Weldon shank spade drill bodies are ideal for milling machines/machining centres and are available for drilling from 9.5mm diameter to 65mm diameter. We recommend that you always use through coolant for drilling above 1xDiameter deep. Drilling deeper than 1xD deep without through coolant will result in tool failure.
Taper shank spade drill bodies are ideal for lathes or radial arm drills and are available for drilling from 9.5mm diameter to 114mm diameter. Holders come in drill series (e.g. A, B, C, D etc) which refers to the diameters that can be drilled. For example, a series C holder can drill 13.0-17.5mm diameter.
