This guide introduces the most common CNC cutting tools used in metal machining and explains their functions and best practices. It covers chamfer cutters for edge finishing, center drills for accurate hole positioning, reamers for precision hole sizing, taps for internal threading, and twist drills for general hole-making. Each section includes practical usage tips to improve machining accuracy, tool life, and overall production quality.

This guide introduces the most widely used CNC milling cutters and their key applications in rapid prototyping and custom manufacturing. It covers flat end mills for sharp edges and pockets, ball end mills for curved surfaces, bull-nose cutters for durable 3D roughing, face mills for fast material removal, T-slot cutters for undercuts, and keyseat cutters for precision keyways. Selecting the right cutter directly enhances machining accuracy, surface finish, and efficiency—cru
