Large Countersink – Surgical Hand Drill – 11-1631-00

4.5 mm and 6.5 diam Screws Tip 4.5 mm
When fixation hardware moves into larger diameters, the countersink must be selected accordingly. Article 11-1631-00 is the Large Countersink pattern, specified for 4.5 mm and 6.5 mm diameter screws and identified with a 4.5 mm tip specification.
Its position within the countersink range makes it useful for orthopedic trays that need a dedicated option for larger fixation systems. Rather than using a smaller instrument outside its intended size range, the surgical team can select a countersink that corresponds to the listed screw diameters.
• Large Countersink pattern for larger fixation hardware.
• Listed for 4.5 mm and 6.5 mm diameter screws.
• 4.5 mm tip specification.
• Suitable addition to fixation sets containing compatible screw systems.
Countersinking prepares the area around the drilled hole so the screw head can sit appropriately within the prepared surface. The step can be particularly relevant when the fixation construct requires the screw head to be accommodated without leaving an unnecessarily prominent profile.
For a busy orthopedic service, having size-specific countersinks arranged with the corresponding drills and drivers makes tray setup easier to verify before a procedure. It also helps procurement teams identify replacement instruments without relying on appearance alone.
Article 11-1631-00 belongs naturally in a selection of bone surgery instruments intended for fracture fixation and related orthopedic procedures. Its listed screw range provides a straightforward way to distinguish this large pattern from the smaller countersinks in the collection. The larger format is especially relevant when the tray includes fixation systems that cannot be adequately represented by the smaller countersink patterns.
