The End Mill Bits are a great bit for plunging directly into the wood and pulling to the side. They can also be used to remove bulk material in a hurry. They cut incredibly fast and fairly clean. We have many people use these end mill bits for piercing into woodturnings. Their open flute design helps to prevent burning while allowing the user to maintain good control. These bits are also great for using in milling machines as well as the New Micro Motor Grip Guide. These are made from a high quality carbide metal and come in an 1/8" shank. Overall length is 1 1/2" with a cutting length of 1/2".
