Sharp and remarkably precise, equipped or not with a ball bearing, strawberries are mounted on a router handled on the fly or under table. They allow to profile the wood to create grooves, rabbets, moldings, assembly profiles, bowls...

Strawberries: a wide variety of tools
Plunging cutters can work both vertically, by digging the material like a wick, and horizontally, following a defined path.
This stepped mill performs in a single operation oblong holes milled.
Quart-de-rond and other moldings are often equipped with a pilot, because the profile to be made follows the song of a piece of wood or the periphery of a frame.
The profile can however be modified by adjusting the depth of the machining or by using a different diameter driver.
Strawberry for dovetail
This traditional assembly can be realized with a conical cutter.
To assemble drawer sides, the guide is made with a special device: the cutter has a pilot sliding in a jig-shaped comb.
Strawberry for butting
The multi-fillet cutters are used to abut the end wood when the depth of the cuts is important.
To simplify the guide and to avoid penetrating too deeply into the material, the cutter is provided with a ball bearing at its end, called pilot.
Drill for bouveter
To assemble boards edge to edge, this unmanned cutter is directed by the parallel guide of the machine or the milling table.
The profile of the first song is obtained by placing the board at the place, the second board is returned to obtain an inverted profile.
Modular milling cutter
The cutter is here composed of an axis on which we can mount one or more cutting discs, separated by thick rings and drivers of different diameters.
This tool allows you to make tongue and groove joints, false tongue or straight tails, and to modulate the width of the grooves.
It is also possible to make notches for slats.
Reducing sleeves for routers
Ø8 mm milling shanks are largely the most common; it is better to limit yourself to this standard to begin.
However, powerful machines often have a larger diameter collet. The reducing sleeves then make it easy to mount the cutters whose tail is of a smaller diameter.
There are indeed tails of Ø 6/8/12 mm, and 1/4, 3/8 or 1/2 inch (6.35 / 9.54 / 12.7 mm) for the Anglo-Saxon standard. You can also change the clamp of the machine.
With a fixed driver
The pilots are small ball bearings mounted on the axis of the strawberries.
Always use original screws due to high rotation speeds (10,000 to 30,000 rpm).
The diameter of the pilots depends on the shape of the cutter.
When the pilot is placed between the tail and the sharp edges, it is called strawberry to copy.
These cutters can reproduce complex shapes, by clipping or digging, from a template.
With copying rings
To make small and complex cuts, for example to cut hinges with a straight cutter to groove, the copying rings are particularly indicated.
Placed projecting under the sole of the machine, the rings are guided by a machining jig cut out of a panel.
With a mobile pilot
Modular milling cutters make it possible to place or not pilots of different diameters, above or below the discs to be creased; they can thus adapt to a large number of situations.
By the end
Most pilot burs are guided by their end.
This is particularly the case of strawberries to chamfer, to burr or edge on edge, which do not work in diving.
With a machining fixture
Router burs lacking a driver need to make gutter-type machining fixtures, whose width is equal to either the diameter of the sole of the machine or the diameter of the copying ring set up under the sole, around strawberry.
Maintenance and storage of strawberries
Cleaning a router bit:
Resin deposits can be removed with a caustic soda bath.
Provide a glass container and a hooking system to soak the strawberry upside down, without touching the bottom.
Sharpening a wood bur:
Tungsten carbide and high speed steel tools can be sharpened with a diamond stone and a lot of precision; better to call a professional.
Lubrication of a wood bur:
When servicing the pilot cutters, remember to remove the small ball bearing.
A little special oil applied at the time of reassembling the tool will extend its life.
Handling wood strawberries:
Handle strawberries with care, preferably wearing protective gloves as the edges are sharp.
There are storage kits that are convenient for transportation.
Storing wood strawberries:
The sharp edges are fragile and must never clash. The ideal storage is to plant the tails in holes of the same diameter.
The support can be a piece of wood, to be stored in a drawer, a box or on a shelf.
