Choosing tooling cutters abrasives starts with fit, not simply the lowest total: a 1/8-inch square end mill addresses a different requirement than a 3/8-inch stub-length cutter or a 1/2-inch configuration. The four choices here span USD 34.59 to USD 379, with two 1/8-inch selections alongside larger-diameter alternatives. Match cutting diameter, length of cut, shank, end type, and stated finish first, then use price to narrow an already compatible group.
Quick take
- The two 1/8-inch selections are the closest dimensional comparison: both state four flutes, a 1/2-inch length of cut, and a 1-1/2-inch overall length.
- The 3/8-inch ONLINECARBIDE pack is the stated stub-length choice, while CME's 1/2-inch configuration is the largest cutting diameter in this group.
- P1, P3, and P4 state United States manufacture; P1 and P3 also state United States origin.
- P3 is the only selection here explicitly described with no coating and a bright finish.

Product notes
5 Pack 3/8" Solid Carbide End Mills - 4 Flute Stub Length TiAlN Coated USA
S4e1e-YPSM's ONLINECARBIDE pack is the clear match when the required dimensions are a 3/8-inch cutting diameter and shank, a 5/8-inch length of cut, and a 2-inch overall length. The stated four-flute, center-cutting geometry and stub-length format give this pack a specific role rather than making it a substitute for the smaller 1/8-inch selections. It is also identified as solid carbide and made in the United States. Its limitation is cost: at USD 147.95, it sits above both 1/8-inch packs in the comparison.
1/8" Solid Carbide End Mills TiAlN Coated 4 Flute 1/2" LOC 1-1/2" OAL 10PCS
Choose this compact cutter when a 1/8-inch cutting diameter and shank are the needed dimensions and a square, single-end form is appropriate. It states four flutes, a 30-degree helix, a 1/2-inch length of cut, and a 1-1/2-inch overall length, making its basic geometry easy to line up with a small-diameter requirement. It is identified as solid carbide and China origin. The limitation is fit rather than format: its 1/8-inch dimensions are not interchangeable with the larger-diameter P1 or P4 selections. It has the lowest listed price in this group.
5 Pack 1/8" Solid Carbide End Mills - 4 Flute Center Cutting CNC USA Made
S4e1e-YPSM's ONLINECARBIDE 1/8-inch pack is a natural alternative when the desired specification is four-flute, center-cutting solid carbide with a 1/2-inch length of cut and 1-1/2-inch overall length. Both manufacture and origin are stated as United States, and the description calls out a bright finish. This pack is listed without a coating, which is a useful defining detail for shoppers specifically seeking that presentation. The limitation is that its 1/8-inch cutting diameter confines it to the smaller size class here; it does not replace the 3/8-inch or 1/2-inch choices.
10pcs 1/2"x1-1/4x3 Solid Carbide End Mills Tialn Coated,4flt,center-cutting-new
The CME pack is the selection to target when the 1/2"x1-1/4x3 title configuration is the requirement. Its title identifies solid carbide construction, TiAlN coating, four flutes, and center-cutting design, while the attributes state United States manufacture and a CME brand designation. It is also the sole 1/2-inch cutting-diameter choice among these four packs, separating it clearly from the 1/8-inch and 3/8-inch alternatives. The limitation is its USD 379 listed price, which is the highest in the comparison and should be weighed against the need for this specific larger configuration.
Final recommendation by use case
Pick the 1/8" Solid Carbide End Mills TiAlN Coated 4 Flute 1/2" LOC 1-1/2" OAL 10PCS when the lowest listed price is the deciding factor and its square single-end geometry fits. Choose the bright-finish ONLINECARBIDE 1/8-inch pack for its explicitly no-coating presentation. Move to the 3/8-inch ONLINECARBIDE pack for the stated stub-length dimensions, and select the CME pack when the 1/2"x1-1/4x3 configuration is essential. In this range, dimensional match should lead the decision.
