CoCud Micro PCB Drill Bits 3.175mm Shank 0.8mm Cutting Edge Tungsten Carbide Printed Circuit Board Drill Bits for CNC Drilling Engraving Machine 10pcs

Attributes:

* Cutting edge diameter (CED): 0.8 mm * Cutting edge length: 10 mm * Shank diameter: 3.175 mm * Overall length: 38 mm * Cutting edge material: Tungsten carbide * Shank material: HSS (High Speed Steel)

Package Includes:

* 10pcs x PCB Drill Bits

Application Features:

--- Widely used for drilling PCB (Printed Circuit Board), acrylic, plastic, aluminum, soft metal, fiberglass, wood, etc. Suitable for PCB drilling machine, engraving machine, CNC, high precision special drilling equipment. Use vertically and control CNC speed well. Work quickly and cleanly, no glitches or scraps left behind. --- Tungsten carbide bits have high hardness, good toughness, wear resistance, high strength, bending resistance and heat resistance, giving you a precise and easy experience. Carbide materials have better milling and engraving performance, so they can run faster than high-speed steel and have higher work efficiency. Sharp cutting edge ensures smooth drilling, low cutting resistance, drilling accuracy, and prevents tool breakage. Large chip evacuation space, smooth chip evacuation, low processing heat. Locating ring reduces machine setup time and improves efficiency.

Useful tips:

--- The mini drill bit is too small and easily twisted. Be careful and control the CNC speed. The longer the chuck clamp, the better. If the clamping length is short, the feed rate and cutting speed should be reduced to reduce vibration and extend tool life.
