Delta / Rockwell 15-120 30" Ram-Type Radial Arm Drill Press | 7" Stroke | 3-Phase

Rockwell 30" Ram-Type Radial Arm Drill Press

Model: 15-120 (Industrial High-Performance Series)

Type: Ram-Type Radial with 7" Deep-Hole Stroke

Condition: Professional Grade / Fully Operational

The Ultimate in Workshop Versatility

The Rockwell 15-120 is not your standard vertical drill press. Known in the industry as the "Unidrill," this machine features a heavy-duty horizontal ram that allows the head to reach the center of workpieces up to 60 inches wide. Whether you are drilling compound angles in custom furniture or large-format metal baseplates, this machine provides the rigidity and reach that modern imports simply cannot match.

Technical Specifications

• Throat Capacity: Massive 30" to 32" reach (Spindle to Column).
• Quill Travel: 7" Stroke—ideal for deep boring and long-bit applications.
• Spindle Speeds: 16-speed capability ranging from 175 to 8,200 RPM via an integrated jackshaft system.
• Head Tilt: 90° Total Travel (45° Left / 45° Right) with precision scale for compound angle drilling.
• Ram Movement: Horizontal travel from 13" (retracted) to 31" (extended) along a precision-machined cradle.
• Vertical Capacity: 16" of travel on the column with a maximum spindle-to-table "daylight" of 20".

Premium Features

• T-Slotted Production Table: Includes a heavy 18" x 26" cast-iron working surface with an integrated oil/coolant trough for professional metalworking setups.
• Industrial Power: Equipped with a 1/2 HP, 230/460V 3-Phase motor, providing constant torque across the entire speed range.
• Precision Cradle: The ram slides through a heavy cast-iron housing with adjustable eccentric bearings to ensure zero-deflection, even at full extension.
• 360° Column Rotation: The entire ram assembly can swing completely around the column, allowing you to drill workpieces secured to the floor or an external bench.

Dealer Note: "This specific unit features the sought-after 7-inch stroke, which is significantly more versatile than the standard 4-inch models. Built in the USA during the peak of Rockwell/Walker-Turner engineering, it remains one of the most space-efficient ways to add large-scale radial drilling capacity to a shop without the footprint of a full industrial radial arm drill."
