ARO Peck-Feed Drills are designed specifically for applications where the hole depth exceeds four times the diameter of the drill bit. They offer the advantages of deep-hole chip clearance with close diameter and axial controls.

The ARO Peck-Feed Drill is a complete, self-contained unit. The pecking operation is controlled by a pre-set, timed sequence. Upon receiving a start signal, the tool automatically advances, drills to a selected peck depth and retracts, continuing the cycle until the total hole depth is reached. This sequential pecking action clears the hole and drill flutes of chips that produce frictional heat, drag, and drill skew. It also greatly increases the life of small drills (3/32 thru No. 80) that are sensitive to excessive thrust and radial loading.

Additional features / benefits include—

  • Manual and remote operation.
  • Muffled exhaust for a more comfortable work environment.
  • Selection of mounting brackets to meet installation requirements.
