Narex half round cabinet rasp is carbon steel, hardness 49 hrc, hand-cut blade. Stained hornbeam wood, waxed handle. 395Mm total length. Hand-cut: hand-cut rasps function differently from machine cut rasps. They cut faster and leave a surprisingly good work surface because of the excellent surface quality, extra sharpness and the slightly irregular spacing of their teeth. Use: used for fine shaping work by quickly removing a large amount of wood while leaving a smooth surface. Come in coarse, medim and fine grains. Size: 250 x 28 x 6mm coarse.
