When you're choosing raw materials metal stock and need a 12-inch round steel rod for a machining project, the real question is material grade and starting diameter. Two new listings square off: the Oakland Steel Inc. 12L14 bar and the oversized D2 tool-steel rod.
Quick verdict
The 12L14 Steel Bar Stock is the smaller-diameter rod for CNC lathe work. The D2 Tool Steel Round Rod is the larger oversize bar for tooling jobs that need extra stock. Pick based on whether your part is a machinable carbon-steel round or a tool-steel blank you'll machine down to size.

Where the 12L14 bar wins
The 12L14 listing comes from Oakland Steel Inc. and names a United States country of origin. The 12L14 grade is known for excellent machinability, and the bar is labeled for CNC lathe metalwork. If your job is turning a machinable round, this listing lines up with that task.
Where the D2 rod wins
The D2 rod is sold oversized, in annealed condition with a machined finish, and the stated tolerance leaves extra material on the diameter. That makes it the better fit when you want to start large and machine down to a clean final size in a tool-steel part.
Product notes
12L14 Steel Bar Stock
This is the Oakland Steel Inc. bar in the 12L14 grade, listed for CNC lathe metalwork. The grade is known for good machinability, and the listing shows a United States country of origin. The stated outside diameter is the smaller of the two bars, which is handy when you want a compact round blank but does mean less starting material for a cleanup pass than the larger D2 option.
D2 Tool Steel Round Rod
This is the D2 tool-steel rod, sold oversized so the bar carries extra material relative to the nominal 1-1/4-inch size. The annealed condition and machined finish make it a practical starting blank for tooling work. The trade-off is that the larger starting size means you have more material to remove if your finished part is much smaller, so it suits jobs where a bigger oversize blank is exactly what you need.
Final choice by use case
When you're turning a machinable part from a smaller round, the 12L14 Steel Bar Stock is the direct choice. When you're making a tool-steel part that benefits from an oversize D2 blank, the D2 Tool Steel Round Rod is the one to grab.
