- 【Specification】 Overall Length: 16" (400mm); Effective Working Lengths: 14"(350mm); Connection: 1-1/4-7 UNC Thread; Extension Shape: Hexagon shank with 1.61‘’（41mm） wrench size (SW 41)
- 【Hexagonal Design】The hexagonal shank design, compared to the round design, prevents the shank from rotating in the chuck, allowing it to fit securely into the tool chuck and preventing slippage. In addition, the hexagonal shank can be used with different tools, particularly in applications requiring higher torque, as it is more effective at transmitting force than a round shank.
- 【42Cr4 Steel (DIN 1.7045) 】42Cr4 Steel (DIN 1.7045) is a German standard material used for manufacturing various hot forming tools, hot stamping dies, and tool steel. This material is characterized by high strength, excellent toughness, reliable hardenability and outstanding impact resistance. It is widely utilized in machinery, shafts, gear shafts, wheels and industrial tools.
- 【Widely Applicable】Core drill bit extensions make it easy to quickly assemble diamond core drill bits, allowing for deeper drilling into concrete, reinforced concrete, brick, block, and masonry.
- 【Note】It only works with 1 1/4-inch UNC threads. Please pay attention to the thread of the core drill bit. This adapter cannot be used in hammer mode.
