Precision CNC Milling Bit for Plastics, Acrylics & Soft Woods
The Maxmake 1-Flute Flat Mill 2.5mm x 12mm is a premium quality solid carbide O-Flute CNC router bit designed for smooth, accurate, and reliable cutting. Because of its ultra sharp cutting edge and mirror polished flute, this single flute end mill delivers clean finishes while also improving chip evacuation during every cut.
This CNC flat mill is designed specifically for the MaxMake HiMill D1 CNC Machine and the MaxMake HiMill D1S CNC Machine. Therefore, it works perfectly for makers, hobby users, schools, workshops, and professional CNC users who need dependable cutting performance.
In addition, the 1-flute up-cut design reduces heat build-up while helping prevent melting and clogging when machining plastics and acrylic materials.
Key Features of the Maxmake 1-Flute CNC End Mill
Premium Solid Carbide Construction
This solid carbide CNC bit offers excellent rigidity and durability. As a result, you get cleaner cuts, better stability, and extended tool life.
Ultra Sharp O-Flute Cutting Edge
The ultra sharp edge allows smoother cutting while also reducing resistance during operation. Therefore, your CNC machine can produce cleaner edges with less stress on the spindle.
Mirror Polished Flute Design
The polished flute improves chip removal and keeps waste moving away from the cutting area. Consequently, this helps prevent clogging and improves surface finish quality.
Up-Cut Spiral End Mill Design
The up-cut spiral design lifts chips upward efficiently. Because of this, the bit performs extremely well on plastics, acrylic sheets, ABS, and soft woods.
Extended Tool Life
The durable carbide structure and efficient flute geometry help reduce wear over time. Therefore, users can achieve consistent cutting performance across longer production runs.
Best Materials for This CNC Router Bit
This 1-flute flat mill is ideal for:
- Acrylic
- ABS
- PVC
- Plastics
- Foam board
- MDF
- Soft wood
- Composite boards
- Non-metallic materials
Because the bit is designed for non-metallic machining, it produces excellent finishes on softer materials while also helping reduce melting and edge chipping.
Materials NOT Compatible With This Bit
This O-Flute end mill is NOT recommended for:
- Stainless steel
- Hardened steel
- Carbon steel
- Titanium
- Iron
- Stone
