While moving the bit up and down in the drill hole usually clears the swarf, you may have to remove it manually. ![]() Sometimes, especially with soft material, the flutes of the drill bit get clogged with swarf causing the bit to resist. ![]() The design of a drill bit is to cut into the material and remove the waste material called “swarf” through the flutes. If you find the drill bit resists too much, you may need to change the drill bit or sharpen it. You may break a thin bit by overly forcing it. Like a saw, you need only to apply constant pressure to the wood but not excessive force. The result is that you have to use less force and there is less chance of your drill bit shifting the hole.ĭrilling directly with a thicker drill immediately can cause the center of the hole to shift and cause problems in fitment. Regardless of the size of the final hole you require, start the drilling process by drilling a pilot hole with a thin drill bit. Your holes will be more accurately placed. It will prevent your drill bit from “wandering” when you first apply the drill bit to the surface of the wood. Use an awl, punch, or a sharp nail to punch an impression at the drill location. When you start drilling a hole, the bit tends to wander, because of the way it spins. Here are a few useful tips to make your drilling jobs easier: Use a Punch Sometimes, drilling a simple hole into wood can be more challenging than you expect. Best Practices for Drilling Holes in Wood Because of the structure and hardness of a drill bit, you can use it to drill into harder material. Metal tips typically come in black, golden (frequently coated with titanium dioxide finish) and copper color.Īlthough metal drill bits are normally hardened to a high degree, the titanium dioxide and other coatings protect the surface from chipping and overheating. The cutting edge of a metal bit is extremely critical and needs to be touched up from time to time. Brad Point Wood Drill Bit (Image: Amazon) Metal Drill Bits Twist Drill Bit Set (Amazon)Ī metal drill has a cylindrical structure that has fluted ridges along its edges and a beveled tip. Typically, wood bits come in black and silver, but you may find other colors as well. In such a case, the difference is more subtle – the material used will be softer, and the bit may be differently colored or marked. You may also come across wood drill bits that resemble metal drill bits. We use spade bits to create oversized holes, that exceed the maximum diameter of the drill bit that you can fit into the chuck of a power drill. You can easily identify the drill bit as it has a unique shape. If you are looking at a spade bit, these components are well-defined. Wood Drill Bits Spade Drill Bit Set Titanium Coating (Image: Amazon)Ī wood drill bit has a “spur” (also called “brad” – see below) and a lip. Fortunately, there are a few clear distinguishing features that set one apart from the other. It is crucial to tell the difference between a wood drill bit and a metal drill bit to get the best results. How to Distinguish a Metal Drill Bit from a Wood Drill Bit In such a case, you will find little difference between metal and wood drill bits. An exception for metal drill bits is if the diameter is small. ![]() A metal drill bit if used on wood can damage the wood. Unless you use it for drilling soft and thin metals, your drill bit won’t work. If you use a wood drill bit on metal, you may end up destroying the bit. In this post, we attempt to clear this issue and any other ambiguities that may surround the subject of drill bits. The question of whether you can use metal drill bits for wood is a much-asked question.
