Final answer:
The bevel angle of a chisel blade is typically between 25° and 30°, providing a balance of sharpness for cutting and durability for impact.
Step-by-step explanation:
The blade, or iron, of the chisel is a flat steel bar that is beveled on the end at what angle? The correct answer is a. 25° to 30°.
Chisels are an important tool in woodworking and metalworking. The angle of the bevel on the chisel's blade is significant because it determines the sharpness and strength of the cutting edge. A common bevel angle for a chisel is between 25° and 30°. This angle offers a good balance between a sharp edge for cutting and durability for withstanding the impact of carving or chiseling.
