Description
Bore clean holes through equipment trailer frames and structural steel tubing without hauling heavy shop equipment. The Evolution Power Tools 1-1/8 in industrial magnetic drill delivers 1-1/8 inch annular cutting capacity in a compact package. This portable drill features a 1200-watt motor. The electromagnetic base requires flat carbon steel plate over 1/4-inch thickness to hold firm.
Cast aluminum forms the slide column and motor housing, reducing carry weight to 24 lbs for easy jobsite portability. A single-speed 1200-watt electric motor delivers steady cutting torque through case-hardened reduction gears. The electromagnetic base produces 2860 lbs of holding force against carbon steel plates. An integrated gravity coolant reservoir feeds cutting lubricant through the center arbor pin, flushing metal chips out of the cut.
Key Features of Evolution S28MAG
Turf fleet mechanics use this compact magnetic drill to bore mounting holes in mower decks and utility trailers. The included chuck adapter allows switching between annular cutters and twist bits.

- 1200-watt industrial motor delivers steady 450 RPM spindle cutting speed under load
- 2860 lb electromagnetic base secures the drill to carbon steel workpieces without clamps
- Standard 3/4-inch Weldon shank arbor accepts standard commercial annular cutters
- Included 1/2-inch keyed chuck adapter converts the spindle for standard twist drill bits
- Integrated gravity coolant tank feeds fluid straight to annular cutter cutting edges
- Lightweight 24 lb tool mass allows easy single-mechanic positioning on vertical surfaces
Compact Spindle Load Dyno Telemetry
Spindle dyno tests confirm 4.8 foot-pounds of torque at 450 RPM under full 1-1/8 inch annular cutter load. Magnetic breakaway testing validates 2850 lbs of holding force on 1-inch ASTM A36 plate. Electric motor current draw stabilizes at 8.2 amps under heavy feed downforce in 1/2-inch plate. Spindle radial runout remains under 0.0012 inches across full quill travel. Acoustic sound levels reach 76 dBA during cutting.
Shop Operation Safety Negative Filters
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 operate this compact drill on thin steel sheet metal under 1/4-inch thickness.
- Slide carriage dovetail gibs require brass screw adjustments to eliminate lateral play
- Arbor coolant seals require visual inspection to clear out trapped metal chips
- Electromagnetic base ground plate requires checks for burrs using a flat file
