Series 28 - 3/4 HP and 1 HP

   These units can tap as well as drill. The motor automatically reverses for withdrawal after tapping. This system requires no mechanical parts, gears, clutches, or lead screws. It eliminates the major cause of problems in ordinary tapping machines. The Series 28 is capable of tapping class 2 threads in a range from #4-40 to 1/2-13 threads per inch. It has all the versatility of the Series 60 including the capability of drilling and shares the low air consumption requirements of all Dumore Autofeed Drill units-5 SCFM or less. These units will accept multiple spindle drill heads.

 

 

Series 60 - 1/4 HP and 1/3 HP

   The Series 60 is a compact (approx. 4.3”x27”) variable speed autofeed drill unit readily adaptable to close-center drilling applications. The Dumore permanent-magnet motor (high and low speed versions) has an infinitely variable speed control. No pulleys or gears to change and the unit is nose-mounted so you can remove it quickly and easily-then remount it to the precise former location. Although it’s compact, the Series 60 delivers maximum drilling capability with a full 300 lbs. of thrust at 100 psi air pressure and a 3” stroke.
