View full details

In 1961, the original EH-3 multiple spindle drill was introduced to the print finishing industry. Today, the original is still the best and will be a valuable asset for any print shop. 

The rugged steel and cast iron design of the Eh-3 provides accurate drilling for years to come. Powerful hydraulic operation minimizes operator fatigue and results in consistent, clean holes. The taper-fit shank design ensures that drill bits will seat centrally and securely into the spindle. The EH-3 can drill 25% more stock on every stroke with its standard 2-1/2" drill bits. 

The EH-3 utilizes an automatic-return of the drilling heads as standard equipment, minimizing the contact between the drill bits and the drilling block. This allows for longer intervals between sharpening and longer bit life.
