And to help you through it, we have created an extensive buying guide to make your choice easy and effective!
Types of Rasps
Rasps are classified according to their size, shape, and teeth density and each is used for different materials and functions. Therefore, it is necessary to know what you want to use a rasp for when buying it. So let us break down different types of rasps for you.
Cabinet rasps are usually used for small, soft pieces of wood. They are used by professional furniture makers to smooth out spots in a manner that does not harm the wooden surface or finish. Some cabinet rasps come with pointed ends that act as picks to take out extra chunks of wood that result from rasping and lie in crevices.
Square rasps are usually flat and have a square cross section. However, sometimes they are knife shaped and narrow at the end to fit into holes and openings. Square rasps are used for thin and flat surfaces and square holes. They come in a variety of sizes too so you can choose according to the length of your surface or the depth of your hole.
A modeler’s rasp is used to make extremely precise cuts and intricate pattern work often found on ornate woodwork and furniture. It is sharp at the end with a flat base surface and a long handle to provide dexterity and accuracy. Modeler rasps are best employed when creating projects that require delicate work like architectural prototypes or sculptures.
Horse rasps, as suggested by their name, are outdoor instruments used to file horse hooves, getting dirt and grime out of farmyard applications. They are usually flat and thick and have two filing faces with varying teeth that can help scrape off both large pieces of dirt and smaller dust particles. However, they are also well applied on flat surfaces like wooden walls and doors.
Rasps with cranked necks
Cranked necked rasps are similar to paint scrapers and have long flat files attached to handles through cranked tangs. The curvature of the neck is useful for curved or bent surfaces where confinement is an issue.
Needle rasps are as thin as, well you guessed it…needles! They are relatively small and allow for extremely delicate work. Often, needle rasps are made to operate on musical instruments like the violin, the viola, or the guitar. Needle rasps usually come in packs of 4 or 6.
Round raps are similar to needle rasps but are thicker and hollow with a round cross section. They are employed to smooth out wooden or metal curves. They are also used to make new holes and clear them up for screw fittings or other wooden structures. Round rasps are durable instruments, often made with hardened steel and so sometimes resemble a long, round grater. Their results are precise and efficient and faster than other, more common rasps.
How To Choose a Rasp File
There are specific features to look out for when buying a rasp because they determine the quality and usage of the rasp. Some of these are:
Type of teeth:
If you are looking for a highly smooth finish that looks impeccable and ornate, go for a fine teeth pattern. If you want a regular repair job rasp that can be utilized for other purposes, an average sized teeth density will do just as well. And if you need to remove materials quick and fast, a coarse rasp will work best.
After knowing your teeth density, you should pick out the size and shape of your rasp. A flat rasp works well on planes without curves or ridges. A round rasp, also known as a rat tail, is used for finishing up niches and notches as well as other irregularly shaped objects. However, if you are looking for a rasp that meets both these needs in a single tool, go for a half-round rasp that sports both flat and round surfaces.
Rasp handles are often made of either wood or other synthetic materials like plastic or pvc. Ergonomic and long handles provide for greater comfort and dexterity. Some handles are detachable and can be fixed onto other rasps so you quickly change tools while on the job.
Some More Tips:
If you want to go a little more versatile, always go for a rasp that is multi-sided. Rasps with 2 or 4 faces are often available. In addition, sets of rasps are also available that come with one of each.
You should also remember to use rasp teeth as fit for your work because any material you file away will be lost. So, choose wisely!
General purpose rasps are uniform in teeth density and depth, and can often leave the filed surface ragged and uneven, requiring a significant amount of clean up. So do not choose them for surfaces you want to put on display.
High-quality rasps, often called pattern makers because of their smooth finish, have staggered high-density teeth that leave the surface soft to touch and clean to look at. However, they can be a bit expensive so get these if you are looking for specific activities.
How Much Does a Rasp Cost?
Rasp files come at a variety of costs, some extremely cheap, others a fine work of art and priced as such. However, you can get a good one that is in your price range and includes the features you want!
