About this item

  • General Usage: Applicable with copper, copper alloys, cast iron, steels, carbon steels, alloy steels, pre-hardened steels, hardened steels, and stainless steel materials. Best use for materials HRC less than 50.
  • Solide Carbide: The material is European origin ultra fine grain carbide. We use the highest quality tungsten carbide powders and adjust the ratio of tungsten carbide and cobalt to meet the ideal hardness. It is stable and has excellent wear-resistance of the material. It significantly enhances the tool's lifespan and keeps the end mill sharp. It also helps keep the surface quality of your work-piece at the best level possible.
  • AlTiN Coating: It is a strong coating that's coated at temperatures between 450°C to 475°C. It is able to provide high wear resistance, lubricity, exceptional oxidation resistance, extreme hardness, and excellent abrasive wear resistance. It has higher reliability in dry operations, heat resistance, hard machining, and the resistance can be reduced.
  • 4 Flute Cutter: It has uniqe geometry and strong cutting edge. 4 flute is great for speedy cutting. Ideal for planar, step, groove, forming surface while the 45 degree helix design can perform smooth surface finish, better chip removal control than those with lower helix degree.

I bought these because I broke a drill bit off while drilling out a seized bolt and they cut exceptionally fast I did break a couple of these bits but it was due to using them in a drill and a slight sideways bind not the fault of the end mills just operator error would definitely buy these again

I was a tad skeptical as I had to drill some holes in hardened D2, this checks out at 58-60 on the Rockwell C scale. Pretty tough stuff. I had broken a good carbide ball end mill as that was what I had on hand. I've always had better results using a flat bottom end mill to drill small holes in hardened tool steel. I Only used one of these end mills (came in a 5 pack) to drill 3 o holes thru 3/16" D2. After use the corners were still sharp and none the worse for wear.

For cheap end mills the work fine. The key is slow and steady, and use cutting oil. I broke one flute off the first but after doing 4 key ways. Still works but plung cuts are off. Milling on a drill press isn’t ideal but they work.

Broke one already, probably my fault. Do seem to cut ok once you get going.
