SS WHITE FG CARBIDE BURS #1558 PKG.10
Vendor: SS White
SKU: ISS27
Product Description:
The SS White FG-1558 (Item #17726) is a high-performance, cross-cut version of the straight round-end fissure bur. While it shares the same dome-tipped shape as the #1158, the addition of cross-cut notches on its blades makes it significantly more aggressive for rapid tooth reduction.
In my own words, the #1558 is the "heavy-duty" specialist for restorative work. The cross-cut design acts like a saw, allowing it to cut through tough enamel, old amalgam, or composite fillings with much less effort than a plain-cut bur. Despite its aggressive cutting power, the rounded (dome) tip ensures that the internal floor of the cavity remains smooth and rounded. This is vital for structural integrity, as it prevents the formation of sharp corners that could act as stress points and eventually lead to tooth fractures.
It is a durable, high-speed instrument designed for dentists who need to combine fast bulk removal with the safety of rounded internal geometry.
Key Benefits:
- Rapid Cutting: Cross-cut blades provide superior efficiency when removing dense materials or bulk tooth structure.
- Structural Protection: The dome end creates rounded internal line angles to better distribute occlusal forces.
- Versatile Performance: Ideal for both initial entry and the shaping of cavity walls in larger preparations.
- High Durability: Constructed from fine-grain tungsten carbide to maintain a sharp, effective cutting edge under heavy use.
