Oscillating Drilling Tool Holders - Model 70MRDA

                                                Model BBMRDA, Multiple Spindle

Heat, long string chips, and drill breakage are all factors which

must be considered in drilling operations. The oscillating action of the

deep-hole drilling tool breaks the chips into fine granules, eliminating the chip

problem and affording longer drill life through cooler running. In addition,

finer finishes, closer tolerances, and better concentricity are maintained.

The oscillating motion is derived from a flutter or wave cam built into the tool.

It oscillates .006", three times per revolution of the drill. The tool is driven by

the drill speeder spline shaft.

In order to cut freely, a drill must run at the highest surface speed possible

without burning the drill. If the spindle speed of the job is not high enough, the

revolving type tool is used to increase sfm. By revolving the drill in the

opposite direction from the spindle, it is possible to attain improvement in

concentricity. It will also afford faster cycle time and longer drill life.

Variations in drill speed can be obtained by utilizing the various gear ratios

available on the drill speeder drive of the machine.

Four sizes of Boyar-Schultz Oscillating Drilling Tools are available.
