10-Inch Alloy Steel Forstner Bit Extension – Fits 3/8" Shanks, Adds 8" Depth, With Wrench & Nuts

About This Product

Ever run into a situation where your standard Forstner bit just isn't long enough to reach that deep flat-bottom hole?

This 10-inch alloy steel extension is exactly what you need.

It adds about 8 inches of extra reach, so you can drill deep holes or flat-bottom cavities that regular bits can't touch.

The chuck outer diameter is 25/32 inch, and it works with any 3/8-inch round or hex shank Forstner bit.
The alloy steel build is super tough – no bending under pressure, even in hard woods.

Comes with two fixing nuts and a hex wrench to lock everything tight.
The nuts are high-quality too, so they don't loosen up while you're working.

Great for furniture makers, carpenters, and construction guys who need that extra depth without buying a whole new set of long bits.
Simple, sturdy, and effective.
