Efficiency and simplicity: The core of this product is the special holder that is attached directly to the tailstock of your lathe. The holder contains a double bearing that is specifically designed to take forward and side loads. The bearings can withstand up to 948 kilos, making them the strongest on the market. This makes the product one of the highest quality and most stable drives on the market. While cheaper versions break quickly, this live drive can withstand large and unbalanced workpieces and a lot of pressure. Thanks to a practical inner taper, you can easily use different attachments. The taper fits perfectly with the attachments, which means that the drives run 100% smoothly. The drives can be separated from the holder using the ejector rod included in the set. Robustness and durability: The live center drive is made entirely of hardened steel, making it particularly resistant to impacts and daily wear and tear. A durable product you can rely on. The additional zinc alloy protects the product and makes it even more durable. Maximum hold: The multi-tooth ring of the star drive offers numerous advantages. The generous contact surface of the individual teeth ensures that they provide optimal grip once they have pressed into the wood. This secures your workpiece during turning and minimizes the risk of slipping. The combination of multi-tooth ring and spring-loaded centering point ensures the best power transmission during turning without tearing out the contact surfaces or splitting the wood. Whether you are an experienced woodturner or a newbie to the craft, the HOPE Live Star Drive Center from Hope Woodturning will delight you with its ease of use, efficiency and reliability.
