Dotco 15LF283-72 Right Angle Air Drill 0.40 Hp

Product Description

The DOTCO 15LF283-72 is a right angle pneumatic drill built for production and maintenance applications where access is tight and a straight drill cannot reach. Rated at 0.40 HP and 3,300 RPM, it accepts a 1/4-inch keyed chuck for secure bit retention under sustained use. Operating at 90 psi shop air, the tool delivers consistent rotational speed for drilling metal, plastic, and composite materials in confined work envelopes. At 1.5 pounds and 10 inches in overall length, it is compact enough for one-handed operation in close-quarters environments. Licensed HVAC technicians, industrial maintenance mechanics, and sheet metal workers are the primary installers of this tool.

This right angle air drill is suited for automotive, aerospace, and general industrial assembly lines where inline drills cannot access fastener locations. The 90-degree head angle allows drilling parallel to a work surface or into recessed cavities. The 1/4-inch keyed chuck accepts standard twist bits and step bits commonly used in sheet metal and light structural work. The non-reversible spindle keeps the design simple and the tool lightweight for repetitive-cycle production use.

Key Features

• Right angle head for drilling in confined or recessed spaces
• 3,300 RPM free speed for efficient material removal in light-duty drilling
• 1/4-inch keyed chuck provides positive bit retention and easy bit changes
• 0.40 HP pneumatic motor runs on standard 90 psi shop air supply
• Compact 10-inch overall length at 1.5 pounds for one-handed use
• Non-reversible spindle reduces mechanical complexity and tool weight

Compatibility

Designed for use with standard 1/4-inch keyed chuck tooling on any compressed air system supplying 90 psi with a 1/4-inch NPT inlet connection.

Installation Notes

Connect to a regulated air supply set to 90 psi using a 1/4-inch air line fitting; ensure the supply line is drained of moisture before use to protect internal motor components. Verify the keyed chuck is fully tightened with the chuck key before operating the drill. Do not exceed the rated air pressure, as overpressure can increase RPM beyond the design limit and reduce tool service life. Service and repair should be performed by a qualified pneumatic tool technician in accordance with the manufacturer's maintenance guidelines.
