Pneumatic Stroke/Adjustable Hydraulic Feed Control • Self-Feeding

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.

  • Self-Contained Hydraulic Unit -- Does Not Require External Actuation
  • Provides Full-Stroke or Partial Feed Control -- 1-1/2", 2", 3", 4", 6" & 8"
  • Adjustable Positioning Produces Rapid Advance Which Saves Cycle Time
  • Forward Feed Control Standard -- Reverse & Double Feed Control Available
  • Skip-Feed, Stop-Feed & Multiple Feed Valve Options
  • Right And/Or Left-Side Mounts
  • Paired Mountings Reduce Spindle Center Distance To 2-1/8"
  • Minimum Feed Rate 4 In./Min.
  • Maximum Feed Rate 200 In./Min.
