Tungsten Carbide Micro Drill Bits Set - 1/8 Inch Shank - 20 Pcs

Product Description

The Micro Drill Bit for PCB, Acrylic, and Plastics features a Tungsten Carbide Tip. This drill bit is made from ultra-fine grain carbide material, ensuring a precise and easy drilling experience. It has high hardness, good toughness, wear resistance, high strength, and resistance to bending.

The Spiral Flute Bits have a sharp cutting edge that provides smooth cutting, reduces cutting force, prevents drill breakage, and improves drilling accuracy. The spiral chip space design allows for fast and clean chip removal.

These high precision drill bits feature a sharp cutting edge, milling groove, and clean surface. They offer good milling and cutting performance, working quickly and cleanly with no glitches or scrap left behind.

Key features include high work efficiency, the ability to run at higher speeds than high-speed steel, and the high hardness and good toughness provided by the high-speed steel shank.

These drill bits have a wide range of applications, suitable for drilling and engraving PCB, acrylic, plastics, fiberglass, wood, aluminum, and soft metals. They can be used on PCB drilling machines, engraving machines, CNC lathes, and machining centers, replacing the need for CNC machines and handheld tools.

Tips for using these small and fragile drill bits include ensuring vertical use and controlling CNC speed. The longer the length of the tool clamped by the chuck, the better the tool performance. If the clamping length is shorter, reducing the feed rate and cutting speed can help reduce vibration and extend tool life.

When combined with the material being processed, selecting an appropriate feed rate and cutting speed can improve tool life and achieve better processing accuracy and performance.

Specifications include cutting edge diameters ranging from 0.3mm to 1.2mm, shank diameter of 3mm / 1/8", and overall length of 38mm / 1-1/2".

These drill bits offer a long tool life with high hardness, wear resistance, strength, and resistance to bending. The spiral flute design improves cutting accuracy and chip removal, while the sharp cutting edge ensures clean and precise drilling. They are suitable for a variety of materials and can be used with various drilling equipment for high precision work.
