Maxmake 1-Flute Flat Mill 3.175mm x 22mm (1pk) – O-Flute CNC Router Bit for HiMill D1 & D1S
Precision CNC Milling Bit for HiMill D1 and HiMill D1S CNC Machines
The Maxmake 1-Flute Flat Mill 3.175mm x 22mm is designed specifically for smooth, accurate and reliable CNC cutting on the Maxmake HiMill D1 and HiMill D1S CNC Machines. Because this premium O-Flute CNC router bitfeatures a sharp single flute design, it delivers cleaner cuts, faster chip removal and a smoother finish on non-metallic materials.
In addition, the polished flute design helps prevent heat build-up. Therefore, materials stay cleaner while the cutter stays sharper for longer. As a result, this solid carbide CNC end mill is perfect for makers, hobby users and professional CNC operators who want dependable cutting performance every time.
This 1/8″ shank CNC bit fits perfectly with compatible CNC collets used on the Maxmake HiMill range. Consequently, setup stays simple and cutting remains stable even during longer jobs.
Premium Solid Carbide O-Flute End Mill Features
Solid Carbide CNC Router Bit Construction
- Premium solid carbide construction
- Ultra sharp cutting edge
- Extended tool life
- Excellent wear resistance
- Stable and smooth CNC cutting
Mirror Polished O-Flute Design
The mirror polished flute design improves chip evacuation while also reducing clogging. Therefore, acrylics and plastics cut cleaner with less melting or edge marking.
Single Flute CNC Bit for Faster Chip Removal
Because the cutter uses a single flute up-cut spiral design, chips clear quickly and efficiently. In turn, this allows cleaner cuts at higher feed rates.
Best Materials for the Maxmake 1-Flute Flat Mill
This single flute CNC router bit works best with non-metallic materials including:
