Pneumatic Stroke/Self-Feeding
Includes Compact Sealed Oil Cylinder Feed Control


Drill Units With Feed Controls Provide Accurate Feed Rates For Precision Applications.

This degree of accuracy is not always possible with pneumatic reciprocation alone (Models 150 & 250) where the compressibility of air allows for variations in feed rates with changes in thrust load, particularly when breaking through a hole.

  • Compact Sealed Oil Cylinder -- Low Cost
  • Simple Cylinder Plunger Depression to Actuate Feed Control
  • Controls a Segment or the Complete Drill Stroke Cycle -- 1/2", 1", 2", 3", 4" & 6"
  • Adjustable Positioning Produces Rapid Advance Which Saves Cycle Time
  • Suitable for Applications Requiring Forward Feed Control
  • Right, Left or Top Mounted Feed Controls Available for Maximum Application Flexibility
  • Top Mounted Feed Control Maintains 2" Minimum Centers for Multiple Unit Applications and Maximum Application Flexibility
  • Minimum Feed Rate 0.2 In./Min.
  • Maximum Feed Rate 240 In./Min.
