The Anatomy of an End Mill - In The Loupe

10/12/2017 · End Mill Helix Angle. The helix angle of a tool is measured by the angle formed between the centerline of the tool and a straight line tangent along the cutting edge. A higher helix angle used for finishing (45°, for example) wraps around the tool faster and makes for a more aggressive cut. A lower helix angle (35°) wraps slower and would have a stronger cutting

17/11/2015 · On an end mill with a 30 degree helix angle, 25 % of the force is axial and 75 % radial. On a 45 deg. helix angle, the forces are divided equally, 50 % radial and 50 % axial. High helix cutters have an helix angle of 60 deg. At a higher helix angle the radial forces are lower and cutting is smoother, vibrations lower. Surface finish and chip evacuation are better. The cutter

Non-centre cutting end mills refers to those that mill, they do not drill. (they have cutting edges only on the sides) Up-cut end mills eject chips towards the top of the workpiece, leaving a cleanly cut bottom surface inside your material. Down-cut end mills do the opposite, they leave a smooth top surface on your material.
