Maxmake 1-Flute Flat Mill 3.175mm x 12mm (1pk) – O-Flute CNC Router Bit for HiMill D1 & D1S
Premium 1-Flute CNC Flat Mill for Acrylic, Plastics & Soft Wood
The Maxmake 1-Flute Flat Mill 3.175mm x 12mm delivers smooth, accurate, and reliable CNC cutting for makers, hobbyists, and professionals. Designed specifically for the Maxmake HiMill D1 and HiMill D1S CNC Machines, this premium O-Flute Up-Cut Spiral End Mill provides excellent chip removal while also creating cleaner edges and smoother finishes.
Because this bit uses a single flute design, it clears chips quickly and efficiently. As a result, heat build-up stays low and materials cut cleaner with less melting or clogging. In addition, the mirror polished flute design improves chip evacuation even further, which helps maintain accuracy during longer CNC jobs.
Whether you are cutting acrylic, ABS, plastics, or soft wood, this 3.175mm CNC router bit gives fast and consistent results every time.
Designed for the Maxmake HiMill D1 & HiMill D1S CNC Machines
This 1/8″ shank CNC end mill works perfectly with the following machines:
- Maxmake HiMill D1 CNC Machine
- Maxmake HiMill D1S CNC Machine
- Maxmake CNC Router Bits
Thanks to its balanced design and ultra sharp cutting edge, this solid carbide CNC bit supports high feed rates while still maintaining excellent surface quality. Therefore, it is ideal for both detailed work and faster production cutting.
Premium Solid Carbide CNC Router Bit Features
Solid Carbide Construction
This solid carbide single flute end mill offers excellent rigidity and durability. As a result, tool wear reduces while cutting precision improves.
Ultra Sharp Cutting Edge
The sharp edge cuts smoothly through non-metal materials. Therefore, you achieve cleaner cuts with reduced burrs and improved finish quality.
Mirror Polished Flute Design
The polished flute helps chips evacuate quickly. In turn, this reduces clogging, lowers heat, and prevents material melting during long CNC jobs.
Extended Tool Life
Because the bit uses premium carbide materials, it stays sharper for longer. Therefore, you spend less time changing tools and more time machining.
Up-Cut Spiral Geometry
The up-cut design lifts chips away from the cutting area. Consequently, cuts remain cleaner and more accurate throughout the job.
Best Materials for This O-Flute CNC End Mill
This O-Flute CNC router bit is designed mainly for non-metallic materials, including:
- Acrylic
- ABS
- PVC
- Plastics
- Foam board
- MDF
- Soft woods
- Composite boards
In particular, it performs extremely well when machining acrylic because the polished flute helps reduce melting while improving edge finish.
