Counter Sink With T-Handle For Large Screws

Description

Counter Sink With T-Handle For Large Screws

The large screw countersink cuts a seat in bone so the screw head sits flush. Its T-handle gives steady hand control.

Why countersink

Without a seat, a screw head touches bone at one point. Therefore stress concentrates there and the cortex can crack. Additionally, a countersunk seat spreads the load evenly.

Size

The countersink is listed for 4.5 mm and 4.5 / 6.5 mm large screws. Check your screw system to confirm. Besides, we can help match it.

Who uses a large screw countersink

Trauma surgeons use it with lag screws placed outside a plate. It also suits malleolar and other large screws. Scrub staff keep it with the large fragment set.

Technique

Seat the cutter in the pilot hole and give the T-handle a few even turns. Furthermore, a shallow seat is all you need. Avoid cutting too deep.

T-handle control

The T-handle allows two-handed turning. Consequently, the cut stays even. Also, that gives a neat seat for the screw.
