Choosing carbide end mills for your shop comes down to matching the tool to the material, the depth of cut, and the geometry your part needs. This guide compares four new 5-piece solid carbide sets in the tooling cutters and abrasives space, with listed prices from $49.99 to $229. You'll see which one fits a budget-minded hobbyist, which suits deeper 1/2" work, and which brings corner-radius capability from a US-made Kyocera SGS set.
Quick take
All four sets are new and made of solid carbide. The 1/4" ZIMI set is the entry-point price in this group. The 1/2" ZIMI set offers a 1.377" length of cut for deeper work. The Kyocera SGS 12mm corner radius set is the higher-priced pick for corner-radius profiling. The other 1/2" ZIMI listing, at a higher price, carries the same nominal specs with 'NEW!' in the title.

Decision matrix
- Choose the 1/4" ZIMI set for small-diameter work on a budget.
- Choose the 1/2" ZIMI set when you need a 1/2" shank and a 1.377" length of cut.
- Choose the Kyocera SGS 12mm set if you need a 1.0R corner radius.
- Consider the 'NEW!' 1/2" ZIMI set if the title label matters more to you than the price gap.
Product notes
SGS 12mm Corner Radius End Mill Set (5 pcs)
This is the only corner-radius option here, with a 1.0mm radius on each flute and a 6-flute solid carbide body. It comes from Kyocera SGS, is made in the United States, and the set includes five pieces. The TA coating and 12mm cutting diameter make it a fit for profiling work where you want a rounded edge rather than a sharp square corner. The trade-off is that this listing sits at the top of the price spread. It also uses a 12mm / 0.4724" cutting diameter, so it is not a true 1/2" square end mill if square-shoulder cuts are what you need.
5PCS 1/2" 4 FLUTE LONG CARBIDE END MILL - TiALN COATED
This ZIMI set gives you five TiALN-coated 1/2" solid carbide end mills with a 1.377" length of cut, which suits deeper passes on alloy and hardened steel. The set is made in China. Compared with the 1/4" set, this one costs more, but you get a longer cutting section and the larger shank diameter. The main thing to keep in mind is that the 1/2" size may be more tool than you need if you're doing small, detailed work. There's also another 1/2" ZIMI listing in this guide that carries a higher listed price, so check the listed prices side by side.
5PCS 1/4" 4 FLUTE LONG CARBIDE END MILL - TiALN COATED
At the low end of the price spread, this is the most affordable set in the comparison. It's a five-piece 1/4" TiALN-coated carbide set with a 0.708" length of cut, and the description points to shallow-groove and profile milling as well as precision machining. The 4-slot design gives good rigidity for smaller workpieces. The limitation is the shorter cutting length: if you need to make deeper passes, the 1/2" sets offer roughly twice the length of cut. For a first set or for finishing small parts, the lower price makes it an easy pick.
NEW! ! 5PCS 1/2" 4 FLUTE LONG CARBIDE END MILL - TiALN COATED
This listing shares the same nominal specs as the other 1/2" ZIMI set: five TiALN-coated solid carbide end mills, 1/2" shank, and a 1.377" length of cut. The difference is the 'NEW!' label in the title and a listed price above the other 1/2" set. If you want this specific listing, you'll pay more than the other 1/2" ZIMI set. The specs don't show any extra features in the title or description, so the extra cost is tied to the listing itself rather than a different tool configuration.
Final recommendation by use case
- For small-diameter work and the lowest listed price, the 1/4" ZIMI set is the most direct choice.
- For a 1/2" shank with a longer cutting length, the standard 1/2" ZIMI set delivers the specs without the extra cost of the 'NEW!' listing.
- For corner-radius profiling in a 12mm size, the Kyocera SGS set is the one to budget for.
