NES-3509

2.5 mm
A quarter-millimeter might not sound like much, but in bone splitting work, that small step up from 2.0mm to 2.5mm can be exactly the difference a practitioner needs between a blade that’s slightly too fine and one that handles the case comfortably. The NES-3509 offers that 2.5mm width, sitting right in the middle of this graduated chisel lineup.
Why the middle size often gets reached for first:
Wide enough to handle moderate ridge-splitting tasks without excessive repositioning
Narrow enough to maintain precise control over the split’s direction
A practical starting point before stepping up or down based on how the bone responds
Consistent with the same reliable edge geometry across the full size range
Ridge splitting isn’t always predictable from the outset. Bone density and thickness can vary even within a single surgical site, and having a mid-range chisel like this one available means practitioners can adapt without immediately jumping between the extremes of the size range.
Among the maxillofacial surgery instruments supporting bone preparation work, this 2.5mm chisel rounds out a set that starts fine and builds progressively wider, giving practitioners a genuinely flexible toolkit for ridge expansion and implant site preparation.
Built from surgical-grade stainless steel, this chisel withstands repeated mallet impact and sterilization cycles, holding its blade precision reliably across demanding surgical schedules.
