Ball Bearing Sensitive Radial Drill » I HE object of a new high speed radial drill, developed tion minimizes the time between holes, while high speeds I by the Fosdick Machine Tool Company, CincinnatiOhio, is to drill and tap work of too large an area forthe high speed sensitive upright drill. The rapidity of posi-tioning the drill, together with ease and convenience of opera-. Fosdick Radial for High Speed Drilling of Large Worl< and excess power reduces the actual drilling time. The table is readily removed, allow-ing 49^/^ in. betweenthe spindle and base, which has a working surface of 28 36 in. and is planed and provided with T-slots. The ver-tical movement of the table is 16 in. through a ball-bearingtelescopic screw. The working surface is 20 in. by 33 21 in. maximum to the spindle. The arm, sensitive in its movement, may be svmng com-pletely around the column, and is supported on both annularand thrust ball bearings on the column, which extendsthrough to the top. The spindle, as all other revolving mem-bers, is equipped with ball bearing journals. It has a No. 2Morse taper, and a vertical traverse of 8 in. The horizontalmovement of 28J/^ in. along the arm is through rack andspiral gear with the handwheel to the right. This position ofthe hand wheel enables the operator to swing the arm andmove the head simultaneously with the right ha
