A set of dental drills comprising:

• two or more dental drills, and a drill guide having an inner diameter and a lateral slot, each of the dental drills comprising
• a cutting portion that has an end-face drilling end at one end of the dental drill, and
• a shank portion that has
• a receiving region at an opposing end of the dental drill, the receiving region configured to be received in a drill holding device,
• a substantially circular-cylindrical guide region having a diameter that is matched to the inner diameter of the drill guide;
• the guide region configured to guide the dental drill within the matching inner diameter of the drill guide during a drilling process, and
• an insertion region configured to laterally insert the dental drill into the lateral slot of the drill guide and secure the guide region of the dental drill within the inner diameter of the drill guide, wherein the lateral slot of the drill guide is at least as broad as the insertion region;
• and wherein
• the guide region has a wider diameter than the receiving region and the insertion region,
• the guide regions of the two or more dental drills have the same diameter, and
• a maximum diameter of the insertion region is smaller than a maximum diameter of the guide region and a maximum diameter of the cutting portion of the dental drill.
