Puma 1/2 Inch Reversible Air Drill - 400 RPM High Torque, Professional Pneumatic Drill with Auxiliary Handle (PUAT4041)

Heavy-Duty Power for Industrial Drilling

 

The Puma PUAT4041 is a robust pneumatic drill engineered for high-torque applications that demand precision and durability. Unlike high-speed smaller drills, the PUAT4041 is geared to deliver a powerful 400 RPM, making it the ideal choice for drilling larger diameter holes in thick metal, hardwood, and industrial composites. As a pneumatic tool, it offers a superior power-to-weight ratio and can operate continuously in demanding workshop environments without the risk of electrical overheating.

Designed for maximum user control, this 1/2 inch (13 mm) drill features a reversible motor with a conveniently located lever for quick directional changes. To manage the high torque output safely, it comes equipped with a sturdy auxiliary side handle, providing the stability needed for heavy-duty boring. With its industrial-grade keyed chuck and ergonomic pistol-grip design, the PUAT4041 is an essential tool for heavy vehicle maintenance, structural steelwork, and industrial manufacturing.

Top 3 Frequently Asked Questions

1. Why is the RPM lower on this model than the 3/8 inch model? The lower 400 RPM is a deliberate design choice to provide higher torque. When using larger 13 mm bits, you need more "twisting power" and slower speeds to cut through thick material effectively without burning out the drill bit.

2. Does this drill require a special air setup? It operates on the standard 6.3 Bar (90 PSI). However, because it is a larger tool, ensure your compressor has a sufficient tank size and CFM (Cubic Feet per Minute) rating to maintain consistent power during deep drilling.

3. Is the auxiliary handle mandatory? While the tool can be held by the pistol grip, using the auxiliary handle is strongly recommended. It provides the necessary leverage to prevent the tool from twisting in your hand if the drill bit binds in the material.
