Drill Chisel Edge at Olivia Breillat blog

Drill Chisel Edge. The lips are the primary cutting edges of the drill. The chisel edge, which connects the cutting lips, is ground at an angle and handles more than half of the axial. Of the drill point—is the chisel edge. The rake angle of the cutting edge of a drill reduces toward the centre, and it changes into a negative angle at the chisel edge. The web is the central portion of the drill body that connects the lands. It connects the cutting lips. High machining accuracy and finished surface roughness. Point angle, main cutting edge, cut chisel edge, point cut and point thinning, profile. The cutting edge is ground radial with the aim of dispersing load. Let's take a look at the eight basic features of a twist drill: Both cutting edges are sharpened at the same angle, so each makes angle of 59° to the center axis. It is the angle included between the chisel edge and lip of the twist drill when measuring on a plane normal to the axis. They extend from the chisel point to the periphery of the drill. When drilling a hole, the chisel's full length contacts metal and the chisel's corners simultaneously augurs into the metal,. The edge ground on the tool point along the web is called the chisel edge.
