JNJonMan Extensions for power tools

1Crafted from a combination of chrome-molybdenum alloy steel and aircraft-grade aluminum, heat-treated for enhanced strength, these extensions offer 1200MPa compressive resistance and triple the wear durability. The 3/8″ quick-change interface fits drills and wrenches, while the knurled anti-slip surface ensures a secure grip. Ideal for heavy-duty tasks like construction demolition and equipment maintenance, they extend tool reach and working depth.
2.Featuring a telescopic design adjustable from 20 to 60cm and a built-in universal joint for multi-angle rotation, these bars access tight spaces with ease. Six conversion adapters ensure compatibility with drills, angle grinders, and more. The lightweight build and anti-slip rubber handle reduce fatigue during extended use, making them perfect for home renovations, pipe installations, and other versatile tasks.
3.Constructed from V0-grade flame-retardant epoxy resin with an insulation resistance of 10^12Ω and 10kV high-voltage certification, these extensions prevent electrical hazards. The fully rubber-coated surface offers both a secure grip and electric shock protection. Ideal for live electrical maintenance and equipment installation, they provide reliable safety for professional electricians.
4.Equipped with super-strong neodymium magnets generating 8kg of pulling force, these extensions securely pick up small parts like screws and nuts, preventing drops during overhead work. The 360° rotating head enables precise positioning in tight spaces. The food-grade plastic coating resists corrosion, making them ideal for delicate tasks such as appliance repair and automotive engine maintenance, enhancing both efficiency and safety.
5.Precision-machined by CNC with a concentricity error of less than 0.05mm, these extensions maintain stability during high-speed rotation. The hard chrome-plated surface offers over 5,000 hours of wear resistance. Micron-level adjustment devices enable precise positioning and depth control. Ideal for precision tasks like instrument assembly and mold processing, they meet the demanding requirements of professional work.
