Buying advice

When choosing a router bit for doors and windows, consider the material you'll be working with (softwood vs hardwood), the radius of the edge you need, and your frequency of use. For occasional DIY, budget bits like Yonico suffice; for professional use, invest in brands like Freud or Whiteside. Always ensure the bit has a suitable bearing guide for consistent depth.
