DRILL BITS, DI HOLE CUTTERS AND CENTRE DRILLS
Description and benefits
The OPTIMQ drill bits and DI hole cutters have been designed to drill ductile iron and fibre cement pipes.
DI drill bits are used to drill in ¾”, 1″ and 1¼’’. They are made of high-speed tempered blued steel with a special thinning for the cast.
The DI hole cutters are used to drill from 1½’’ to 4’’. They are made of epoxy-coated tempered steel with small silver-welded tungsten carbide plates that provide the pieces with high resistance and durability.
