Fulton 6-inch & 10-inch Forstner Bit Extension Set – Heavy-Duty Steel, 3/8-Inch Shank, Deep Hole Extensions

Extend Your Reach with Fulton Forstner Bit Extensions

The Fulton 6-inch and 10-inch Forstner Bit Extension Set is designed for projects that demand deeper, cleaner holes. Crafted from heavy-duty steel, these extensions pair with a precision-machined extension chuck to securely grip 3/8-inch shank Forstner bits, helping you bore deeper without sacrificing control. Ideal for woodturning, furniture making, and carpentry, this set enables flat-bottom holes and deep starters in a variety of timber species, from softwoods to hardwoods.

With a focus on precision and durability, the extensions maintain a tight fit between the bit and connector, supporting repeatable results across long workdays on the shop floor or job site. Use them with drill presses, lathes that have a drill chuck installed, or standard power drills to tackle vessels, pepper mills, salt shakers, or pass-throughs for wiring. While the Forstner bits themselves aren’t included, the extensions are designed to maximize the reach and stability of your existing bits.

Key Benefits and How They Help

• EXTENDED REACH: The 6-inch extension provides over five and a half inches of additional depth, while the 10-inch extension adds more than eight inches for deeper, cleaner bores.
• SECURE FIT: Precision-machined extension chucks accept 3/8-inch shank Forstner bits for minimal wobble and reliable alignment.
• HEAVY-DUTY STEEL: Built from durable steel for long-lasting performance under demanding woodworking tasks.
• VERSATILE APPLICATIONS: Perfect for deep holes needed in vessels, furniture components, and wiring routes through timber.
• COMPATIBLE TOOLS: Works with drill presses, lathes with chucks, and power drills; bits and machinery are not included.

Real-World Scenarios

Picture crafting a large pepper mill or a long, flat-bottom dowel cavity where standard Forstner bits don’t reach. These extensions help start and guide clean bores, reducing rework and improving alignment across grain patterns. Whether you’re building a cabinet feature, a turned vessel, or a structural pass-through, the Fulton extensions offer a practical upgrade to your current toolkit without forcing you to purchase new machinery.
