This Product Selection Guide contains information to help select products in the Drill Bitts, End Mills category on DigiKey.com
The cutting tool products within this family are primarily intended for the production of printed circuit boards by means of a mechanical milling process, though those tools adapted for drilling holes do so equally well on boards that have been chemically etched. Characteristic of this application is a relatively small tool size in comparison to those commonly found in household or industrial use.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Diameter - Bit: Nominal diameter of the tool’s cutting circle; the size of the hole the bit makes.
Diameter - Shank: Diameter of the bit’s gripping/toolholding surface.
Material: Indicates the material composition of the device.
Number of Flutes: The number of separate channels cut into the drill bit to allow waste material to exit the drill-out.
Flute Radius:
Length - Flute: The length of the fluted portion of the bit, measured linearly from the front of the flute cut to the rear.
