  • 【Exceptional Abrasion-proof Carbon Steel】Drill chuck extension adopted heat-treated 45# carbon steel, with significantly enhanced hardness and abrasion resistance. Tensile strength 1.5 - 2 times that of low-carbon steel; Heat resistance exceeding 200℃, far superior reliability and thermal stability to aluminum/copper alloys in heavy-duty scenarios. Smooth operation and long-lasting durability for demanding drilling tasks, backed by 45# carbon steel’s inherent strength and stability.
  • 【Double Sliproof Design】The hole saw extension built-in dual anti-slip hex screws for enhanced bit and drill jaw stability. 2 anti-slip hex screws delivers secure grip, zero wobble, and reduced torque loss—eliminating slippage issues of traditional extensions in hardwood applications. Includes two Allen keys for convenient adjustments. This greatly reduces the risk of safety accidents caused by drill bit falling off during operation.
