CHALLENGE EH-3 3 SPINDLE DRILL

The EH-3 model of paper drills have been the industry-standard for over 40 years, with over 50,000 units sold worldwide. 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 our 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.
