10 Pieces Mini Carbide Drill Bits, High Hardness 0.25mm Mini High Hardness for CNC Engraving of Printed Circuit Boards (0.25MM)

1. Large chip removal area - Low chip resistance, smooth chip removal, low heat generation.

2. Excellent cutting edge sharpness - Thanks to advanced grinding technology, the drill bit cutting edge is sharper than before, which can reduce cutting force, lower the drilling rate, and improve quality. 3. Tool design based on customer needs - A wide variety of drill bits to meet different application needs. Drill bit parameters, such as core thickness and core taper, have been carefully designed for efficiency. 4. Strictly symmetrical cutting edge - This is beneficial for efficient cutting and prevents drilling misalignment. 5. Processing range - Printed circuit board, SMT, CNC, mold making, engraving, plastic, copper, stainless steel, and other material processing.
