• 【Enhance Drilling Depth】 Our Forstner bit extension allows you to extend any Forstner bit shank by an additional 3-1/4 inches and 5-3/4 inches, making it ideal for deep hole turning projects on larger vases or containers. With simple installation, users can easily drill flat-bottom holes.
• 【Materials】 Constructed from high-carbon steel, featuring precision-ground surfaces for higher engineering quality. The collet has an inner diameter of 3/8 inches, allowing it to tightly secure and fit Forstner bits of the same diameter or smaller, avoiding noise and unnecessary vibrations, ensuring stability during operation.
• 【Easy Installation】 Each set includes two extensions (3-1/4 inches and 5-3/4 inches), along with a hex key and two set screws for securing the bit. Users can quickly install them and start working. It’s essential to tighten the set screws before using the bits to effectively prevent slippage at high speeds, ensuring safety and smooth operation.
• 【Anti-Slip Design】 This extension features an innovative anti-slip design at the connection point, which addresses the common slipping issues found in traditional Forstner extensions. This ensures a secure grip when drilling hardwood, significantly enhancing stability during operation.
• 【Convenient and Practical】 This kit is including two Forstner bit extensions of varying lengths along with the necessary tools. It caters to DIY enthusiasts and professional woodworkers alike, providing more drilling options that are both convenient and practical.
