Hss Twist Drill Bit Din341 Din1870 - Chinaprice: contact company for price
The twist drill is the most common type of drill. The shank
of the drill is held by the machine tool, which in turn
imparts a rotary motion. This shank may be straight or
tapered. The body of the drill is typically made up of two
spiral grooves known as flutes, which are defined by a helix
angle that is generally about 30 degree but can vary
depending on the material properties of the workpiece. The
point of the drill generally form a 118° angle and includes
a 10 degree clearance angle and chisel edge .The chisel edge
is flat with web thickness of approximately 0.015 x drill
diameter. This edge can cause problems in hole location
owing to its ability to "walk" on a surface before engaging
the workpiece. In the case of brittle materials, drill point
angles of less than 118 are used, while ductile materials
use larger points angles and smaller clearance angles.
These drill bits can be used in wood, metal, plastic, and
most other materials.
