| Pneumatic Drill | Utilizes air pressure to power the drill | Cranial drilling, accessing deeper brain structures | High speed, lightweight, effective for precise cuts | Requires a compressed air source, noise level can be high |
| Electric Drill | Powered by electricity, equipped with various attachments | Craniectomy, bone removal | Consistent power, various speed settings, versatile | May overheat, heavier than pneumatic drills |
| Battery-Operated Drill | Cordless drill that can be powered by rechargeable batteries | Emergency surgeries where mobility is crucial | Portable, no cords, easy to use in various settings | Battery life limitations, may have less power than corded options |
| Ultrasonic Drill | Uses ultrasonic vibrations to create precise cuts in tissue | Minimal invasive surgery, delicate brain tissues | Less trauma to surrounding tissues, fine control | Specialized equipment, can be expensive |
