Description of 🐍 Cobra Carbide 27304 Hi Performance Diameter: Unleash the Power!

Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Titanium aluminum nitride coatings become self-lubricating when used at very high speeds, making them ideal for cutting without coolant ("dry machining"). Round shanks allow use with a wide variety of toolholding systems. Suitable for profiling operation. High shear geometry with edge strength.

These are high quality end mills. I first tested this end mill on aluminum and it cut very well. I was able to increase the feed by 75 percent. Then I switched to 1018 steel and it cut like clockwork. Holds sharp edges very well. Would definitely recommend to anyone looking for quality carbide end mills for steel.

Pros
  • Milling Accessory
Cons
  • Crumpled Packaging

This nozzle also works very well as a dilator.

This End Mill is AMAZING. I taught myself how to cut steel with a drill press converted to an end mill. I made many mistakes and even damaged part of the cut surface, but it just keeps working. You won't believe the amount of abuse I've taken on this jet even when it's binding and jamming at 3000rpm, but it continues to work. The use of coolant increases the service life at high speeds. This nozzle also works very well as a dilator.

Pros
  • Cutting Tools
Cons
  • Long Lead Time

NOT FOR CHAPEOCO 3! NOT AS SHOWN!

Oh my god. So let's start by saying that the "60 degree spiral" doesn't look like the picture at all. It's not 60 degrees horizontal, it's 60 degrees vertical, so instead of the router shown in the photo, you're getting this thing that looks more like a lead screw on a 3D printer than a consumer CNC end mill. And while this is probably normal for most CNCs, it's a big problem for Shapeoko. On the first cut, when the drill moved about 60% of what I normally use with the trusted 4-blade 30-degree

Pros
  • Square Nose
Cons
  • Ugly Packaging
