CNC Cutting Bit Guide

If you have just bought a CNC or are in the market for our Cron Craft CNC, choosing the correct cutting bits probably ranks second after choosing a machine size. Here at the 3D Printing Store, we have a wide variety of cutting bits for you to choose from. 

Let's have a look at some of the cutting bits we have in store.

Fish Tail PCB Cutting Bit

The Fish Tail PCB End Mill for milling of PCBs, wood, plastic and foam.  This is a general purpose milling bit That can be used on a wide variety of materials.

Specifications:

  • Cutter type: Fish Tail PCB End Mill
  • Material: Tungsten Cobalt Alloy
  • Cutter diameter: 0.6mm, 0.8mm, 1mm, 1.5mm, 2mm, 2.5mm or 3mm (Please choose from the menu above)
  • Cutter length: 10mm
  • Shaft diameter: 3.175mm (1/8 inch)
  • Shaft length: 22mm
  • Total Length: 38mm

V-cutting Bit

V-Cutting Bit for engraving of wood, plastic aluminium and PCBs.  This is a general purpose engraving bit.

Specifications:

  • Cutter type: V-Cutting bit
  • V-Cutter Angle: 20, 30, 45, 60, 90 Degrees (Please choose from the menu above)
  • Knife Tip Width: 0.1mm
  • Shank diameter: 3.175mm (1/8 inch)
  • Total length: 30mm
  • Quantity: 10 pieces (Pack of 10)

Single Flute Cutting Bit

Single Flute tungsten carbide end mill to cut a wide variety of materials.  The single flute allows more material to be removed per revolution of the bit which is good for materials like aluminium and plastics.  It also allows spindles which do not have a low speed setting, to cut material more effectively.  

Specifications:

  • Material: Tungsten Carbide
  • Diameter: 1mm, 1.5mm, 2mm, 2.5mm, 3.175mm, 4mm, 6mm (Please select from the menu above)
  • Shank Diameter: 3.175mm (1/8')
  • Materials to cut: Wood, Plastic, Aluminium, Brass, Composites, Cardboard and Structural foam
  • Cutting Edge Length for 1mm bit: 4mm
  • Cutting Edge Length for 1.5mm bit: 6mm
  • Cutting Edge Length for 2mm bit: 8mm
  • Cutting Edge Length for 2.5mm bit: 12mm
  • Cutting Edge Length for 3.175mm bit: 25mm
  • Cutting Edge Length for 4mm bit: 10mm (Shank Diameter: 4mm)
  • Cutting Edge Length for 6mm bit: 15mm (Shank Diameter: 6mm)

Double Flute End Mill Cutting Bit

Double Flute tungsten carbide end mill to cut a wide variety of materials.  A double flute cutter has a flat bottom end which creates a smooth bottom surface.  The low flute count also work better with materials which is sensitive to heat generated by the cutting bit, like plastics.  

Specifications:

  • Bit Type: Double flute end mill cutter
  • Material: Tungsten Carbide
  • Diameter: 1mm, 1.5mm, 2mm, 2.5mm, 3.175mm, 4mm, 6mm (Please select from the menu above)
  • Materials to cut: Wood, Plastic, Aluminium, Brass, Composites, Cardboard and Structural foam
  •  Cutting Edge Length:
  • For 1mm bit: 6mm
  • For 1.5mm bit: 8mm
  • For 2mm bit: 12mm
  • For 2.5mm bit: 15mm
  • For 3.175mm bit: 22mm
  • For 4mm bit: 10mm
  • For 6mm bit: 15mm
  • Shank Diameter:
  • For 1mm bit: 3.175mm (1/8')
  • For 1.5mm bit: 3.175mm (1/8')
  • For 2mm bit: 3.175mm (1/8')
  • For 2.5mm bit: 3.175mm (1/8')
  • For 3.175mm bit: 3.175mm (1/8')
  • For 4mm bit: 4mm
  • For 6mm bit: 6mm
  • Cutting bit total length:
  • 1mm to 2.5mm: 38mm
  • 3.175mm, 4mm & 6mm: 45mm

Double Flute Down Cutting Bit

Double Flute tungsten carbide down cutting bit to cut a wide variety of materials.  A down cutter is used to push the material being cut down onto the cutting bed to assist with keeping the material in place.  The other advantage of a down cutter is that less dust is produced, because the material being removed is pushed down.  The low flute count also work better with materials which is sensitive to heat generated by the cutting bit, like plastics.  These bits are widely used to do profile cutting of wood or plastic materials.

Specifications:

  • Bit Type: Double flute down cutter
  • Material: Tungsten Carbide
  • Diameter: 3.175mm, 4mm, 6mm (Please select from the menu above)
  • Materials to cut: Wood, Plastic, Aluminium, Brass, Composites, Cardboard and Structural foam
  • Cutting Edge Length:
  • For 3.175mm bit: 22mm
  • For 4mm bit: 22mm
  • For 6mm bit: 22mm
  • Shank Diameter:
  • For 3.175mm bit: 3.175mm (1/8')
  • For 4mm bit: 4mm
  • For 6mm bit: 6mm
  • Cutting bit total length:
  • 3.175mm & 4mm: 45mm
  • 6mm: 50mm 

Ball Nose Cutter

Ball Nose Cutter for 3D carving of wood, plastic, aluminium and foam.  The Ball nose cutter enables carving of 3D surfaces.

Specifications:

  • Cutter type: Ball Nose Cutter
  • Material: Tungsten Carbide
  • Ball radius: 0.5mm, 1mm, 1.5mm, 2mm (Please choose from the menu above)
  • Number of Flutes: 2 
  • Shank diameter: 4mm
  • Total length: 50mm
  • Quantity: 1 piece

Skimming Bit

Skimming bits are used to plane large surfaces like the bed of a CNC machine or to cut out big pockets in wood or plastic. 

Specifications:

  • Bit Type: Skimming Bit
  • Diameter: 16mm
  • Materials to cut: Wood, Plastic and Structural foam
  • Shaft diameter: 6mm
  • Bit total length: 44mm

V-Curving Bit

V-Carving bits are used to cut a 2D image so that it created a 3D effect.  The 3D effect comes from the fact that the bit cuts deeper where the image is wider and shallower where the image is narrow. The difference in depth creates the 3D effect.

The other application of these bits are to chamfer the edge of a workpiece.

Specifications:

  • Bit Type: V-Carving bit
  • Diameter: 32mm
  • V Angle: 60 Degree, 90 Degree or 120 Degree (Please select from the menu above)
  • Materials to cut: Wood, Plastic and Structural foam
  • Shaft diameter: 6mm

Here is a nice bit guide to help you choose the perfect bit for you.
