable and easy cutting of various soft materials. The sharp blade is ideal for slicing through pliable materials. It features a razor-like continuous cutting edge on both blade sides along with a sharpened tip for effortlessly piercing and slicing through flexible materials. The rigid scraper body made from HCS (high carbon steel) cuts through soft materials easily as its wide blade will not flex or warp mid-cut. This cutter is designed for use on soft expansion joints, putty materials like sealing compounds, insulation materials and soft joint materials. The Starlock Snap-In mounting system allows fast blade removal and exchange within 3 seconds without having to touch the blade. The mounting system produces the highest power transfer due to a 3-dimensional tight-fitting connection between machine and accessory.
