Buying advice

When choosing a spiral router bit, consider the material you'll be cutting: upcut bits are great for chip removal in slots, while downcut bits prevent tear-out on the top surface. For general use, a 2-flute upcut bit offers a good balance. Check the shank size (1/4-inch or 1/2-inch) to match your router collet. Higher-quality carbide bits last longer but cost more. For occasional DIY, budget bits are sufficient; for frequent or professional use, invest in premium brands like Whiteside or Amana.
