Overview
The Cranial Trephines and Circular Saws page gives neuroscience and small-animal surgery labs a focused selection surface for cranial trephines and microdrill circular saws. The source-backed trephines use a 2.35 mm rod diameter, 26 mm rod length, and selectable 3.0 mm to 10.0 mm tip diameters for circular cranial openings, skull fenestration planning, and bone-window preparation. The circular saw options cover a 3-piece kit plus 7.0 mm, 10 mm, and 13 mm diameters for hard-tissue cutting workflows.
The buying value is diameter control around an existing cranial drill station. Trephines help labs choose the intended circular opening size before the procedure, while circular saws support cutting bone and other hard substances when a saw profile is more appropriate than a burr or standard drill bit. This page keeps the trephine and saw accessories separate from ConductScience microdrills, drill-bit bundles, and stereotaxic drill holders so the buyer can complete an existing station without duplicating the powered drill itself.
Scientific Use
Cranial trephines are used in small-animal neuroscience workflows where a controlled circular skull opening or bone window is part of the surgical preparation. Common planning contexts include cranial-window work, traumatic brain injury model preparation, skull fenestration before downstream access, and regeneration or reconstruction studies after bone removal. Literature examples also describe trephines driven by high-speed microdrills for cranial window preparation in mouse cortical imaging workflows.
Because trephine diameter determines the opening scale, the configuration choice should be made alongside the planned anatomical target, stereotaxic setup, drill holder, microscope access, anesthesia, warming, sterile preparation, and lab-approved surgical workflow. Use the circular saw variants when the station needs a saw-format accessory for hard-tissue cutting rather than a cylindrical trephine opening.
Buying Fit
Choose this page when the purchase is a cranial drill accessory set, replacement trephine, or saw diameter choice. Pair the selected variant with a compatible ConductScience microdrill, stereotaxic microdrill holder or cranial drill holder, drill-bit page, fine tweezers, bone instruments, retractors, magnification, anesthesia, warming, and sterile-field supplies selected around the procedure.

Practical Tips
Choose trephine diameter around the planned cranial opening size before selecting the rest of the drill-station accessories.
Why: The source-backed trephine range runs from 3.0 mm to 10.0 mm, so diameter is the main scientific and purchasing decision.
Review the selected accessory with the ConductScience microdrill, microdrill holder, cranial drill holder, and drill-bit options.
Why: Trephines and circular saws are accessory choices; the powered drill and positioning hardware determine how the station is completed.
Store trephines and saws by diameter in a protected holder or tray and inspect the cutting edges before scheduled work.
Why: Organized storage keeps the correct diameter available and helps preserve cutting performance for repeated cranial-access workflows.

Compliance
Which trephine diameters are available?
The page includes trephines with 3.0 mm, 3.5 mm, 4.0 mm, 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, and 10.0 mm tip diameters. The trephines are specified with 2.35 mm rod diameter and 26 mm rod length.
Which circular saw options are available?
The circular saw options include a 3-piece kit plus individual 7.0 mm, 10 mm, and 13 mm diameter saw configurations for compatible microdrill workflows.
How is this different from the Microdrill page?
This page is for the cutting accessories: trephines and circular saws. Use the Microdrill page for the powered drill, and add a stereotaxic microdrill holder or cranial drill holder when the workflow needs fixed positioning.
When should I choose a trephine instead of a circular saw?
Choose a trephine when the workflow is planned around a controlled circular opening diameter. Choose a circular saw when the station needs a saw-format accessory for cutting bone or other hard substances.
What should be ordered with this page for a complete cranial access setup?
A complete setup may include a compatible microdrill, stereotaxic microdrill holder or cranial drill holder, drill bits, fine tweezers, bone instruments, retractors, magnification, anesthesia, warming, and sterile-field supplies selected around the procedure.
