Abstract: An exemplary method for optimizing drilling performance of a rotary drill tool is disclosed. According to the method, a rotary drill tool may be secured to an orienting member and a cutting element rotational axis of the rotary drill tool may be identified. Radial locations of a plurality of surface regions of the rotary drill tool may be measured relative to the cutting element rotational axis. At least one selected surface region from the plurality of measured surface regions may be modified such that the at least one selected surface region is located at a selected radial distance relative to the cutting element rotational axis. An exemplary method for grinding a down-hole drill tool is also disclosed. According to the method, a down-hole drill tool may be secured to a holding member in a substantially vertical orientation and portions of the down-hole drill tool may be ground using a grinding wheel.

Abstract: Disclosed are embodiments of systems, methods, and apparatus for the automated placement and removal of traffic channelizers, such as traffic barrels. Some embodiments include a traffic channelizer handler unit for removing a traffic channelizer from a roadway and for subsequent placement of the traffic channelizer on the roadway and a storage unit for receiving the traffic channelizer. The traffic channelizer handler unit may be configured to place the traffic channelizer in the storage unit during a load process and retrieve the traffic channelizer from the storage unit during an unload process.
