Compare Whiteside 3324, 3326, and 3330 molding router bits. Learn which profile suits your baseboard project and how to choose the right one.
Quick Answer
For a classic baseboard with a pronounced bead, choose the Whiteside 3324; for a subtler bead, the 3326 or 3330 are better. Match the bead diameter and profile depth to your trim style.
Bead Diameter and Profile Depth: What They Mean for Your Trim
The bead diameter determines how prominent the rounded detail will be on your molding. A larger bead (like the 5/16" on the Whiteside 3324) creates a bolder, more traditional look, while a smaller bead (1/4" on the 3326 and 3330) yields a subtler, more delicate profile.
All three bits share the same 1-5/8" large diameter and 3-1/2" cutting length, so they can handle similar stock sizes. The real difference lies in the bead size and the overall profile shape, which affects the visual weight of the trim.
AstraHP Coating: Why It Matters for Hardwoods
Each of these bits features AstraHP coating, which reduces friction and heat buildup. This is especially helpful when routing hardwoods or when you need a clean finish without burning the wood.
The coating also helps the bit stay sharper longer between sharpenings, which is a practical advantage for production work or long trim runs.
Trade-Offs: Intricacy vs. Simplicity
The 3324 and 3330 are described as making an intricate baseboard molding, meaning they produce a more complex, multi-step profile. The 3326 is also intricate but with a slightly different bead size, so the visual effect is distinct.
If you prefer a cleaner, more modern look, a simpler profile might be better—but these Whiteside bits are designed for classic, detailed trim. Consider the style of your room and the scale of your baseboard before choosing.
Decision Rules for Choosing Your Molding Router Bit
- If you want a bold, classic bead: Choose the Whiteside 3324 (5/16" bead). It creates a more prominent, traditional profile that stands out on tall baseboards. Check your baseboard height—taller boards often suit a larger bead.
- If you prefer a subtle, delicate bead: Choose the Whiteside 3326 or 3330 (both 1/4" bead). They offer a finer detail that works well in smaller rooms or with lower ceilings. Compare the 3326 and 3330 profiles side by side to see which shape you prefer.
- If you are routing hardwoods or long runs: All three bits have AstraHP coating, which reduces heat and keeps the edge sharper. Use them with a router running at the recommended RPM (14,000 for the 3324 and 3326). Always check the recommended RPM for your specific bit and adjust your router speed accordingly.
