USING AN EDGE FINDER •The edges of a workpiece must be located before doing mill work that requires great accuracy. An edge finder helps in finding the edges. •800-1200 spindle RPM is recommended. •To use an edge finder, slightly offset the two halves so they wobble as they spin. •Slowly move the workpiece towards the edge finder.

Yes, this method requires a separate drilling tool to make the pilot hole, but, unlike the previous one, it will let you use non-center-cutting tools and improve the chip evacuation. Here is a neat trick to avoid chips from wrapping around your End Mill: shift your Pilot Hole in such a way, that the drilled hole is tangent to the circumference ...

The drill press use drill chucks to hold the drill bit and move it up and down with the help of a feed lever. The workpiece is held manually on the bed or it can be fastened with the help of a vice or clamps. One thing to be sure of is that the cutting tool moves only vertically when we talk about drill press.

Use carbide end mills for harder materials and high production applications. Sometimes extra length end mills are necessary to use, but to combat deflection (bending of the bit) operate at the proper speed and feed rates and always use the most rigid (shortest and widest) end mill available for the application.

Pilot Mill. Special mill that has a heavy tubular extension below it called a pilot or stinger. The pilot, smaller in diameter than the mill, is designed to go inside drill pipe or tubing that is lost in the hole. It guides the mill to the top of the pipe and centers it, thus preventing the mill from bypassing the pipe. Also called a piloted mill.
