Dental drill surface treatment

A dental drill comprising

• a shaft extending along a central longitudinal axis from a proximal end to a distal end, the shaft comprising
• a shank at the proximal end of the shaft, the shank being adapted for connection to a rotary driver, and
• a fluted section distal of the shank, the fluted section comprising at least one flute extending along the longitudinal length of the fluted section, at least a portion of the fluted section of the shaft comprising a roughened acid etched and electro-polished surface with smoothed peaks and one or more visual marking,
• wherein the dental drill is produced according to a method comprising:
• acid etching at least the portion of the fluted section of the shaft in order to create a visible matted effect,
• subsequently electro-polishing at least the portion of the fluted section of the shaft in order to visibly reduce said matted effect, and
• subsequently creating the one or more visual marking within the portion of the fluted section of the shaft.
