Description
Drill structural holes on coated machinery bodies or thin steel plates without losing magnetic clamping force. The Fein Slugger JMU 137-PQW Magnetic drill delivers 1-3/8 inch annular cutting capacity using a permanent magnet base. This German-engineered drill features a patented permanent magnet. It holds fast on painted or thin sheet steel where electromagnets fail.
Precision die-cast aluminum forms the drill slide frame, eliminating motor twist under heavy feed lever pressure. The patented permanent magnet base requires zero electricity to hold grip, eliminating drop hazards during sudden shop power cuts. A high-torque electric motor pairs with an electronic speed control module and forward/reverse rotation for thread tapping. The QuickIN tool-less clamping system swaps cutters in seconds.
Key Features of Fein 72707361090
Field mechanics use this permanent magnet drill to service painted equipment chassis and thin sheet metal. The permanent magnet base maintains holding power during power outages.
- 1-3/8 inch annular cutting capacity bores clean holes through structural plate and sheet steel
- Permanent rare-earth magnet base holds fast without electrical power or cord dependencies
- High-traction base holds on painted surfaces and thin steel down to 3/16-inch thickness
- Electronic speed control provides adjustable RPM for drilling, reaming, and thread tapping
- Reversible motor rotation enables mechanical thread tapping up to 1/2-inch diameter
- Patented QuickIN tool-less mounting system swaps annular cutters without allen wrenches
- Integrated tilt sensor cuts motor power if the magnetic base breaks loose from the workpiece
Permanent Magnet Pull Dyno Telemetry
Tensile pull testing verifies 2050 lbs of holding force on painted 1/2-inch plate steel. Base adhesion measures 1400 lbs on 3/16-inch steel plate without electrical assist. Spindle torque output reaches 7.4 foot-pounds at 350 RPM under full annular cutter load. Motor current draw measures 9.2 amps during 1-3/8 inch hole drilling. Acoustic sound levels register 75 dBA during active metal cutting.
Permanent Base Drilling Safety Boundaries
Rotate the mechanical clamping lever to full stop to engage the rare-earth magnetic arrays. Attach the safety ratchet strap around the machine frame when operating in vertical or overhead orientations. Do not operate this permanent magnet unit on non-ferrous aluminum or brass without steel backing plates.
- Permanent magnetic pole faces require clean cloth wipes to remove clinging steel chips
- Slide track dovetails demand weekly application of ISO 68 machine way lubricant
- QuickIN tool holder collar requires solvent flushes to clear out metal cutting debris
