Supplied in 16xD and 20xD sizes and suited for use on ISO-P and ISO-K materials, DC170 internally cooled drill features land design that orients margins radially and copper-color finish (DPP Coating). Lands have shallow cooling grooves at drill end, and 8 visible cooling grooves can be used as scale for regrinding. Coolant flow encompasses entire drill point, optimizing cooling while also inhibiting chip packing. Amount of material behind cutting edge enhances sturdiness.
