The following article ran in the February 1950 issue, when Pest Management Professional was named Pests. (View a PDF of the original article.)
One of the problems in termite control work has been the difficulty of drilling through concrete or other masonry to flood the area adequately with chemicals. Wood boring has been relatively quid and easy; but drilling to hidden beams, sills, or ground through cinder block, cement, pebble-dashing, or tile has usually been a major operation. The operation is hard, tedious, and time-consuming. The new Ingersoll-Rand electric lmpactool makes the job of masonry drilling easy, With the tool running a carbide bit, it is claimed holes can be drilled in less than half the usual time and with very little effort, been use of the unique impact principle on, which the tout operates. It is reported that on one job, drilling through extra hard 4″ concrete took one minute per hole with the impact tool, while an ordinary electric drill and carbide bit, took three to five minutes per hole. Other labor costs were also reduced. One man was able to handle the impact tool alone.; two men were required to obtain adequate pressure with a conventional electric drill.
Since the Impactool runs on 110 volt AC or DC current it can be plugged into any convenient electric socket. Here’s the way it works. Pressing the trigger sets the spindle revolving and the tool operates like any conventional electric drill until resistance to turning is met. Then a patented spring – hammer – anvil mechanism automatically goes into action and releases hundreds of powerful rotary impact blows to the work, thus providing the extra power necessary to turn the bit. When drilling brick, cinder block, con crete, tile, or other material which is especially resistant, the electric impact tool is said to give a more powerful turning effect than is produced by any other type of electric tool of comparable size. Since the motor is reversible, the drill can be quickly backed out of the hole when the job is finished.
An additional impact tool feature is that the worker does not tire easily. There is no torque re-action transmitted to the handles to induce operator Fatigue. This feature, combined with streamlined design, enables the operator to use that tool in confined spaces or work close to side walls.
Since the impact tool drills quickly and rums easily the PCO can handle more jobs per day.
Although the impact tool’s greatest usefulness to pest control operators is in its powerful rotary impacts which enable it to readily tackle tough jobs, a further feature is its low maintenance coats which is particularly important when the tool is used for continuous drilling. It is designed and built so that the motor continues to run even if the spindle should stall completely, This tend, to eliminate motor burnout, expensive repairs, and the loss of the tool while out of service for repairs
While the impact tool is used in termite control mainly for drilling or wood boring, it can be used for a variety of other operations. It is an all-purpose tool, available in two sizes. With standard accessories the Size 8U will drill steel up to 3/8″ diameter or step-drill to 3/4″ diameter (in addition to drilling masonry up to and boring wood up to 11/4″.) It will run nuts, extract broken cap screws and studs, and drive and remote studs up to 5/8″ bolt size. It will also do tapping from 3/8″ to 3/4″, drive machine screws up to 2″ and wood screws up to No. 22, do hole saw work up to 2″, and run wire brushes up to 1/2″ shank. The Size 8U tool weighs 9 pounds, 14 ounces, and the smaller Size 4U model, rated up to 3/8″ bolt diameter, weighs only 6 1/2 pounds.
With hard work removed from masonry drilling, and at least 50% of the time saved doing this job, it is found that the new impact tools are greatly simplifying and making more profitable the job of termite control.
Impactools are manufactured by Ingersoll-Rand Company, 11 Broadway, New York 4, New York.
