Choosing the right planer blade can be a tricky and time-consuming task, but it doesn't have to be! Learn how to make the best choice for your needs with this guide.
A quality planer blade can make all the difference when it comes to getting a smooth surface on wood projects. Getting the right type of blade for your specific needs can be tricky, but this guide will help you make the best choice for maximum performance.
Consider the type of wood you plan to be working with.
Different types of wood require different blades. Softwood such as pine, spruce, and fir, requires blunt-toothed blades that will make a finer cut. Hardwood such as oak, walnut and cherry need a sharper blade with teeth on both sides that will make a deeper cut. Choose the appropriate type of blade to match your project.
Understand the differences between the various types of blades available.
There are three types of blades available: straight, helical, and disposable. Straight blades have either two or four cutting edges and can be adjusted for the depth of cut you need. Helical blades have multiple cutting edges that are positioned at a slight angle which helps create less tear-out when planing. Disposable blades are only used once and then discarded making them perfect for larger projects as they tend to sharpen faster than other types of blades. It's important to understand the differences between the various types of blades available so you can make a better informed decision when purchasing your planer blade.
Decide on a blade size and shape that best fits your need.
When choosing a planer blade, it’s important to pick the right size and shape for your project. The common sizes are 8” and 6” blades. The shape depends on the type of wood you will be using as well as whether you need a balance between speed and quality of cut. Blades come in straight, curved and graduated profiles so it's important to choose one that best suits your needs. Taking the time to research and select the right blade type will help you get the best results possible.
Evaluate individual blade quality by checking for uniform hardness and sharpness.
It’s very important to evaluate the individual blade for hardness and sharpness. To test for hardness, use a file or grinding stone to rub along the cutting edge of the blade. A quality blade will not mark easily. To test sharpness, hold a piece of thin paper against the blade and see if it cuts smoothly. Evenly spaced teeth in comparison to sharper ones will generally provide better results because they give an even finish. You want uniformity with your planer blades so be sure to check them closely before selecting one.
Get the proper alignment for your blades to avoid warping or jamming during use.
Poor alignment of planer blades can cause warps in thin stock or even jammed knives! Be sure to properly align the blades on your unit with the right distance between the bodies of the knives and make sure they are at an exact 90-degree angle between each other. This can be done with a straight edge or simply by eye. Check this before use and if there are any discrepancies, stop your project and readjust as needed. Doing so will save you time and money in the long run!
