Using this extension our team found that it was a great addition to our industrial drill bits collection .The length of the extension was perfect for reaching deeper targets without having to constantly move the drill. the extension was also very sturdy and durable, which is important WHEN dealing with tough industrial jobs. The only downside is that it can be a bit heavy to handle for prolonged periods of time. Overall, we highly recommend this product for anyone in the Industrial and Scientific field looking for a reliable extension..
