<b>Precautions </b> Make sure the MDF spoilboard is secured well to the machine bed.<br> Make sure the CNC material is clamped tight to the MDF spoilboard/machine bed, or you will get vibration, chatter, poor cut finish, and can possibly break your cutting bit. <br> Do not use any lubricant when you use an MDF spoilboard. It will swell and expand if it gets wet. So using spray or mist coolant or oils is not recommended.<br> <br> <b>Specification</b><br> Material: MDF<br> Spoilboard Size: 30cm x 18cm x 1.2cm (11-4/5''x 7''x 1/2'')<br>Hole Diameter: 6mm<br><br> <b>Package List:</b><br> 1 x MDF Spoilborad<br>
