FOR ANNULAR CUTTERS POWDER STEEL + HSS-XE STEEL PRECISION OF THE BOREHOLE / PRODUCTION TOLERANCES OF THE CORE DRILLS Steel < 500 N Stainless steel Aluminium Steel < 750 N Steel < 900 N Steel < 1200 N Steel < 1400 N Grey cast iron Brass Copper Railtracks Hardox 400, 450 Inch The accuracy of the hole depends on the tolerances of the annular cutters and the precision of the machine (spindle). Core drills are mainly used on magnetic hole cutting machines which mostly have high spindle tolerances. Therefore, the holes are usually slightly larger than the diameter of the core drill. For this reason, the core drills are manufactured in minus tolerances (see table). If holes are made with an annular cutter on high-precision spindle machines, an undersize is therefore possible.
