Hinge Boring Bits

The application for boring bits often seems straight forward: we’re either going to drill all the way through the material or we’re going to create a flat bottomed hole in our product for dowels. But when it comes to creating a large hole in a material, the choice of which drill to use becomes less obvious. A few things to consider:

  • A thru-bore (V-tipped) bit may be purchased with a cutting diameter up to 20 millimeters. These bits are great at puncturing cleanly through double sided material, but may get too hot if the material is too thick or is really dense (like a hardwood).
  • Brad point (dowel-tipped) drills are made in diameters up to 18 millimeters. They’re great for smaller, flat-bottomed holes, but at the larger diameters they may not be your best option.
  • Hinge bits are traditionally used for large flat-bottomed holes, but they can also drill all the way through materials and still leave a clean finish. While the application is often similar to a brad point drill, they have a different design that makes them more versatile they have a pointed spur in the center of the cutting radius, as well as two spurs on the outside cutting diameter that provide clean entry into the material. There are also two carbide cutters inserted at across the inside of the cutting diameter. Here is our selection of hinge bits: http://www.toolwolf.com/product/product-category/hinge-boring-bit/
  • Overall, hinge bits are one of the most versatile types of boring bits. Check out this link at WoodMagazine.com for more information about the best choices for making large diameter holes
