Buying problem
The trouble with raw materials metal stock for a CNC lathe is having the right diameter when you need it. Individual bars are fine when you know the job ahead of time, but setup tests and small runs often call for several sizes. The 12L14 Steel Round Bar Stock Assortment - 10 Pcs - CNC Lathe Machining Metal Rods takes the opposite approach: it gives you ten bars in a single order.
Quick verdict
This Oakland Steel Inc. 10-piece set is priced at USD 50.72. The bars are AISI 12L14, a resulfurized and rephosphorized carbon steel described as a strong choice for machining. The five diameters span 0.500 to 1.000 inch, giving a small shop a practical spread of round stock for many small turned parts. The mechanical profile points to machinability rather than heavy structural duty.
Who it suits
Machinists turning bushings, hose fittings, spindles, or other high-speed screw machine components will appreciate the range. Because the bars are round and come in common fractional sizes, they fit the kind of job that moves between different bar diameters without a lot of extra procurement. It is a stock pack for shops that want 12L14 available when a short run needs several sizes.
What stands out
Two bars of every included diameter mean you can test how the material cuts at one size, then move to the next paired bar without leaving the 12L14 family. The mechanical specs-Rockwell hardness B84, tensile strength 78,300 psi, yield strength 60,200 psi, and 10% elongation-reinforce the machining-grade character of this steel. It is not trying to be the toughest steel in the rack; it is trying to be predictable under the cutter.
Meaningful trade-offs
The 12-inch length and the fixed per-size count are the main constraints. If you need a bar longer than 12 inches or need more than two bars of a single diameter, this assortment will not stretch. The $50.72 price is for the whole set, so the value depends on how many of the included diameters you actually put to work. If only one size fits your jobs, you are paying for variety you may not use.
Bottom line
Get the 12L14 Steel Round Bar Stock Assortment if your work regularly cycles through 1/2-inch to 1-inch round stock and you like having multiple diameters ready at the lathe. It is a clean way to bring in 12L14 for small machining projects without assembling your own mixed order. Skip it if you already know your part sizes and need longer or more numerous bars of one diameter.

The reason to choose this set is the practical spread: five common diameters in one 12L14 purchase. The limitation is the format: 12-inch bars with a fixed number per size, so high-volume or long-part work will need additional stock elsewhere.
