More Info

These tools are designed to process most types of rigid plastic materials, such as acrylic, polycarbonate, PVC, nylon, etc. They are also effective for use on woods and foams. The upward spiral geometry ejects swarf and dust toward the top of the cutter, making waste material removal easy with a suitable extraction system. During cutting, the spiral flute tends to lift the material so a good workholding system is important to eliminate any movement or vibration which can cause inaccuracy and poor cut quality.


These cutters are specially manufactured for CNCRoutershop to provide a versatile, low-cost tool suitable for a wide range of applications.

Recommended for

  • All types of rigid plastic materials such as acrylic, ABS, PVC, polycarbonate and acetal

  • Woods including MDF, plywood, chipboard and all natural hard and soft woods

  • Foam

AXYZ recommends wherever possible the use of tools specifically designed for each material and application.

Feeds and Speeds

Typical settings for the 6mm (2011J-6) tool profile cutting acrylic are:

Feed rate: Approx 3m/min

Spindle rpm: 22,000 - 24,000

Max cut depth: 4 - 6mm

NOTE: These values should be used for guidance only. Under most conditions, they will be a reliable starting point. With experience, you may well find that they can be improved to better suit specific machining applications.

Maintenance Tips

Although these tools are very hard and wear resistant, they are susceptible to damage caused by careless handling. Always store tools in individual packaging to avoid damage caused by contact with other tooling. Even a very small chip in the cutting edge will cause unwanted marks on the workpiece and lead to faster tool wear.
