CLAUSING 2277-A UPRIGHT DRILL PRESSES

Technical Description

The Clausing 2277-A Upright Drill Press is a robust industrial drilling machine designed for precision and durability. It features a maximum drilling capacity of 0.75 inches in mild steel and 1.00 inch in cast iron. The drill press offers infinitely variable spindle speeds ranging from 150 to 2000 RPM, accommodating a wide range of drilling applications. It includes a 0.75 to 1.5 horsepower ball-bearing motor, with some models offering two-speed options to optimize performance and efficiency. The machine has a 20-inch swing, enabling drilling at various distances from the column center, and a large worktable measuring 22 by 19.5 inches, equipped with ½-inch cored T-slots spaced 9 inches apart for secure workpiece mounting and adjustment. The solid 4-inch diameter column provides rigidity and stability, supporting a spindle travel of 6.5 inches and a maximum spindle-to-base distance of approximately 25.4 inches, allowing for deeper drilling and larger workpieces. The spindle features a Morse Taper 3 (MT3) nose taper for compatibility with standard tooling. The drill press stands approximately 69 inches tall with width and depth dimensions of roughly 22 by 36 inches, and weighs about 700 pounds, ensuring stability during operation. Electrical configurations commonly include 480V 3-phase power, with motor speed options at 900/1800 RPM or infinitely variable speeds. Additional features include a forward/reverse spindle direction switch, optional power feed, adjustable table elevation mechanism, and manual feed crank, facilitating versatility for various industrial drilling tasks. This machine is designed for heavy-duty use with precision control, suitable for machine shops and manufacturing environments requiring consistent and accurate drilling.
