D1 Ultra-Compact Portable Magnetic Drill with Maintenance-Free Rail Guide The D1 is an ultra compact magnetic drilling machine with maximum capacity of 1-3/8" (35 mm) diameter in 2" (51 mm) thick material. The unit features an ultra light weight of 22 lbs (10 kg). A maintenance-free rail guide travel system eliminates the necessity for alignment, maintains accuracy and reduces cutter breakage. The D1 is equipped with an electromagnetic Energy Saving Base (ESB) which uses only 50% of the power when the motor is not under load, dramatically increasing the operating life of the electromagnet, and a Magnetic Field Shape Control (MFSC) system which provides maximum holding power on thin material. A Magnetic Power Adhesion Control (MPAC) module detects adequate adhesive force of electromagnetic base before allowing drill activation for safe operation FEATURES 1-3/8" (36 mm) diameter x 2" (51 mm) depth of cut Ultra compact 14-3/4" working height (with coolant bottle) Adjustable cutter guard with built-in chip breaker Through spindle coolant system with removable reservoir Little maintenance with no gib adjustment and extreme accuracy Fewer parts which results in less run-out Lightweight û only 22 pounds Safe magnetÖ circuitry recognizes magnetic holding power Spring slug ejecting arbor system Magnet is 1/3 smaller, lighter and yet stronger Magnet uses 50% power when motor is not under load Maintenance free rail guide system Advanced motor for easy field service All aluminum parts are heat treated for rigidity
