Point Cutting Roundover Bit vs Standard Roundover: Key Differences

Compare point cutting and standard roundover router bits for CNC and edge trimming. Learn which profile suits your project and when to choose a Whiteside point cutting bit.
Quick answer
A point cutting roundover bit creates a V-shaped groove with a rounded top edge, ideal for decorative lettering and CNC trimming. A standard roundover bit produces a simple rounded edge without the V-groove. Choose point cutting when you need both a decorative V-cut and a soft edge in one pass.
Why the cutting tip shape matters
The main difference lies in the tip geometry. A standard roundover bit has a bearing or a flat bottom that rounds only the top edge of the workpiece. A point cutting roundover bit has a tip that is part of the cutting edge, so it cuts a V-shaped groove while also rounding the edge. This makes it suitable for decorative trimming and fine lettering where you want a soft, rounded top over a V-groove.
For CNC work, the point cutting design allows the bit to plunge into the material and create the profile in a single pass, reducing tool changes and machining time. Standard roundover bits typically require a separate V-groove pass if you want a similar decorative effect.
Trade-offs to consider
Point cutting roundover bits are more specialized. They cost slightly more than a basic roundover bit of the same radius, but they eliminate the need for a second tool. If you only need a simple rounded edge on straight or curved cuts, a standard roundover bit is more economical and simpler to use.
Dust and chip clearance can be different. The point cutting design can trap chips in the V-groove if you cut too deep in one pass. Standard roundover bits usually clear chips more easily because they cut only the edge.
Trade-offs at a glance
- Profile shape: Point cutting produces a V-groove with a rounded top. Standard roundover produces only a rounded edge. If you want the V-groove, choose point cutting; if you only need a roundover, standard is simpler.
- Number of passes: Point cutting can create the decorative profile in one pass on a CNC. Standard roundover requires a separate V-groove bit for a similar effect. For production work, point cutting saves time. If you run a CNC sign shop, point cutting bits reduce tool changes.
- Cost vs. versatility: Point cutting bits cost more (e.g., Whiteside 1572 at $27.99) than a basic roundover bit of the same radius. However, they replace two bits. For occasional use, a standard roundover bit plus a separate V-groove bit may be more cost-effective.
Product facts
- 1/4″ Point Cutting Roundover Bit – Whiteside 1572 (AstraHP Coated): This 1/4″ point cutting roundover bit with AstraHP coating is designed for decorative trimming and fine lettering, with a 1/4″ radius and recommended RPM of 16,000. The 1/4″ radius works well for small signs and detailed edge profiles where you want a subtle V-groove and a soft edge in one pass.
1/4″ Point Cutting Roundover Bit – Whiteside 1572 (AstraHP Coated) - 3/8″ Point Cutting Roundover Bit x 1/4″ Shank – Whiteside 1574 (AstraHP Coated): The 3/8″ point cutting roundover bit gives your workpiece the V-shape of a V-groove but with a rounded top edge, with a 3/8″ radius and 3/4″ cut diameter. The larger radius creates a more pronounced decorative edge, ideal for larger letters or thicker material where you need more visual impact.
