Freud 34-100 1/16-inch Radius Rounding Over Bit
The Freud 34-100 is a versatile rounding over bit with a 1/4″ shank, designed to soften furniture and cabinet edges. It pairs well with beading tasks when used with appropriate bearings and washers. It cuts a wide range of materials, including plywoods and hardwoods, and is suitable for both handheld and table-mounted routers. Best for projects requiring rounded corners on furniture edges. Limitation: for very tight radii or intricate contours, a smaller-diameter bit may be more precise.
Whiteside 2000A Roundover Router Bit
With a 1/16″ radius, 5/8″ large diameter, and 1/2″ cutting length, this bit is designed for clean, rounded edges on a range of woods. It provides a classic, smooth edge suitable for cabinetry, frames, and decorative trim when used with a 1/4″ collet. Best for users who want a durable, straightforward roundover solution. Caution: the bit’s large diameter requires cautious routing at higher feed speeds to avoid burning, especially on dense hardwoods.

This set includes multiple radii, notably 1/16″ and 1/8″ among others, with a 1/4″ shank and durable carbide blades. It’s a practical all-in-one choice for hobbyists and professionals who need versatility for stencil work, edge treatments, and varied contouring. Best for projects requiring quick radius changes without swapping bits. Caution: avoid cutting metal or non-wood materials; ensure proper RPM and secure clamping for safety.
Buying Guide: How to Choose the Best 1/16″ Roundover Bit
What edge radius is right for your project? For most furniture and cabinetry, a 1/16″ radius provides a subtle, refined edge. Larger diameters or radii produce more pronounced rounding, so match the bit to the edge profile you want.
Which shank size fits your router? Most small-to-mid size routers use a 1/4″ shank, which balances control and compatibility. Always confirm your collet size before purchase.
How durable should the bit be? Carbide-tipped and solid carbide bits offer longer life and better edge retention on hardwoods. If your work involves softwoods or plywood, standard carbide bits often suffice.
What materials will you cut? These bits are designed for wood, plywood, MDF, and similar composites. Avoid metal, stone, or non-wood materials to prevent damage to the bit and tool.
What’s the project environment? For intricate profiles with detailed contours, consider a set with multiple radii to handle various parts without frequent bit changes. A pilot bearing or compatible bearings can expand beading or edging capabilities.
Frequently Asked Questions
- What is a 1/16 inch roundover bit best used for? It creates a subtle rounded edge ideal for furniture, cabinetry, and fine trim where a gentle touch is desired.
- Can I use a 1/16″ roundover bit on plywood? Yes, but take precautions to reduce tear-out by using a climb cut or sharp bit and proper feed rate.
- Is a 1/4″ shank necessary? A 1/4″ shank is common and provides stability; ensure your router’s collet matches the shank size.
- Are carbide bits worth the extra cost? For repeated or heavy use, carbide bits offer longer life and cleaner cuts, especially in hardwoods.
- How do I avoid tear-out with roundover bits? Use clean, shallow passes, secure stock, and sharp bits; consider climb cutting on end grain with caution.
- Can I mix radii in a single project? Yes, a multi-radius set can create complex edge profiles, corners, and moldings for layered trim builds.
