Carbide spotting drill is a type of cutting tool used in metalworking to create a small, shallow hole in a workpiece before drilling a larger hole.
It is typically made of solid carbide, which is a very hard and durable material that can withstand high temperatures and wear.
The spotting drill has a pointed tip that is used to accurately locate the center of the hole and create a small indentation or "spot" for the larger drill bit to follow.
This helps to ensure that the larger hole is drilled accurately and without wandering or drifting off center.
Carbide spotting drills are commonly used in precision machining applications, such as aerospace and medical device manufacturing, where accuracy and consistency are critical.
