Sumitomo Electric Carbide Inc.'s WDX series large-diameter drill line now includes WDX-L coolant-through models. Reducing the cost per part, the WDX-L indexable drill features side port coolant. Because not all spindles are coolant-through, the WDX-L allows for the use of coolant through the side port. WDX-L diameters range from 0.5625" – 2.5000" in 4XD drill body lengths. The WDX-L accepts the same inserts as Sumitomo's conventional WDX series (WDXT inserts).

Diameters of the conventional WDX range from 0.5625" – 2.625" in 2XD, 3XD and 4XD drill body lengths. The WDX series is available in inch and metric sizes.

Sumitomo's vast selection of WDX and WDX-L bodies reportedly deliver a proven design for stable drilling. All drill bodies come with a four-cornered indexable insert design to provide a cost-effective drilling solution and easy tool management. The series uses two inserts per drill, regardless of diameter size. Insert grades for a longer tool life include ACP300 for steel, ACK300 for cast iron and DL1500 for aluminum.
