Router Bit Profiles & Uses Guide
Identify common woodworking router bit edge profiles from Roundovers to Roman Ogees. Understand ball-bearing pilots, 1/4" vs. 1/2" shank rigidity, and maximum RPM safety limits.
Select Router Bit Profile:
Woodworking Cutting Profile
Roundover Bit
Pilot: Ball Bearing PilotSafe RPM: 18,000 – 24,000 RPM
📐 Resulting Wood Profile Edge:
Smooth convex 1/8" to 1/2" quarter-round radius.
🔨 Recommended Furniture & Millwork Uses:
Softening sharp table edges, chair arms, cutting board perimeters for splinter-free hand comfort.
Router Bit Shank Size: 1/4-inch vs. 1/2-inch Rigidity
1/4-inch Shank
Deflection & Rigidity: Lower (Flexes under heavy lateral load)
Max Safe Diameter: Up to 1" diameter bits
Best Tool Match: Trim routers, palm laminate trimmers, light hobby cuts.
1/2-inch Shank
Deflection & Rigidity: 4x More Rigid (Nearly zero deflection or chatter)
Max Safe Diameter: Large panel raisers (up to 3.5")
Best Tool Match: Stationary router tables, heavy 3+ HP plunge routers, deep hardwood profiling.
