Buying the best drill bits for wood is not an easy process. In this article, we help you make this decision by exploring the best options available on the market. The choice will generally come down to the type of hole you intend to make.
How Do You Pick The Right Drilling Bit For Wood?
Understanding the various types of wood available is key in picking the right drill bit. The two types of wood are hardwood and softwood. The general principle is that hardwood comes from trees that only contain leaves while softwood comes from those that bear cones.
Examples of hardwood include beech, ash, cherry, maple, ebony, mahogany, rosewood, oak and teak. Softwoods include pine, larch, redwood, hemlock, yew, spruce, and firs. Hardwoods are much harder to drill than softwoods and hence requires more drilling effort.
For a regular cordless or corded drill, there are various drill bits that can be acquired. It’s important to understand how each of these drill bits can be used so as to choose the right one. The drill bits designed for wood are generally made from softer metals and have tips and flutes for a better drill in wood.
Not all bits will work for hardwood. This means you have to make sure you get the right bit that will support your project. Some of the different types of drill bits that can be used with wood include spoon bits, wood spade bits, lip & spur bits, Forstner bits and auger bits.
Picking the right drill bit for wood, therefore, requires some basic understanding of what is available on the market. You then need to determine the quality standards required as well as the type of material to choose.
Some of the available bit materials include steel, black oxide, titanium, zirconium, carbide, and cobalt. Choosing high-speed bits may be an added advantage since they stay sharp for a longer period of time.
Black oxide bits gives you a good balance between durability and hardness and are used for many applications.
