Vouyar 18-Inch Forstner Extension with 3-8 Hex Shank - Deep Drilling Reach

Meet the Vouyar 18-Inch Forstner Extension, a purpose-built accessory designed to help you reach deep into cabinets, thick tabletops, and other hard-to-access spaces. The long length opens possibilities you might not attempt with standard bits, letting you bore precise holes without repositioning your project or tool.

Key design points that support your project flow

• Ultra Long Extension: 18-inch length to reach awkward corners and recesses, reducing the need to flip or rotate your workpiece.
• 3/8 hex shank compatibility: Works with Forstner bits that use a 3/8 shank and fits a range of rotary tools you already own.
• Secure fit: The two hex key screws lock the bit shank in place, lowering the risk of slippage during cuts. An included Allen key is provided for quick adjustments.

Durability and compatibility you can count on

Constructed from high carbon steel with a robust cast body, this extension balances strength with a lighter weight profile, so you can handle longer drilling sessions without fatigue. It’s designed to be compatible with most Forstner bits currently on the market, helping you upgrade your toolkit without a separate purchase from each brand.

• Durable: High carbon steel cast body offers solid structural strength for repeated use.
• Versatile: Designed to accept a wide range of Forstner bits, broadening your drilling options.

The end result is a tool that can help you tackle projects more efficiently, whether you're routing hinge recesses, crafting decorative inserts, or drilling deep pilot holes for complex joinery. While outcomes depend on many variables, the extension is positioned to support clean, controlled bit alignment, steady depth, and reliable engagement with your existing rotary tool setup.

Note: Always match the bit size and shank to your tool’s specifications and follow safety guidelines for best results. The Vouyar extension is a practical addition for woodworkers, hobbyists, and professionals who value reach, stability, and compatibility in a single accessory.

Benefits you might notice include easier access to deep drilling tasks, improved control in tight spaces, and the potential to complete deeper cuts in a single setup, reducing the need to reposition tools mid-project.
