![]() ![]() These drill bits can be used on regular drills as well as in the bench drill for different kinds of material such as plastic, PVC, fibre etc. But you had better consider the drill bit material and geometry before you buy it. When you have all types of above wood drill bits, you can work easily on your project. Because softwood can drill easily and chips should remove quickly from the hole but hardwood doesn’t need this.Īccording to the geometry of the hole, you can choose, which drillbit is suitable for your task. So for the softwood, you should have deeper flutes with high flute capacity and for the hardwood, you can use deep flutes with low flute capacity. Softwood will cut easily and hardwood will not cut quickly. So pay attention to the drill bit material when you buy it. When adding these materials will harder the drill bit. Most wood drill bits are made with HSS and some characteristics have been added by mixing cobalt, titanium etc. When you select the right drill bit, you should consider the drill bit material. Softwood can be drilled with high RPM and lower RPM should be used for the softwood. As you are well aware, those are hardwood and softwood. This is the most common type of drill bit type for home use. This type of drill bit is works well for holes up to one inch in diameter and are useful for home repairs, maintenance and building projects with metal, wood or ceramics. Spade: Shaped something like an oar with a point in the middle, these heavy-duty bits are for drilling large holes in wood. Twist drill bits, also called fluted bits, are used on light metal, wood, plastic, metal, ceramic and masonry. It is useful for general-purpose drilling into wood, plastic, and light metals. When you select the right drill bit, you should know the hardness of the wood first. Here are some of the most common: Twist: This is the most common type of drill bit. How to Select the Right Drill Bit For You? Most regular drill bits are Multipurpose drill bits and there should be a proper cutting angle to use.Įlse it will not properly cut and remove the material. ![]() ![]() There is a V shape end of the drill bit and it can be used from many kinds of wood and steel. This reduces friction on the screw as it goes into the wood.This is the common drill bit we use. Metal drill bits need extra strength and heat resistance so they don’t get damaged when you use them, so they’re coated with a stronger metal, like titanium or black oxide. You can use paraffin wax that is used for canning, or you can rub a candle onto the screw, which is also paraffin wax. Material Metal drill bits tend to have a black or gold finish while most wood drill bits only have a shiny silver finish. The fibers of a dense wood species are more resistant to crushing by the threads of the screw, so it is good to go up by one size on your drill bits, as long as the bore of the hole is still smaller than the threads of the screw.Īnother thing that can help a lot when working with very dense wood species is to apply wax to the screw threads. These species include but are not limited to: hard maple, ash, wenge, ironwood, ipe, white oak, etc. This applies whether you are using the eyeballing method or going by numbers.Įxtremely dense wood species require a slightly larger hole. Having a slightly smaller hole will give a more secure hold in a softwood. Because softwood is less dense, you should should drill a slightly smaller hole (one size down), because the fibers can be crushed more easily. You’ll notice on the table above that the drill bit size is different depending on whether you are drilling into hardwood or softwood.
