Specification Amperage : 19.5 amps Brand : WeldingCity BulletPoint : Powerful Motor: Built with a high-performance pure copper motor, this machine delivers reliable power (4250W) and no-load speed (500rpm), ensuring consistent performance even in demanding drilling tasks, making it the ideal choice for professional engineering projects. BulletPoint1 : Premium quality electrical discharge machining (EDM, also known spark machining) tube electrodes (Copper) with single channel hole. 20-pcs per package. BulletPoint2 : Single hole (channel) copper electrode tubes. Tube length: 400mm; tube outer diameter (O.D.): 0.5mm and 1.0mm available. BulletPoint3 : Use in hole-popping EDM machines to create small holes, including pilot holes to run EDM wire through. BulletPoint4 : Copper EDM electrodes with single hole are inferior to Brass electrodes in creating through holes but wearing out much slower than brass electrodes. BulletPoint5 : U.S. based welding and hardware supplier. Strong technical support with experienced customer service to address buyer's any question. BulletPoint6 : Anchor stand is built with an aluminum column to prevent high torsional strength with smooth, hard wearing, adjustable guides and bearings BulletPoint7 : Anchor stand can be used with drill motors from various brands BulletPoint8 : IHT soft impact system enables an optimized, high-frequency impact impulse output for faster drilling with high speed at 1000 RPM. BulletPoint9 : Ergonomic design and anti-vibration handles for hand or rig guided drilling.
