MOULD AND DIE INDUSTRY 126 / NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING RESIN BONDED CUT-OFF WHEELS Resin bonded cutting wheels feature exceptionally good free-cutting characteristics due to low cutting forces and low cutting temperatures. The result is fast cutting with clean cut surfaces without edge chipping – which is particularly important for thinwalled hollow workpieces.
