Introducing the T33963 20" Floor Variable-Speed Tapping Drill Press

Your Precision Solution for Threaded Holes

Elevate your threading capabilities with the T33963, a floor drill press designed for precision when cutting threaded holes. With a robust 5/8" tapping capacity, this drill press delivers the additional functionality required for your specific thread patterns.

Featuring two variable-speed spindle speed ranges and a digital readout, adjusting the speed to meet your needs is effortless. The spindle comes equipped with auto-reverse functionality, enhancing efficiency during tapping operations.

Positioning is made easy with the 360° headstock, while the stability provided by the cast-iron base ensures a secure operation. The Class II laser eliminates guesswork by preventing alignment mistakes, ensuring precision in every project.

An integrated LED work light below the headstock provides extra illumination, and the rack-and-pinion table elevation control allows for seamless and precise adjustments based on your material thickness.

Safety is paramount, and the clear, square chip guard, complemented by a micro switch, not only protects the user from debris but also shuts off the drill press if the guard is open.

Crafted by our U.S.-based Technical Documentation Department, the T33963 manual is comprehensive and user-friendly, facilitating easy assembly and maintenance.
