Description
Bore massive six-inch diameter holes through heavy machinery frames, crane booms, and structural building girders. The CS Unitec 6 Inch Magnetic drill with 12-inch stroke delivers heavy industrial boring capacity on steel structures. This giant mag drill features a four-speed mechanical gearbox. It requires heavy overhead hoist assistance to position its 112-lb frame safely.
Heavy cast-steel construction forms the upright column and slide housing, resisting immense feed pressures without frame twist. A four-speed oilbath gearbox matches motor torque across drill sizes from 7/16-inch up to 6 inches in diameter. The high-density electromagnetic base generates 5400 lbs of holding force. A Morse Taper 4 spindle interface accepts heavy annular cutter arbors, twist drill chucks, and industrial pipe reamers.
Key Features of CS Unitec MAB-1300
Heavy shipyard fabricators and crane mechanics use this giant magnetic drill to bore massive hinge pin holes. The 12-inch stroke length accommodates deep hole boring setups.
- 6-inch annular hole cutting capacity bores massive holes through heavy industrial steel structures
- 12-inch total quill stroke length handles deep structural channels and tall drill fixtures
- Four-speed mechanical gearbox provides matched speeds from 30 RPM to 380 RPM
- Morse Taper 4 spindle mounting accepts heavy-duty industrial arbors and tooling adapters
- 5400 lb magnetic base clamping force anchors the drill securely against steel columns
- Reversible 20-amp electric motor allows mechanical thread tapping up to 1-5/8 inch
- Automatic internal cooling lubrication feeds fluid direct through the arbor spindle
Heavy Boring Dyno Torque Telemetry
Spindle dynamometers measure 148 foot-pounds of torque at 45 RPM under full 6-inch annular cutter load. Magnetic base tensile retention tests confirm 5450 lbs on 1-1/2 inch thick ASTM A36 plate. Electric motor current draw peaks at 19.4 amps during heavy boring through 2-inch structural plate. Spindle deflection measures under 0.0015 inches under 600 lbs of manual feed downforce. Sound output measures 81 dBA during continuous heavy cutting.
Industrial Drilling Guardrails Negative Filters
Rig an overhead crane strap through the lifting lug before moving this heavy drill onto vertical steel surfaces. Engage the magnetic base switch and verify the green LED interlock indicator before switching on the motor. Never attempt to operate this high-tonnage machine on steel plate under 1/2-inch thickness.
- Four-speed gearbox requires industrial gear oil inspection and changes every 200 hours
- Quill slide brass gibs require tension adjustment to remove lateral spindle play
- Electromagnetic base bottom surface demands solvent cleaning before every mounting
