Overview

Meet the ASNOMY 2-Piece Extra Long Forstner Drill Bit Extensions, crafted to add substantial depth to your Forstner bits with a 3/8 inch shank. Precision machined from high-carbon steel and finished for a smooth, polished feel, these extensions are built to pair with your existing drill setup while helping you tackle deeper pockets and more complex cuts in hardwoods and plywood alike.

What you get and how it fits

The kit includes two extensions: a 4.5 inch piece and a 7 inch piece. Each one extends the bit shank by 3-1/4 inches and 5-3/4 inches respectively, giving you reach for flat-bottom holes or start-depth projects such as vessels, containers, or deeper furniture elements. The inner diameter of the collet is 3/8 inch (9.7 mm), designed to accommodate 3/8 inch shanks or slightly smaller ones with a tight, wobble-free fit.

Key benefits and specs

  • Two total lengths: 4.5 inches and 7 inches for flexible depth options
  • Extend lengths of 3-1/4 inches and 5-3/4 inches to reach deeper pockets
  • Collet compatibility: 3/8 inch for secure mounting on standard bits
  • High-carbon steel construction, precision ground and polished for durability
  • Includes two set screws and hex key for quick, secure attachment

How to use

  • Attach the extension to the Forstner bit shank and align with the 3/8 inch collet
  • Use the included hex key to tighten the screws for a stable fit
  • Proceed with drilling, maintaining steady feed and a clean drill path
  • Switch between extensions as your project depth requires without swapping bits

Why choose ASNOMY

These extensions blend durability with practical versatility, offering extra reach without requiring a new bit setup. The combination of tight tolerance, a polished finish, and included hardware makes them a convenient upgrade for projects that demand deeper, cleaner holes. While performance can vary by material and drill technique, the extensions are designed to be a reliable addition to a standard Forstner toolkit.
