About this item

  • HIGH PROCESSING EFFICIENCY: the edge of end mill bits is HARD and SHARP with TIAIN coating, process the heat treatment materials under 32°with high speed, reduce changing times and improve the production efficiency.
  • APPLICATION: end mill bits are suitable for side milling, end milling, finish machining, etc. Apply to carbon steel, alloy steel, die steel, tool steel, cast iron, titanium, aluminum, etc.
  • CUTTING EDGE DESIGN: the bottom of end mill bits is u-shaped groove design, large front angle effectively reduces cutting resistance, sharp and durable, convenient for chip removal, further improve machining efficiency.
  • STRONG and DURABLE:The end mill bits are made from Ultra-fine tungsten steel bar, with high bending resistance and abrasion resistance, exclusive to HIGH HARDNESS, HIGH SPEED CUTTING applications.
  • Package Content : 2 x 1/4 inch End Mill

I used these today on aluminum and the performance was great. Brass is next. I won't be using them on steel. Good value for aluminum. We shall see about brass. For the price and delivery its a deal.

Very good endmills . They are accurate and good sharp cutters. If! I need any other sizes, I will be back.

I only used them to plunge cut on a drill press, but they seem to work well. They were very sharp and came in individual plastic boxes, nice touch.

These end mills seem quite good for the price. I have not yet tested them for physical properties. I don't expect them to cut AR500 plate, but for mild steel and plastics, they should be okay. Stainless is always problematic with HSS tooling, but I expect on 304L these will work without issue, tool life is the question.

The bit seemed to do its job, but after less than a minute of use, the aluminum we were milling melted to the bit, basically making it useless. My suggestion would be to use this bit in short durations and possibly use a cooling agent.
