Measurement drill bit
The broken line showing of a measurement drill bit is for the purpose of illustrating environmental structure and forms no part of the claimed design.
The claimed measurement drill bit is used for grinding, buffing, or boring. The lines of contrasting light, and dark, give the user the ability to measure distance, and/or depth, while rotary tool is in motion. The lines make small measurements possible while in contact/boring with different materials.
