Extension Reach and Shank
The Eagle Tool US ETX25036 is a 36 in drill bit extension with a 1/4 in shank diameter. It accepts hex-shank drill bits and extends their reach for deeper holes. The straight body features three flats that prevent slipping in a drill chuck. It suits tradespeople who need extra length without changing bits.
Behaviour Under Sustained Use
The straight, three-flat design keeps the bit centred during continuous drilling. Heat builds along the 36 in length during prolonged cycles, so periodic withdrawal clears chips and reduces binding. The extension transmits torque directly without a flexible joint, so lateral force must be minimised to avoid deflection.
Practical Limits of the Hex Interface
The 1/4 in hex shank limits maximum torque before the flats round out in the chuck. Long reach amplifies any run-out, so precision drops as depth increases. The extension is not suited for high-speed production drilling or materials that demand rigid, short tooling. Buyers who need a shorter or thicker-shanked extension should select a different model.

Questions about this item
Does the 36in length add noticeable vibration or heat when drilling all day?
The straight three-flat design keeps the bit secure in the chuck, reducing wobble that causes heat; no motor is present so the extension itself generates no heat.
What shank size must my drill chuck accept for the 1/4in shank to fit?
Your drill needs a chuck that opens to at least 1/4in to grip the hex shank with three flats.
Will the 36in extension work with my older 3/8in keyed chuck drill?
Only if that chuck can clamp a 1/4in hex shank; the three flats are made for keyless 1/4in-capable chucks.
