1966 Clausing 20" Variable Speed Drill Press

Model: 2287 | S/N 507634 | 1.5 HP Heavy-Duty Production Package

Overview

The Clausing 2287 is a legendary "Heavy Iron" drill press, widely considered the gold standard for 20-inch industrial machines. Manufactured in 1966, this unit comes from an era of superior American metallurgy, featuring a high-nickel-content cast iron head and a massive 4" diameter ground steel column.

This specific unit is equipped with the highly desirable Industrial Production Work Table, providing a massive 24" x 40" surface area for handling large panels, multi-part fixtures, or heavy assemblies that would overwhelm a standard tilting table.

Key Features & Dealer Benefits

• Infinitely Variable Speed Drive: Dial in the exact RPM required for the material while the machine is running. The high/low range capability provides maximum torque for large-diameter drilling and high-speed precision for smaller bits.
• Precision Head Assembly: All bearing surfaces were precision bored simultaneously at the factory to ensure perfect alignment. Eight ball bearings support the spindle, with a double-row lower bearing designed to absorb heavy radial and thrust loads.
• Massive Production Table: The large 24" x 40" working surface eliminates the need for makeshift supports and allows for the mounting of large industrial vises or rotary tables.
• Integrated Safety & Control: Features a top-mounted belt guard and a thread-adjustable depth stop for repeatable precision during production runs.
