| The 3F-HB is the ideal tool for performing those difficult facing, grooving, back facing and counter boring operations on work pieces too large to turn or too bulky to handle with safety. Automatic feed is in the forward mode and is actuated by holding a knurled feed-ring. The 3F-HB features a gear drive that generates a continuous feed rate of .003 per revolution. To prevent damage to the gear train, an especially designed detent clutch automatically disengages when a preset stop is reached or when cutting pressures become excessive. 1-1/2-18 threaded back. |
