Jet JT9-505451 5 Inch Angle Grinder 0.9 Hp

Product Description

The JET JT9-505451 is a 5-inch pneumatic angle grinder designed for grinding, cutting, and surface preparation in demanding trade and industrial environments. Powered by a 0.9 HP motor, the tool delivers strong torque through precision spiral bevel gears that transfer power directly to the spindle, supporting consistent performance and long service life. The variable-speed throttle ramps up to maximum RPM, giving the operator control over material removal rate. Weighing 5 pounds, the grinder is light enough for extended overhead or positional work. Licensed tradespeople and fabricators working in metal, mechanical, and construction applications will find the power-to-weight ratio practical for sustained use on the job.

The JT9-505451 is suited for metal fabrication shops, mechanical contractors, and maintenance trades requiring a compact, air-powered angle grinder for weld dressing, deburring, and surface work. The two-position auxiliary handle accommodates both right- and left-handed operators and adapts to flat, vertical, or overhead grinding positions. The toolless wheel guard swivels 360 degrees with 9 preset positions, allowing quick repositioning without interrupting workflow. Grinding wheel is not included and must be sourced separately to match the application and material.
