More features

• Safety: Two hexagonal screws firmly fix the handle, effectively reducing torque loss. Compatible with most hexagonal-head drill bits on the market.
• The tool requires high-quality materials: Our extension shaft is made of sturdy high-carbon steel to ensure structural integrity, and its surface is precision ground and polished.
• Hexagonal handle diameter: 3/8 inch. Total length: 18 inches. Extension length: 16.25 inches. It can drill flat-bottom holes using standard Fosterner drill bits and can also be used for projects such as deep hole turning on larger vases or containers.
• Note: The inner diameter of our Fosterner drill bit extension chuck is 3/8 inch, so it is only suitable for Fosterner drill bits of 3/8 inch or smaller specifications. Before use, please tighten the screws to prevent slippage during high-speed rotation.
• Extra-long 18-inch Fosterner drill bit, helping you drill fine holes in hard-to-reach corners of the project.
