1. Definition:

Regrinding involves reshaping and sharpening worn-out cutting tools to restore their performance. Over time, tools used in machining processes like milling, drilling, and cutting become dull due to wear. Instead of replacing these tools, they can be reground to extend their usability. Regrinding is a cost-effective method to maintain productivity while minimizing tool expenses.

2. Types of Tools that Can Be Reground:

• End Mills: Used in milling operations, end mills can be reground to restore their cutting edges and flute profiles.
• Drills: Worn drill bits can be reground to renew their tips and improve cutting accuracy and efficiency.
• Reamers: Reamers used for precision hole finishing can be reground to maintain their dimensional accuracy.
• Carbide Inserts: Carbide inserts used in various machining operations can be reground, saving the cost of buying new inserts.
• Saw Blades: Regrinding restores the sharpness of saw blades used in wood and metal cutting.
• Router Bits: Used in woodworking, these tools can be reground to maintain smooth and precise cuts.
