Extension Set Overview

This Buhobha set supplies four magnetic bit holders with 1/4-inch hex shanks in 2, 4, 6 and 12-inch lengths. The chrome vanadium steel construction handles high torque from impact drivers and standard drills. A one-piece design transfers force efficiently while the double-lock collar secures bits firmly during use.

Ideal Users and Limits

The kit suits mechanics, electricians and DIYers who regularly drive fasteners in deep cavities or behind obstacles. The magnetic collar and quick-release sleeve speed up bit changes on the job. Buyers needing non-magnetic holders, SDS-plus shanks or lengths beyond 12 inches should look elsewhere.

Capacity and Reach

Four extensions cover most overhead, cabinet and automotive clearance challenges without stacking adapters. The 12-inch rod reaches deep engine bays while the 2-inch stubby fits tight corners. Cr-V steel resists rounding under heavy impact loads, though extremely high-torque industrial applications may demand specialised tooling.

Questions about this item

What driver or drill chuck do I need to fit the 1/4" hex shank on these extensions?

Any drill, impact driver, or screwdriver with a standard 1/4" hex chuck will accept the shank directly.

Will the magnetic collar hold bits securely when I use the 12" extension with an impact driver?

The double-lock magnetic collar is designed to grip bits firmly under high torque, reducing wobble even on the longest rod.

How can I verify the quick-release mechanism is engaging properly after I insert a bit?

Pull the collar back, insert the bit until it clicks, release the collar, then tug the bit — it should not come free.
