NES-3512

4.0 mm
At 4.0mm, the NES-3512 sits solidly in the wider half of this bone splitting chisel range, built for ridge-splitting cases where the bone can comfortably accommodate a broader instrument from the outset, or where a split has already been started with a narrower blade and now needs expanding.
Wider chisels like this one tend to cover more ground per pass, which matters when working efficiently along a longer ridge segment. Rather than repeating multiple narrow passes, a 4.0mm blade can achieve the necessary separation in fewer motions, provided the bone density and thickness support that approach.
That efficiency doesn’t come at the cost of precision. This chisel shares the same carefully maintained edge geometry as the narrower sizes in the lineup, so practitioners moving up in width aren’t sacrificing the control that makes ridge splitting predictable and safe.
Among the maxillofacial surgery instruments supporting implant site development, a 4.0mm chisel like this one is often reached for once initial splitting has established the direction, letting the practitioner widen the separation with confidence.
Built from surgical-grade stainless steel, this chisel withstands the mechanical stress of repeated mallet contact and standard sterilization protocols, holding its precise edge reliably over years of demanding clinical use.
