2 Flute STRAIGHT cutter carbide CNC router bit is a popular choice among "decor warriors" who work with MDF and plywood. These mills have straight blades that make them suitable for cutting a variety of timber materials, such as plywood, melamine chipboard, whiteboard, and veneers. They are also cost-effective compared to other types of end mills, like down and compression cutters, and provide a good finish on both sides of the material.

Adam’s Tips
A straight flute end mill is a useful tool for cutting a variety of materials, but it does create a significant amount of dust as opposed to chips. Therefore, it is important to have proper ventilation or dust extraction in place to ensure a safe and healthy working environment. One benefit of this dust is that it gets packed back into the slot made by the end mill, which can help to hold the material in place. This eliminates the need to use tabs or tape to secure the material and can save time on handling. However, it's also important to keep in mind that the dust created is fine particulates which can be harmful to health, it's highly recommend to make sure the dust created is disposed off properly and safely.

Frequently asked questions
What is a 2 flute straight bit best for?
An economical all-rounder for cutting MDF and plywood parts with clean faces top and bottom. The straight (zero-helix) flutes neither lift nor push the sheet.
Which diameter suits my material thickness?
Popular choices: 1mm for 3mm material, 1.5mm for 6mm, 2mm for 17mm and 3.175mm (1/8") for 18mm material.
Does it make dust or chips?
Mostly fine dust rather than chips. Use dust extraction or good ventilation, and a light brush cleans up any small burrs.
Straight, up cut, down cut or compression?
The straight bit is the cheapest and gives an acceptable finish on both faces. Compression gives the best finish on both faces, down cut the cleanest top, and up cut the cleanest bottom with the best chip clearance.
