Varieties of bevelling cutters for a hand router + other types of cutters and their description
Milling offers an almost unlimited number of possibilities for machining various workpieces. Forming edges, grooves and grooves of different shapes and depths - for each operation there are specific cutters for wood, which give the chance to get the job done as efficiently as possible.
What types of cutters can be in shape, size, design and type of blades you will learn further. We will pay special attention to edge milling cutters for a hand router.
Before you start choosing a cutter, you should at the very beginning decide on the fastening method, namely in which units the shank diameter will be measured - in millimeters or inches.
It will depend on which collet is included with the router - bushings into which the shank is clamped:
- If the size is measured in millimeters, the most common will be 6.8 and 12 mm.
- When the dimensions are in inches, you can only choose one of the two - 1/4 and 1/2 inches.
Please note that when converting inches into units of the number system, 6.35 mm and 12.
7 mm are obtained, but despite the small difference in millimeter the shank does not align with the inch collet and vice versa. The shaft of the milling machine rotates at a speed of up to 25,000 revolutions per minute, and therefore such even minor discrepancies can lead to at least damage to the tool.
Depending on the purpose and price, they can be produced in different design modifications.
This cutter is based on a steel block of the desired shape, and the cutting edges are welded to it. Due to the ease of manufacture, there are a lot of similar models on the market.
With replaceable cutting edge
They have a long service life, because knives for them are made double-sided - if the blade becomes dull, then it can be change to the other side.
Edges for cutting are ground at the base and when working with such tools, even in a hypothetical representation, the possibility of knife breakage disappears, but after a few sharpening the cutter will still have to be replaced.
Cutters can be inclined, vertical, or even with a spiral arrangement of blades. If we are talking about the first option, then pieces of wood will be chopped off from the workpiece, and inclined ones will be cut off, which will minimize the likelihood of chips and increase the overall quality characteristics of milling.
P about the material of manufacture and characteristics of the blade can be of two types:
In addition to blades, depending on where exactly and on the features of the shape that you want to get a groove in the workpiece, use the appropriate types of milling cutters for a manual router for wood.
They are required to cut grooves of the desired width and grooves inside the part or from the edge to the center. Most often, groove cutters are used to create a tenon-groove fastening, and if necessary, and also if the persistent structure of the milling machine allows, the groove width can be adjusted without replacing the cutter with the one that is larger in diameter.
This is the simplest tool that has the shape of a cylinder, and after using it, a groove remains in the workpiece, which has a rectangular section.
It is perfect for use with plunge milling machines, although it can be used with other models as well.
Their head for cutting has a rounded shape, and due to this, in the cut, the groove will resemble the letter "U", but much will also depend on the depth of the cut, because the walls are rounded off immediately from the workpiece surface and, or at first, for a certain time emanate from it at an angle of 90 degrees.
V -shaped fillet
By definition, "galtel" is precisely a semicircular notch, but the fillet cutters can also include the one that is given in the section of the V-shaped groove. If, when performing work, it will be assumed that the groin is made with different angles of inclination of the walls, then you will need to have an appropriate set of tools with you.
Structural ("dovetail" and T-shaped)
Such grooves in cross-section form a shape that looks like an inverted letter "T", and its base goes to the surface in the form of a regular trapezoid, and that side, which is larger, faces the central part of the workpiece.
This is one of the best types of connections, and the workpieces are inserted into each other, and it will be extremely difficult to separate them.
Together with fillet, it is used to obtain curly carving and edge processing. In cross-section, the grooves made outwardly strongly resemble the brackets familiar to all. You can also mill grooves in the center of the workpiece, or you can remove edges from the edge. If you make a complex drawing, then you will need to walk along its contour with a straight slot cutter in advance - this helps to simplify the centering process, which will definitely be required in the future and will reduce the load on the milling machine when using shaped cutting.
Most often they are made with a bearing, which makes it possible to process the edges and ends of workpieces not only by adjusting the support tabletop, but also according to a template.
In order to get the plane of the butt end from a piece of wood or a perpendicular face (we are talking about the upper part of the part that is being processed). If the cutter has a bearing, it will be possible to process the round edge. Directly, the bearing can be adjusted flush with the cutting blade or even have a smaller / larger diameter, which will expand the range of applications of the tooling.
