Jet 320033 J-720R 3HP Radial Drill Press Jet 320033 J-720R 3HP Radial Drill Press
• The power train gears and spline shafts are made of the finest quality, heat treated and ground nickel-chrome steel, giving extra strength and smoothness to high torque loads
• The spindle is made of finest case hardened steel, for extra strength and wear
• The spindle is supported by double row taper roller and thrust ball bearings at the nose, with thrust and radial axis bearings at the top
• Build to withstand exceptionally heavy drilling and boring loads to insure maximum accuracy
• Arm raising safety device prevents arm from dropping
• Counter balanceed mechanism for spindle return
• 6 Speeds/3 Feed rates make exotic materials easier to drill, bore and tap
• Centralized control center
• Automatic tool ejector
• Independent arm electric clamping system, which locks and unlocks the head and column
• Push botton controls are all reduced to 110VAC
• Electrical circuits are located in the build-in control box at the rear of the arm. This keeps the controls dust-and-humidity-free while making them easilly accessible for maintenance
• Entire frame is made of Meehanite and high tensile strength cast iron to handle the heaviest of jobs
