Designed for high-production drilling applications, the Ingersoll Rand 8266-A23-2 self-feed offset drill combines a 3/16" drilling capacity, 2,300 RPM free speed, and double gear reduction to deliver controlled, repeatable drilling performance in demanding manufacturing environments. Its self-feed mechanism automatically advances the drill into the workpiece, helping improve hole consistency while reducing operator effort during repetitive production operations.
The offset head configuration provides improved access when drilling near flanges, edges, and structural obstructions where conventional inline drills may not fit. Designed for continuous-duty industrial service, the 8266-A23-2 combines pneumatic reliability with automatic feed control to support aerospace, transportation, fabrication, and general manufacturing applications that require accurate, repeatable hole production.
