Crosstech-Diamond Burs, FG, Modified Flat End Cylinder, 0.8 mm, 835KR-008, 5/Pk

Crosstech Modified Flat End Cylinder Diamond Bur (Medium, Blue, 0.8 mm) is an FG friction-grip diamond bur combining a cylindrical body with a rounded chamfer at the tip. This modification creates a smooth shoulder-chamfer margin transition, ideal for preparations requiring both parallel walls and a rounded margin profile.

• Medium grit (blue band) offers a versatile balance of cutting speed and surface texture — the workhorse grit for general crown preparation
• Rounded tip (KR/L modification) creates a smooth chamfer or shoulder-chamfer margin — reducing stress concentration at the margin
• Cylindrical body produces parallel axial walls for predictable restoration seating
• 0.8 mm diameter provides precise access in tight interproximal and subgingival areas
• FG friction-grip shank for use in standard high-speed handpieces
• 5 per pack; suitable for shoulder-chamfer margin preparations in ceramic and PFM restorations
