The 2 inch SAE and metric Ball-End Hex 20pc Mega Bitrail is for the access problems that need two things at once: angle and reach. The ball-end tip helps when the bit cannot line up straight with the fastener, and the 2 inch length helps when the fastener sits deeper in the work area or behind surrounding components.

That combination makes this set useful on equipment, vehicles, machinery, and other assemblies where hex fasteners are not always placed with tool access in mind. Railer keeps both SAE and metric sizes on one mega bitrail, which helps users move across different hardware standards without breaking up the kit.

Compared with the 1 inch version, this set is the better choice when depth is part of the problem. It stays organized like the rest of the Bitbitrail system, but it gives you a little more room to work when standard reach is not enough.

What sizes are included in this comprehensive ball end hex bit set?

This massive 20-piece set includes a complete range of both fractional (SAE) and Metric (MM) hex sizes. The SAE sizes range from 5/64" to 5/16", and the Metric sizes range from 2mm to 10mm.

What is the advantage of a "ball end" hex bit?

The ball end design allows you to engage the fastener at an angle (up to 25 degrees). This is incredibly useful for driving and extracting screws in tight, obstructed, or awkward spaces where a straight-on approach isn't possible.

Why choose a 2-inch screwdriver bit?

The standard 2-inch length provides an ideal balance of compact size and direct power transfer. It allows the bit to lock directly into impact driver chucks without needing a separate magnetic bit holder, offering a sturdy, low-wobble connection.

How does the Mega Magnetizer Bitrail work?

The premium Mega Magnetizer Bitrail holds all 20 bits securely and serves as a magnetic charger. Sliding your bits into the rail magnetizes the steel, which helps the bit tip securely grip fasteners during installation, reducing drops and saving time.

Are these bits impact-rated for heavy-duty use?

Yes. These 2-inch ball end hex driver bits feature a standard 1/4-inch hex shank and are precision-machined to withstand the high-torque demands of modern cordless impact drivers and power drills.

• Impact Drivers: Fully compatible with all major brand 1/4-inch quick-release impact driver chucks and collets.
