CLAUSING 2276 UPRIGHT DRILL PRESSES

Technical Description

The Clausing 2276 Upright Drill Press is a heavy-duty floor model designed for precision drilling with a 20-inch swing and a powerful 1.5 HP two-speed motor operating at 208-230 VAC, 3-phase power. It features an infinitely variable spindle speed ranging from 150 to 2,000 RPM across two ranges: low (150-1,000 RPM) and high (300-2,000 RPM), controlled by a variable speed sheave pulley drive with a two-speed switch. The drill press accommodates a 1.25-inch capacity for hand feeding in mild steel, with drilling capability up to the center of a 20-inch diameter circle. Its spindle system includes a #3 Morse taper (3MT) on a 2.5-inch diameter quill with 6.5 inches of travel, supported by eight ball bearings—including a lower double-row bearing to absorb radial and thrust loads—ensuring smooth, accurate operation. The working table surface measures 22 inches by 19.5 inches, equipped with ½-inch cored T-slots on 9-inch centers, and is adjustable for height, with a maximum spindle-to-table distance of 33.125 inches and spindle to base distance of 43.375 inches. The column is constructed from 4-inch diameter ground steel with a 3/16-inch wall thickness and stands 66 inches tall, providing rigidity and support. Additional features include a mesh top belt guard, telescopic spindle guard, thread-adjustable depth stop, and optional accessories such as an E-stop switch, forward/reverse control, and coolant system. The machine weighs approximately 600-700 pounds and measures 22 x 36 x 69 inches (LxWxD), making it suitable for industrial and professional workshop environments requiring versatile and robust drilling capabilities.
