ER11 Collet Set

Fir Fir is easy to work with and has consistent patterns in the wood. It’s a good option for handling hardwood purposes such as flooring and furniture due to its characteristic durability.

Maple Maple is one of the hardest woods. It’s particularly beneficial for its density, durability and resistance to electrical shocks. Therefore, maple is a perfect choice for something that will take a few knocks, such as workstations or heavy-duty chopping boards.

We believe the best wood for CNC sign making is cypress due to its incredibly soft density. If you haven’t yet tried to make a sign with your CNC machine, start experimenting. It’s a fun and stress-free project that serves a purpose for the home or work.

For that reason, we denote our collet grades with a TIR specified at the collet face (TIRF) AND at a point 1" down the calibration blank (TIR1") as shown in the image on the left. These values are listed in the table on the right.

When it comes to CNC routing, there are numerous woods to choose from that can be distinguished between hardwood and softwood:

Yew A straight grain makes Yew easier to work with. It’s particularly hard despite being considered a softwood variant. A signature resistance to decay combines with low stiffness and medium strength.

Cherry Cherry boasts a stunning finish with beautiful reddish-brown tones. It’s especially resistant to warping. Cherrywood is a very versatile material too. It’s suitable for all types of CNC projects, from furniture to musical instruments. Its natural radiant tone and smooth finish make it particularly pleasing to the eye.

Pine Pine is a very lightweight wood of a paler colour and is more resistant to shrinking due to its surprising hardness.

At Midlands CNC, we’ve specialised in CNC machining and routing. If you’re looking to cut costs or want to know what wood type to choose, get in touch. We can offer our expertise for your choice of wood, alongside any guidance or support throughout the process, from design to finish.

Basswood is one of the best wood materials for engraving due to its strong yet soft and lightweight nature. No matter the level of detail involved in your desired engraving, a CNC machine can produce incredible results in the most intricate designs.

Birch Birchwood is light in colour with wavy grains and is as hard as oak or walnut. Its characteristic properties of being resistant to chips and dents make it the ideal wood choice for CNC routing. It also holds screws very well, offering an excellent brace option or structural component when constructing furniture.

Oak Oak is hard, strong, and heavy with unique pronounced rings in the grain. It’s a great option for outdoor projects due to its moisture resistance, such as garden furniture or shipbuilding.

Cedar Popular for its reddish-brown colouring and pleasant aroma, cedarwood is weather-resistant like oak and ideal for outside furniture.

Cypress Excellent decay resistance and remarkably soft to work with, cypress is a popular softwood choice for CNC furniture projects, such as cabinets and wardrobes.

Ash Ash is notoriously a heavy wood but comes light in colour with signature rings within the grain. Due to its characteristic properties of hardness and stiffness, it’s perfect for CNC routing projects, such as:

The measurement reported is generally the one taken at the 4 X D point on the blank. No mention is made of the other measurement, or the phase angle between them. Without these 2 pieces of infomation, there is no way to determine what the TIR will be farther from the collet face. It may not souund like much of a problem but, if the two measurements are exactly 180° out of phase, a tool clamped in the collet will be skewed across the central axis with the TIR increasing the farther you get from the crossing point. For collets used with microtools (like ours), it is more important to know how the tool is "wobbling" at the length where it is actually cutting. For 1/8" shank bits with an overall length of 1-1/2", this is typically about 1" from the collet face.

Walnut Durable with darker brown tones and signature straight grains away from the roots, walnut takes shocks particularly well and is a favourite material amongst carpenters and sculptures.

CNC 3D carving is the next level of craftsmanship which requires wood that doesn’t tear very easily and provides a nice smooth finish. It’s also important to use some wood with consistent grain due to the varying cuts involved during the process.

When it comes to CNC routing and 3D carving, you can use multiple types of wood. But which material best suits your needs and why? To give you a better idea, we’ve compiled a summary of what different wood types accommodate various levels of CNC experience and purposes.

Beech Beechwood is renowned for its strength and hardness, making it another suitable option for tables and chairs. As an odourless wood, it’s spot on for kitchen equipment, such as cutlery, plates and cutting boards.

Generally speaking, collet manufactures specify a single value for the runout (TIR) of a collet. Often it is not clear where, relative to the collet face, the measurement was made. International standards for ER style spring collets (DIN6499 and ISO15488) specify that the TIR of a collet should be determined at the collet face and at a distance not less than 4 times the clamping diameter (D). For example, the TIR of a collet with a clamping diameter of 1/8" (3.18mm) should be measured as close to the face as possible and at a distance not less than 4 X 1/8" = 1/2" (12.7mm) along a certified precision calibration blank.

What’s the Best Wood for CNC Machining Beginners? Firstly, as a beginner in CNC machining, you will want to purchase your wood cheaply. Cheaper wood grants you the freedom to practice your CNC craft before designing and establishing finished projects you can sell, display or use. The price of wood depends on your location. For example, wood that is available locally will prove much cheaper to buy. We also recommend using wood that’s easy to carve, such as:
