About Extended Universal Trephine Kit
The Extended Universal Trephine Kit brings eight trephines into one cassette with the drills, expansion and compression screws, punches and drivers listed below. The trephines run from 2/3 mm to 9/10 mm, stated as inner/outer diameter. They sit alongside 16 conical drills with stopper codes, seven titanium-coated drills, three drivers, a torque-marked wrench and a depth gauge. Compared with a trephine-only kit, the difference is scope: one cassette holds the trephine range together with its supporting instruments.

Stainless-steel components are AISI 420, and the instruments are reusable. Reprocess the kit under the processing instructions supplied with it, within the limits those instructions set.
Eight trephines, two diameters each
A trephine is hollow. It cuts a ring and leaves a central core, which is why every size here carries two figures: the inner diameter first, then the outer. When comparing these with trephines you already stock, check both figures. For example, the 2/3 mm trephine has a 2 mm inner and a 3 mm outer diameter.
- 2 mm inner / 3 mm outer
- 3 mm inner / 4 mm outer
- 4 mm inner / 5 mm outer
- 5 mm inner / 6 mm outer
- 6 mm inner / 7 mm outer
- 7 mm inner / 8 mm outer
- 8 mm inner / 9 mm outer
- 9 mm inner / 10 mm outer
The conical and titanium-coated drills are separate, solid cutting instruments with their own labelling, set out below.
Drill labels and stopper codes
Conical drills. The S code refers to stopper length:
- 1.8/2.2 mm: S1, S3, S5, S7
- 2.2/2.7 mm: S1, S3, S5, S7
- 2.3/3.3 mm: S1, S3, S5, S7
- 2.8/4.5 mm: S1, S3, S5, S7
Titanium-coated drills, each marked L18.50:
- 2, 2.8, 3.65, 4.2, 4.5, 4.8 and 5.2 mm
The size label, the stopper code and the working length set by your protocol are three separate attributes. Use your protocol and the instructions supplied with the kit to establish how the stopper codes relate to drilling depth.
Matching the kit to your system
Compare assortments by component group and by interface rather than by headline piece count. In this kit, “Universal” describes the breadth of the assortment, and fit is decided interface by interface: the drill shanks against your handpiece, and the drivers against the implant system you place. The 6.35 mm wrench carries a 10–40 Ncm marking, which describes the tool itself.
When you request a quote, include:
- Number of kits
- Implant system and handpiece in use
- Any trephine or drill size you want confirmed against the lists above
- Packaging and documentation requirements
