PCT introduces its 363-series end mill for machining aluminum. This tool’s design is based on the 360-series tool but modified specifically for roughing applications. The end mill has a three-flute design, with variable flute spacing (pitch) and variable helix. The company says its chipbreaker technology facilitates more aggressive speeds and feeds., while variable geometry helps reduce chatter. Meanwhile, an exclusive radial primary edge grind helps to prevent chipping on initial contact with the part. This tool comes with PCT’s Z-Power coating and has the option to be upgraded to the Exxtral carbon coating, which is said to increase performance 300-400 percent over standard PVD. 


  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • Threading On A Lathe

    The right choices in tooling and technique can optimize the thread turning process.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
