1/4" Carbide End Mill, Extra Long, 4 Flute Solid Carbide Square End Mill, 4" Overall Length, Single End, Helix Angle: 30°, AlTiN Coated,1/4" Cutting Diameter,1-1/2" Length of Cut

This 1/2" carbide end mill work very well using an upright drill press to remove rivets tops from a ring gear.

I've abused this thing on my small mill and has lasted a surpringly long time for someone whose just learning what they're doing, going from aluminum to steel, to milling through welds

Works as described by manufacturer on hard alloy materials. Very satisified with the purchase.

Works real good. comes in a good container

Why did you pick this product vs others?: I needed a longer but Aluminum cutting: Worked flawless

Great for the milling I am doing.

Good sharpness and durability.

I ordered this 1/2" end mill for hobby use with my benchtop milling machine. It arrived well-packaged in its own plastic case and has the appearance of a high-quality tool. The cutting edges are very sharp to the touch. I took a few test cuts in a piece of 1/2" thick 6061 aluminum with good results. I've found that conventional milling with a little WD-40 gives me the best surface finish. I also use a steady blast of air to get chips out of the way and keep my cutting edges clean. Without the air I've noticed the cutters tend to re-cut some of the chips, leading to a smearing effect that dulls the finish. I didn't test this end mill on steel but I've used enough of these tools to know it should perform great. In past tests I've found aluminum to be a better indicator of surface finishes than steel, even though the carbide handles both materials without any problem. For my use in the hobby shop this seems like a great tool so far. Overall I'm very pleased with it.
