Interesting facts about files, rasps, application, cut, shape and type
Files or rasps can be used in a variety of ways in workshops and take on numerous tasks. In addition to roughing and finishing workpieces, this versatile tool can be used for filing, smoothing, correcting, filing smooth, reworking, polishing, grinding or filing. In our online shop, which not only specializes in violin making tools, but also in high-quality files and rasps, you will find a specialized selection of high-quality files and rasps. The right filing cut In addition to the quality of the alloy, hardening and tooth shape, the number or number of cuts plays an important role in choosing the right file or rasp. The cut number according to DIN 8349 corresponds to the number of cuts per centimeter depending on the total file length. The higher the number, the finer the division. In the case of the files, a distinction is also made between the type of cut. So there is single cut, cross cut and rasp cut. Hand-cut files and rasps show irregularities in the teeth due to the way they are manufactured. However, the tooth pitch and number of cuts also apply here. In the case of rasps, the number of cuts in accordance with DIN 8349 is used to calculate the number of cuts, i.e. the number of teeth per square centimeter depending on the total length. With the rasp shape of this type of file, the teeth (blows) protrude far from the blade. A rasp also removes a lot more material than a regular file and therefore has this special name. When using a Rasepl, very coarse and fibrous cut surfaces arise, which can then be smoothed with a file.
Single-cut
With a single-cut file, the cut usually runs across, at an angle or in a curve to the file blade. With an inclined or curved course, the chip flow is facilitated, but the file pattern is different. This cut is mainly used in the processing of soft materials, when sharpening and turning, as a lathe file. The advantage of a single cut is the very clean image. The disadvantage is that such files clog faster because the chip cannot be removed as easily.
Cross cut
The notches on a cross-cut file blade intersect at an acute angle. First of all, the so-called bottom cut is made during production. The top cut is then cut over this. As a rule, the lower cut is deeper and more often per cm than the upper cut. Visually, the teeth of a cross cut look diamond-shaped. This is important because it allows the teeth to break the chip and counteract the formation of scoring. A cross cut is recommended when working on ferrous metals and hardened materials
Rasp cut
During the rasp cut, the teeth sit individually, i.e. at specific points on the file blade. With this cut you can work hard stone, but especially leather and wood. It is important here that the teeth are not in an even arrangement, as otherwise grooves will form when filing or rasping. A certain offset is an advantage here. Hand-cut rasps give the most beautiful rasp image. There is no regularity in the arrangement of the teeth, which makes scoring almost impossible.
Conversion table German cut Swiss cut It is important to distinguish
between a Swiss cut and a German cut. Vallorbe files are equipped with the Scheizer cut and Friedr. Thick files, and Pechar's rasps with the German cut. In the following you will find a conversion table for German cut into Swiss cut, number of cuts and teeth per cm. This allows you to compare the files quickly and easily.
Select the right file or rasp shape and type for every task
There is the right file shape or rasp shape and file size for every application and task The flat file is rounded off and bumped for the straight, even surface and the clean edge. Round files and half-round files are used wherever you have to cut a shape in a concave manner or file a hole. Especially for rings and ring filing, there is a raised version of the half-round file called a ring file. Fluted files with parallel milled transverse grooves are for hand or thumb rests on blades and knives. The size of a file is also crucial. In addition to the normal file sizes of 150 mm, 250 mm and 300 mm in length, there are very fine needle files. In between are the Habilis files. Valtitan titanium files are the right choice for working on hardened steels.
Flat file
The flat file is rounded off and bumped for the straight, even surface and the clean edge.
Round file
Round file is specially designed for filing holes.
Half-round file
The half-round files are used wherever a shape needs to be cut out or a hole needs to be filed.
Ring file
Especially for filing rings and tight radii, there is an increased version of the half-round file called a ring file, a high-half-round file or a high-half-round file. As a special feature, this half-round file has a high curve. As a result, the sides are steeper and you get into tighter curves. This file is preferably used for filing the inside of the ring during ring production and is suitable for steel (unhardened), metal, wood.
Fluted file / grooved file
A fluted file or grooved file with its parallel milled transverse grooves is intended for hand or thumb rests on blades and knives. These files can be used to quickly create different grip patterns on handles.
Needle file
The length of needle files is measured over the entire length and given in mm. Needle files are available in lengths of 100mm, 140mm, 160mm, 180m and 200mm. The needle files made from steel with a high carbon content by Vallorbe and Friedr. Dick stand for the highest Swiss-made quality. We particularly recommend our needle files for machining steel, steel alloys, soft metals and finishing operations.
Habilis file
Needle file Valtitan titanium file
The very fine and small needle files are available in different lengths. The Valtitan titanium needle files are an exception to the needle files. These are to be used for hardened metals. It is important to apply gentle pressure here so that the teeth do not break out.

How do I care for my file properly?
The most important thing when caring for files is to clean them after work is done. Preferably with a file cleaning brush across the cut. This way you get rid of any solid particles that may be stuck in the teeth of the file. Files should be stored in a clean and dry place, otherwise they can rust, which attacks the teeth and has a negative effect on their sharpness. It is also important to ensure that the files do not hit each other or are not stored on top of each other. Otherwise the teeth will quickly become blunt.
