IR’s self-feed drills: Revolutionizing construction efficiency with precision automation

Self-feed drills by Ingersoll Rand

Dobco Equipment Ltd. is Canada’s leading supplier of innovative construction solutions by Ingersoll Rand (IR), which has satisfied businesses in the sector for more than a century and a half. IR’s broad selection includes three powerful lines of self-feed drills – the Bant-A-Matic, Par-A-Matic, and Super Par-A-Matic series. Construction workers can automate a wide range of secondary machining applications with the selection, performance, and precision that these self-feed drills provide.

Reliable rotary-vane air motor

These drills come with several important features: they use compressed air for the spindle rotation and the feed/controls function; each has a reliable rotary-vane air motor that offers high power-to-size performance, which increases flexibility in machine design with minimal tool size and weight; and only simple pneumatic circuitry is required for installation. These tools can be used individually or in conjunction with other IR electric and pneumatic tools, with speeds ranging from 350 to 19,000 revolutions per minute, and twin head spindles are available.

Each of these drills can be installed via a straightforward setup procedure. First, the thread guard should be removed (left-hand thread), and then the drill should be inserted in the mounting fixture; next, advance the drill to the workpiece and set the end of the stroke screw to the depth of the cut. The Hydraulic Check should be set to contact about 1/8 of an inch from the part. The user should attach the air line to the main inlet, install 9600 bleed valves, and attach the air line to the start and retract ports and buttons. Then adjust the feed rate down to zero and start the drill for a dry run – increasing the feed rate as necessary and putting the part in the fixture for a test run.
