12 in Drill Extension

The Eazypower Corp 88439 drill extension adds 12 inches of reach to standard wood drills. It features a straight shank with three flats for a secure grip in drill chucks. This accessory is intended for tradespeople and DIY users who need deeper access in woodworking tasks.

Build integration

The straight shank fits directly into a standard drill chuck without adapters. It frees up workspace by allowing the motor to stay clear of deep cavities or overhead joists. The three-flat design prevents slippage under load so the bit stays centred during extended drilling.

Thermals noise power

The extension has no moving parts and draws no power of its own. It adds negligible rotational mass so the drill runs at normal speed and temperature. Noise and vibration remain consistent with the drill and bit combination in use.
