The 15-344 includes motor and controls, belt and pulley guard, belt and motor pulley (supplied wit 5/8 in. bore unless 1/2 in. bore is specified), self-locking depth stop, depth gage, 65-104 self-ejecting chuck key, instuction manual. Extra-large spindle bearings 6 PLUS 6 and VS6 spindle and spindle pulley are supported by four over-sized, pre-loaded, lubrcated-for-life ball bearings. Massive quill is a full 2 in. diameter.

This fine combination of features assures freedom from chatter, long, maintenance-free life and maximum pressure at the drill point. Wide, test-proven speed range gives you a true 10-to-1 speed ratio. You get the exact speed you need for every drillingjob on any material- 450 to 4700 rpm with a 1725 rpm motor and 300 to 3100 with an 1140 rpm motor. Quick belt tension release is provided by the pivoting motor mounting plate which has a reverse, self-locking taper on the spring loaded, rubber-tipped plunger that quickly restores correct belt tension. Extra-long quill travel gives the extra depth you need for deep-hole jobs like skip and gang drilling. PLUS, the extra stroke required for clearing jigs and fixtures. Six speeds offer unbelievably wide range of speeds with a low-cost 1725 rpm motor- 425, 600, 1100, 2050, 3900 and 5500 rpm- 11.8 to 1 speed ratio. You can choose an extra-slow speed for drilling very hard materials. an extra-fast speed for working soft materials. or an optimum speed for any size bit material. Efficient variable-speed drive lets you select any spindle speed instantly while machine is running. A self-locking cam, plus a snubber feature, hold speed settings constant under all load conditions. Proper belt tension is automatically maintained for full power transmission.
