FAQ
Q: What is a spot drill used for?
A: Spot drill is mainly used to make a small indentation on the workpiece. It can fix the position of the hole, stop the twist drill from slipping, and finish chamfering at the same time.
Q: What coatings do you provide?
A: We supply TiN, TiSiN and uncoated versions. Coated drills have better wear resistance for hard metal cutting.
Q: Can I get custom sizes?
A: Custom diameters, lengths and point angles are available upon request. Please send your detailed drawing or machining requirements.
Q: Which materials can this spot drill machine?
A: It can process steel, stainless steel, aluminum alloy and cast iron. You can choose the corresponding coating according to your workpiece.
