Overview

The Powermatic 1150 is a legendary American-made drill press, favored by machinists and high-end woodworkers alike. Built in McMinnville, Tennessee, this 1973 unit comes from the highly regarded Houdaille era, known for its massive cast-iron construction and "overbuilt" mechanical components. This specific machine features the Step-Pulley drive system, which is widely preferred for its mechanical simplicity and bulletproof reliability compared to complex variable-speed heads.

Key Features

• Single Phase Advantage: Factory-wired for standard household/small-shop power. No phase converters or VFDs required.
• Precision Ground Table: Heavy cast-iron work surface with dual "T-slots" for secure fixture mounting.

Dealer Note: "Serial #315S905 is a prime example of why vintage Powermatic iron is still the gold standard. In an era of lightweight imports, this 1973 floor model offers a level of rigidity and quill precision that is hard to find today. If you want a machine that will hold its value and stay accurate for another 50 years, this is the one."
