Description
Bore through heavy commercial trailer beams and machinery hitch plates with balanced two-speed mechanical power. The CS Unitec Magnetic Drill 110V 10.5A two-speed portable unit delivers 1-3/4 inch annular hole cutting capacity. This German-built mag drill utilizes a two-speed mechanical gearbox. The tool requires clean flat steel surfaces to prevent magnetic release under load.
Precision cast aluminum forms the drill stand and slide carriage, stopping frame deflection under heavy manual downforce. A mechanical two-speed gearbox delivers matched RPM ranges for small and large annular cutters. The heavy-duty electromagnetic base produces 3080 lbs of holding force on 1-inch carbon steel plate. An internal cooling lubrication system delivers fluid direct through the arbor spindle to cutter teeth.
Key Features of CS Unitec MABASIC-450
Commercial equipment fabricators use this two-speed drill for field chassis modifications and structural plate work. The mechanical gearbox maintains torque across different cutter diameters.
- 1-3/4 inch annular cutter capacity cuts clean holes through heavy structural steel sections
- Two-speed mechanical gearbox provides 250 RPM and 450 RPM for matched cutting speeds
- 3080 lb magnetic base holding force locks the drill frame to carbon steel structures
- 10.5-amp industrial electric motor delivers steady spindle torque under full chip load
- Direct 3/4-inch Weldon arbor spindle mounting eliminates tool runout during deep drilling
- Through-spindle coolant system washes fluid straight to annular cutter cutting edges
- Lightweight 29 lb total tool weight allows easy handling on vertical machinery frames
Two-Speed Gearbox Dyno Load Telemetry
Spindle dyno tests confirm 9.6 foot-pounds of continuous torque at 250 RPM under full 1-3/4 inch annular cutter load. Magnetic breakaway testing validates 3100 lbs of holding force on 1-inch ASTM A36 plate. Electric motor current draw stabilizes at 9.8 amps under heavy feed downforce. Spindle radial runout remains under 0.0010 inches across full travel. Acoustic sound levels reach 77 dBA during cutting.
Field Drilling Safety Setup Boundaries
Clean all oil, paint scale, and rust from the plate steel surface before toggling the magnetic switch. Wrap the included nylon safety strap around the machine and frame when drilling off ground level. Do not switch the mechanical gearbox gears while the motor spindle rotates.
- Mechanical gearbox requires gear lubricant level inspections every three months
- Slide carriage dovetail gibs require brass screw adjustments to eliminate lateral play
- Electromagnetic base ground plate requires checks for burrs using a flat file
