Choosing between two very different ways to buy carbide end mills can feel like comparing a precision tool to a raw material. In the tooling cutters abrasives category, this head-to-head puts a 5-piece set of new SGS 12mm corner radius end mills against a 10 lb lot of used solid carbide end mills. The new set costs USD 229.00; the bulk lot costs USD 320.00. That puts the lower-priced option 28% below the higher-priced one.
Quick verdict
If you need a known cutter geometry for a machining job today, the SGS five-pack is the clear pick. If you need carbide mass for resharpening or scrap recycling, the 10 lb lot is the purpose-built choice.
Price and condition at a glance
| Option | Price | Condition | What you are buying |
|---|---|---|---|
| 10 lb solid carbide end mill lot | USD 320.00 | Used | Bulk carbide for recycling or resharpening |
| New SGS 12mm corner radius set | USD 229.00 | New | Five matched 6-flute solid carbide end mills |
Where each product wins
The SGS set wins on predictability. Every tool shares the same 12mm cutting diameter, 1.0mm corner radius, and six-flute design, so you can set up a job and repeat it across all five tools. That is valuable when tolerance matters and you do not want to spend time measuring each cutter.
The 10 lb lot wins on quantity and flexibility. Instead of buying five specific tools, you get a bundle of solid carbide end mills that can be ground back into usable shape or sold as carbide scrap. It is a pragmatic buy for a shop that does its own tool grinding or participates in carbide recycling.
Product notes
10 lbs solid carbide end mills for scrap recycling or resharpening
If your goal is material recovery, this USD 320.00 lot gives you 10 lbs of solid carbide end mills with no intent to use them as-is. The used condition is acceptable because the value is in the carbide itself. Resharpening operations can grind a new geometry into these tools, and recyclers will buy them by weight. The limitation is that you are not getting a matched set of identical end mills; the lot is a mix of worn tools, so it will not solve a specific machining requirement without extra work.
5 pcs) New SGS 12mm (0.4724") 1.0R Corner Radius 6FL Carbide End Mill S04607
For a machinist who needs a ready-to-run corner radius end mill, the SGS set at USD 229.00 is the more direct choice. You get five new solid carbide tools with a 12mm cutting diameter, 1.0mm corner radius, six flutes, and a 1/2-inch shank. The new condition means you can load a cutter and trust its specs. The limitation is that this set only covers one size and geometry; if your work calls for different diameters or radii, these five tools will not adapt.
Final choice by use case
Buy the 10 lb carbide lot if you treat carbide as material you can resharpen or recycle. Buy the SGS five-pack if you need a precise 12mm corner radius end mill right now. The SGS set is the lower price in this comparison, but the two purchases solve different problems.
