6 Points You Should Consider When Choosing Wood Milling Cutter

When we DIY something, we use wood milling cutters(router bits) to mill or shape our wooden board, which can make our work piece looks better. For old hands, to choose a appropriate tool for their work piece is not a hard thing. Things about woodworking tools have been engraved on their memories. But for beginners, it is not a easy thing to choose a right router bit. So we collected 6 tips for beginners about how to choose right wood milling cutters for their work pieces.

router bits

1.Determine main technical parameters

We may call all kinds of trees timbers after they are been cut into pieces, but it doesn’t mean there are no differences in wood materials. Some wood boards are harder when some are softer, and some wooden boards are mixed with too much glue which may easily make your tools get black or go wrong. So, to deal with wood with different property, we have to choose specific tools. To choose right wood milling cutter for your tool, you need to know some basic parameters first. There are main parameters such as cutter diameter, cutting thickness and diameter of central aperture. Also, there are other parameters like teeth number, rotation direction, rotation velocity, feeding velocity, clamping method, material of blade teeth. Know these parameters of bits, you can know how to choose a suitable tool for your routers and work pieces.

2.Structure of router bit

Totally speaking, we have mainly four types of wood milling cutters structure. They are solid wood milling cutters, welded solid wood milling cutters, assembly wood milling cutters and interlocked wood milling cutters. Structure of your bits is connected to property of cutting objects. So, select right structure for your bits according to nature and requirements of cutting objects.Considering bothtechnical and economic aspects,then you could decide to choose solid wood milling cutters,welded solid wood milling cutters, assembly wood milling cuttersor interlocked wood milling cutters.

3.Influence of rotation direction

Rotation direction is based on machine spindle rotation directionand determined by relative position of cutter shaft and workpiece.No matter it issolid bit, or assemblybits, the dip angle between cutting edge andradius of wood milling cutters determinerotation direction.

4.Cutting parameters

Cutting parameter include cutting speed of yourcutter, feed velocityand depthof cutting.Cutting speed depends on milling speed and radius ofyour bits.Feed velocitydepends on quality of cutting surface.Surface roughness of yourworkpiece is largely determined by milling process of each tooth feed. If feed volume is too large, processing surface is too roughorper tooth feed is too small, there will be burning marks on processing surfaces of your work piece,so feed volume of per tooth ofyourbitmust be appropriateto actual processing situation.

5.Operation stability

Stability of milling cutter operation is the basis of machining precision and surface quality.Stability is mainly influenced bytwo aspects: one is vibration which is caused duringcutting process due to external force. Second, deformation of milling cutter occurs under the influence ofexternal forces.

6.Operation Safety

Safety of milling includes rotation velocitylimitation, chip thickness limitation, height limitationof shaper cutters’profile, thickness limit of assembly wood milling cuttersand length of extended parts of blades.
High speed cutting is one of the biggest characteristics of wood milling cutters. General rotation velocityofbitsis more than 3000rpm. High speed cutting brings high production efficiency and smooth surface quality for wood cutting.However, at the same time, high speed cutting also brought a series of safety problems. So whenspeed ofmilling machine spindle reaches 9000rpm, assembly wood milling cutters should be prohibited except shank milling cutter which is shorter than 16mm.Even for welding seam of whole milling cutter also need to carryout strict flaw detection inspection.Chip thickness limitation is a necessary measure to prevent milling cutters from overload due to excessive feed.


You may still think choosing a right router bit for yourself is not an easy thing, but at least now we know what we should learn before purchasing ourselves wood milling cutters. Except tips above, there are also other things you need to concern. For example, materials of your bits. We usually use carbide tipped wood milling cutters for routing wooden boards, but there are also other materials such as high speed steel situation. So actual situation should still be decided by materials of your work pieces.
Finally, if you have any demands in wood milling cutters, you may be interested in our products. We have all kinds of wood milling cutters(carbide tipped wood milling cutters, solid carbide wood milling cutters, compression wood milling cutters,etc.) for hand router, table router and even for CNC machine. Except bits we listed, we can also do customization. Tell us your demands or send us e-mail, we can customize one for you.
