Spade Drill Holders

Drill from 9.5mm up to 114mm using just 9 different sized holders!

Supercut holders are available for short holes to deep holes up to 25xD. As the insert is self-centering, deep hole drilling is possible with reliability and accuracy.

For holders 15xD and above, it is recommended that you pilot drill 1xD with a short length spade drill of the same diameter (do not pilot drill with a smaller diameter drill or drill point with a different angle - this will cause tool failure.) HSS or PM inserts are recommended for drilling above 7xD.

Weldon holders have through coolant supply from the rear of the shank. Morse taper holders have through coolant on the side of the shank above the morse taper. Machines without through coolant can be adapted by using a coolant adapter with a morse taper shank tool.
