The F-25 Ogee Diamond Router Bit – Position 1 is a sintered metal-bond, continuous rim diamond router bit built for aggressive shaping of ogee edges on quartz, granite, and quartzite.
What “F-25” Means
• F = Ogee profile
• 25 = 25 mm profile height
• 25 mm equals 1 inch
This produces a deeper, more decorative ogee edge compared to the 20 mm version. The profile features a larger upper curve and more pronounced drop—excellent for premium countertop installations.
What “Position 1” Means
Position 1 is the coarse shaping step, using approximately 30/40 grit diamonds.
This stage:
• Removes stock rapidly
• Forms the complete 25 mm ogee shape
• Prepares the edge for finer shaping and polishing
The sintered metal bond contains high diamond concentration, which continuously exposes new diamonds as the bit wears. This gives long tool life, especially on quartzite.
The continuous rim design provides smoother contact with the stone, cleaner shaping, and fewer chips.
BOLT / THREAD SYSTEM (IMPORTANT)
Stone router bits do not use a half-inch arbor.
✔ True arbor shaft: 10 mm
Each bit includes two bolts, both with 10 mm shafts, but different threads:
• 10 mm shaft with 10 mm thread
• 10 mm shaft with 8 mm thread
This system fits nearly every portable stone router in fabrication shops.
Both bolts are included with every router bit.
OTHER PROFILES AVAILABLE
We carry a full lineup of shapes:
• F-20 Ogee
• V-30 Bullnose
• E-Shape (Bevel)
• L-Shape (Cove)
• H-Shape (Dupont edge)
