Milling Cutters

The milling cutters may have straight teeth i.e. parallel to the rotation axis 

or in helical shape. 

The angle of helix may be right hand or left hand which will decide the direction rotation of the cutter for cutting operation.  

A milling cutter may be made of single piece of steel ot having cutting teeth inserted solid body. 

According to the shape of teeth, milling teeth are broadly classified as follows

1.   Plain milling cutters

 Light duty cutters, Heavy duty cutters, Helical cutters

2. Side milling cutters

 Plain cutters,  staggered teeth cutters,   Half cutters,  Interlocking cutters

3. Metal slitting cutters

 Plain cutters,  staggered teeth cutters

4. End milling cutters 

Taper shank cutters, Straight shank cutters, Shell cutters

5. T-slot milling cutters

6. Woodruff key slot milling cutters

  7. Fly cutters

8. Angle milling cutters 

Single angle cutter, Double angle cutters

9. Formed milling cutters

Convex milling cutters,  Concave milling cutters, Corner rounding milling cutters, Concave milling cutters, Gear cutters,  Thread milling cutter

Plain milling cutters

 Plain milling cutters are cylindrical in shape and have the cutting teeth on their periphery. The cutting teeth may be either straight or helical.  Their end faces are either ground square with the axis or slightly concave to reduce the friction.  Hence, by side faces no cutting action is provided. These cutters are used for milling flat surfaces parallel to the rotation axis. These cutters are available in diameters from 16 to 160 mm and width range from 20 to 160 mm. The different types of plain milling cutters are as follows :

(a)  Light duty plain milling cutters 

These cutters are available upto 20 mm width and carry straight teeth.
