EXPERT KNOWLEDGE ROUTER BITS CUTTERS
Router bits cutters, end mills, wood milling cutters, TC milling cutters, etc. are terms for milling tools that can be fixed in the collet chuck of a milling machine by means of a Shaft.
We offer our high-quality milling cutters in various versions with different effective lengths, diameters, radii, etc. and with carbide as the cutting material. However, all of the milling tools we offer have one thing in common: the highest quality and precision for demanding professional use. Wear-resistant cutting edges and high concentricity ensure a long service life and the cleanest cutting edges.
- HM/HW stands for carbide-tippedmillingcutters orHW. Carbide alloys contain a mixture of tungsten carbide and cobalt.
- Solid carbide (solidcarbide). Groove-cutting machines with a small diameter or Groove cutters with a long Effective length are primarily made of solid carbide. Here, the entire milling cutter consists of one piece of carbide. The cutting edges, milling head and shaft are made from one piece.
Our range of milling cutters - characterised by high processing standards
- High material quality for a long service life and clean, tear-free milling edges with a uniform cutting pattern.
- High concentricity due to precisely ground shafts ensures smooth running and perfect surface quality on the cutting surfaces.
- Thick carbide inserts are soldered into carbide-tipped milling cutters. This ensures greater resistance when machining hardness materials.
- Production of all milling cutters in accordance with EU standard EN 847-1 and -2.
- For milling cutters with thrust ball bearings, we use high-quality ball bearings for precise guidance along the template or workpiece edge.
Shaft diameter
To clamp the milling tools in the collet chuck of a milling spindle, the Diameter of the milling shank and that of the collet chuck must match. Most Routers or Milling motors are supplied with an 8 mm collet. Therefore, most common end mills are available with an 8 mm shaft. Shafts with a diameter of 10 mm /12 mm or 12.7 mm are often used for routers with a particularly large Effective length (especially Groove-cutting machines) for reasons of stability and safety. Particularly filigree milling cutters, on the other hand, are offered with shafts in 6.35 / 6 / 5 / 4 / 3.2 mm due to their small size. Shaft diameter and collet diameter must match. Shaft diameters with decimal places are converted inch dimensions that are specified for milling cutters from the USA or England. 1/4" (6.35 mm), 3/8" (9.5 mm), 1/2" (12.7 mm).
Details of the milling cutter
All important information about the milling cutter is engraved on the milling cutter shank. Depending on the manufacturer, the following data is given (data may vary depending on the milling cutter type and manufacturer):
- Manufacturer
- Item number
- Date of manufacture (usually coded information)
- Permissible speed "n max."
- MAN = suitable for manual feed
- Concentricity tolerance in mm, e.g. e=0.1
- Milling cutter material (cutting material), e.g. carbide for hard metal
- Cutter dimensions, e.g. "R" for radius / "D" for Diameter / "°" for burr specification for chamfer or burr cutters
- Shaft diameter "S" in mm
- Clamping depth ">|", labelled with a line with an arrowhead
Clamping depth
Always observe the minimum clamping depth indicated on the milling cutter shank. If the marking on older milling cutters is no longer recognisable, clamp ¾ of the shank length in the collet. Observing the clamping depth is important for safety reasons to prevent the cutter shank from breaking off. In addition, milling cutters require high concentricity and a high clamping effect of the collet chuck. If router shanks are not clamped deep enough, the concentricity may deteriorate and the collet may come loose.
Max. speed permissible
Observe the recommended maximum Speed indicated on the milling shaft. The recommended Speed depends on the milling head Diameter:

Milling cutter groups
We offer a selection of different milling cutters, which are divided into the following groups and areas of application.
Profile cutters:
Different profile variants, mostly for decorative purposes. Many Profile cutters have a thrust ball bearing and are used for edge processing. These include Rounding cutters, Hollow bevel cutters, Chamfer cutters, Bull nose cutters etc.
Script cutters:
Also known as V-groove cutters. Available with different angles, e.g. 90°, 60°. For milling decorative grooves, small chamfers or for creating lettering or graphics.
Groove cutters:
Usually available as carbide-tipped milling cutters or solid carbide milling cutters (also known as spiral flute milling cutters if they have a spiral flute). With groove-cutting machines, it is important to note whether they are also used for drilling (i.e. plunging into the material) or only for grooving (positioning the cutter on the edge of the workpiece). Groove-cutting machines without a so-called drill cutting edge are not suitable for plunging into the material. The specification Z2 refers to a groove-cutting machines with two main cutting edges (without drilling edge). The specification Z2+1 refers to a milling cutter with 2 main cutting edges and an additional drilling edge.
Dovetail milling cutter:
Also known as tine or burr cutters. They are used for the production of a burr joint (burr groove and burr moulding) or for milling a carcass joint with dovetail cutters.
Flush trimming cutters and Copy milling cutters:
These are milling cutters with a cylindrical milling head, similar to groove-cutting machines. However, the milling cutter has one or two ball bearings. The ball bearings serve as a cutting depth limiter (for Flush trimming cutters) or as a thrust ring (for Copy milling cutters), which scans a template along a template edge. The ball bearings can be mounted either on the cutting edge or on the shaft or on both sides.
Groove-cutting machines:
For milling out T-slots in a single operation. Two different diameters create the typical T-shape for sliding hexagon bolts or sliding blocks. Also suitable for milling out keyhole hangers.