In order to get an arched, straight or wavy curly edge - it all depends on the part of the cutter used, because you can soften the edge of the workpiece, or round it off (double cutters make it possible to do this in one go), create a folded edge or even a half-rod protrusion.
They are often used to make ornaments of complex shapes, and when choosing double cutters, you should pay attention to the possibility of adjusting the distance between the cutting cutters.
The Rebate Edge Cutter for Hand Router is used when you need to select a rectangular groin or even a quarter on a curved / straight workpiece. Using a double pass will produce a tenon of the correct size, and the recess depth will be adjusted by the position of the milling machine or thrust bearing.
Depending on the angle of inclination of the milling edge, they are used to prepare the workpiece before joining, machining parts pieces of furniture or receiving a decorative chamfer, which will then be connected into products of a polygonal or round shape.
They are used to obtain rounded grooves on the edge of a curly or straight workpiece.
To eliminate the possibility of skewing, the cutter is made with two bearings. The result of the work is similar to what you could use fillet groove cutters, but most often the use of fillet edge cutters is much more convenient.
Another name is multi-profile. Due to the fact that they are quite large and at the same time work with large workpiece surfaces, the use of such cutters is allowed on milling machines with a power of at least 1.6 kW.
For work, the entire profile of the cutter is used at once or in different combinations, and this makes it possible to obtain an edge of a given or standard shape.
The direct purpose of the cutter will be the processing of blank edges to obtain a semicircular protrusion. In addition, there are many additional ways to use it - if you process a rectangular workpiece with such a cutter on both sides, then it will most likely become a core.Moreover, with its help, profiles with a chamfer, as well as edges of complex shapes, as well as hinge-type joints (when processing a workpiece in tandem with a molding or fillet mill) are obtained.
Such cutters are used in order to join and unite wood blanks - to combine them at the edge (for fillet connection) or the end part (in order to get wide boards from several small ones).
Combination cutters combine tenon and groove, and they are also designed to create both of these elements in one pass. Using milling for this purpose helps to increase the bonding area of the boards and grinds the surfaces to maximum contact with each other.
Combined universal type
Such milling cutters for a hand-held wood router make it possible to obtain aligned planes with a groove and a tenon, which are placed at an angle to each friend. The same cutter is used for two spliced workpieces - since it does not need to be changed, this helps to significantly reduce the processing time.
The set is applied from two separate cutters - to create a groin in one workpiece and a tenon in the second.
Additional adjustments and measurements are not necessary, because the dimensions of the cutting edges were calculated when creating the tool.
To create a lining
They are used according to a similar groove-and-tenon principle, but they make it possible to obtain a figured connection with a large contact point of blanks, and this improves the characteristics of the lining created in a similar way.
These are type-setting cutters that give the master the opportunity to place the cutting blades on the axis in the order he needs. They are made up of a base, cutting blades, thrust bearings, lock nut and lock washer. When changing the configuration, the cutter base is not removed from the collet of the milling machine, so that the original setting is retained
The main purpose is to process decorative character for the edges of parts , which are needed to create panels.
Figurine cutters have bearings, and therefore it will be possible to work with curly and rectangular blanks. Due to the fact that the panels are usually large parts, the average cutter size is usually from 5 to 7 cm, and for normal use it is worth using a milling machine with a power of 1.5 kW or more.
They are used for incomplete processing of the panel, because the shape of the cutter will imply a selection that starts from the thrust bearing - this is will not allow you to immediately receive a spike for inserting the infill into the frame. Additional edging will be required to form.
They help to significantly simplify the work process, because the part can be machined even in one milling pass, and This is the figured part of the panel, and the spike for the cut out groove in the frame.
Such cutters are used to create skirting boards of different shapes, but as practice has shown, their capabilities are much wider - a lot depends on how set up and even hold a milling machine. After processing, a decorative frame and a spike connection will appear on the workpiece. These are the main varieties of wood cutters for hand tools, but it is also worth considering the fact that each of them will be made in several sizes, because professional carpenters must have a separate cabinet for storage.
