Manual

This single unit construction Line Boring Machine has all the features to do case goods and framework, furniture fittings and 32mm line boring. The fully adjustable boring head can drill vertical or horizontal, and will lock at any angle in-between. The 2-1/2HP motor provides plenty of power at 2800 RPM at the spindles. Hardened steel gears transmit power to the 21 spindles, assuring many years of performance. A large table size of 35 x 17-1/4 offers generous support for your workpiece. With the 60" adjustable back fence, simply set any of the 4 flip stops for exact repetitive drilling. Twenty-one quick chucks also come standard, allowing hand removal of all bits for tool-free, rapid set-ups. The unique flip down fences have built-in magnifiers for easy tape reading and stay attached to the machine, making it simple to change over from case goods to line drilling. A six-position turret stop makes drilling depth adjustments simple. The clamp bar features a grip-tight surface assuring pneumatic work hold-downs stay in position.
