It is the angle between face of the tool and a plane perpendicular to the side of the shank.It varies from 5 to 15 degrees.
The shear angle in machining and manufacturing processes serves to optimize cutting efficiency by determining the relationship between the cutting edge and the workpiece material. It influences the forces acting on the tool, affecting tool life and surface finish. Additionally, the shear angle helps in controlling the thickness of the chip being formed, which can impact the energy required for cutting and overall productivity. Adjusting the shear angle can also enhance the stability of the cutting process and reduce vibrations.
these are tools which have teeth in the edge were it's use for cutting
A chisel size is the width of the cutting edge.
1. cutting tool should be more harder than the material to be cut otherwise it can break during the process. 2.cutting tool should be tough.well,there is much difference between the word hard and tough. hardness implies resistance to scratch whereas toughness measure ability to withstand shock. 3.The tool should be able to withstand the heat generated in the metal cutting process. Also, the tool must have a specific geometry, designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the surface of the piece part surface. The angle of the cutting face is also importantol must be able to withstand the heat generated in the metal cutting process. The angle of the cutting face is also important as is the flute width, tool margin and tool material. SUGGESTIONS ARE WELCOME

"the cutting edge "
The proper angle for the edge of a cold chisel is typically around 60 to 70 degrees. This angle helps to ensure that the chisel is sharp and effective for cutting and shaping materials.
The parts of a twist drill include the shank, neck, flutes, land, body clearance, and cutting edge. The cutting edge is the point of the drill bit and does the actual cutting.
The edge of a shape can be considered a point where two sides meet to either form an angle (inside) or edge (outside).
Approach angle in metal cutting refers to the angle formed between the cutting edge of the tool and the workpiece surface. It determines how the tool engages with the material during cutting and has an impact on cutting forces, tool life, and surface finish. A proper approach angle is important for efficient and effective metal cutting operations.
One cutting edge vs two
On a blade, the cutting edge is the sharp side.
The duration of The Cutting Edge is 1.62 hours.
A drop point blade has a convex curve of the back, the opposite side of the cutting edge, towards the point.
The clear difference between positive and negative rake angles is that for the positive rake angle,the leading edge of the cutting tool is behind the perpendicular of the material to be cut.While the tool leading edge is ahead or beyond the perpendicular for the negative rake angle.
