Alloy centering drill bit

Alloy centering drill bitFunction: (Point hole, hole chamfer, border chamfer, point hole and chamfer completed in one go)

Alloy centering drill bitThe shape is short and thick, with a short chip groove and excellent rigidity. The alloy centering drill has a good effect. Its drill tip geometry is just enough to drill a shallow hole on the surface of the workpiece; Compared with standard drill bits, the transverse edge of the centering drill is very thin, which can effectively cut the workpiece material.

The centering drill is also constantly developing and changing, and its function is no longer limited to drilling centering holes. For example, edge milling and drilling can also be performedmilling cutterIntegrated, the angle can also be 60 °, 90 °, 118 °, 135 °, 140 °, etc., which can be used for various processing: drilling centering holes, holes, engraving, chamfering, and removing edge burrs, etc.

Centering drills can also be used to machine chamfered holes before formal drilling. By controlling the drilling depth of the centering drill, the required chamfer aperture can be formed while determining the hole position. You can create a centering hole for secondary drilling in the same step, while forming a chamfer at the hole opening. By slightly increasing the centering drilling depth, a larger aperture can be formed than the diameter of the secondary drill bit. In this way, when you drill with a slightly smaller diameter secondary drill bit, you can obtain a larger diameter chamfer at the hole opening.
