What materials can these 0.2mm micro drill bits drill through?

These 0.2mm micro drill bits are designed for precision work on PCBs, acrylic, plastics, aluminium, soft metals, fiberglass, and wood. Their Tungsten Carbide cutting edge ensures smooth drilling and accuracy on these materials.

Can I use these 1/8" shank drill bits in a regular drill chuck?

Yes, these 1/8" (3.175mm) shank drill bits can be used in standard three-jaw keyless or keyed drill chucks by clamping the hex flats. However, they are optimized for CNC machines and engraving equipment for best results.

How do I prevent these tiny drill bits from breaking?

Control your CNC speed carefully and ensure the chuck clamps the bit securely. For shorter clamping lengths, reduce the feed rate and cutting speed to minimize vibration and increase tool life. These micro bits are delicate and require precise handling.

Are these drill bits suitable for hard metals like steel?

While these bits can drill soft metals like aluminium, they are primarily designed for PCBs, plastics, and wood. For harder metals or general steel drilling, consider high-speed steel (HSS) or cobalt drill bits with larger diameters and appropriate coatings.

What is the difference between Tungsten Carbide and HSS for drill bits?

Tungsten Carbide offers superior hardness, wear resistance, and heat resistance, making it ideal for precision work and higher speeds on materials like PCBs and plastics. High Speed Steel (HSS) is generally tougher and more flexible, often used for the shank or for drilling softer metals.

What is the benefit of the positioning ring on these drill bits?

The positioning ring on these drill bits helps reduce machine set-up time by providing a consistent reference point for depth control, thereby increasing overall efficiency during precision drilling operations.

About this item

CoCud 0.2mm micro PCB drill bits provide precision for intricate work in India. This 20-piece set features a 0.2mm cutting edge diameter and a 3.175mm (1/8") HSS shank, with a durable Tungsten Carbide cutting edge. Suitable for CNC machines, engraving, and drilling PCBs, acrylic, plastics, soft metals, fiberglass, and wood. Imported directly, all customs and GST are included in the price. Delivery via ExpressBox tracked service within 25-36 days.

The Tungsten Carbide material ensures high hardness, toughness, and wear resistance, allowing for precise drilling and efficient material removal with low heat. The sharp cutting edge prevents tool breakage and ensures accuracy. These bits are designed for high work efficiency, with a large chip removal space for smooth operation. The integrated positioning ring helps reduce machine set-up time.

For optimal performance and tool life, control your CNC speed and ensure the chuck clamps the bit securely. Due to their micro size, these bits are delicate; reduce feed rate and cutting speed to minimize vibration if clamping length is short. These precision tools are ideal for electronics hobbyists and professionals in India seeking reliable components.

Key Features

PCB Drill Bits Size --- Cutting edge diameter (CED): 0.2mm / 0.008"; cutting edge length: 3.5mm / 0.138"; shank diameter: 3.175mm / 1/8"; overall length: 38mm / 1-1/2".
Wide Applications --- Widely used for drilling PCB (print circuit board), acrylic, plastics, aluminium, soft metal, fiberglass, wood, etc. Suitable for PCB drilling machines, engraving machines, CNC and high precision special drilling equipment.
Sharp Cutting Edge --- Sharp cutting edge provides smooth drilling, low cutting force and drilling accuracy to prevent tool breakage. Large chip removal space, smooth chip removal, and low drilling heat.
Tungsten Carbide --- Tungsten carbide tip has high hardness, good toughness, wear resistance, high strength, resistance to bending and heat resistance, providing a precise and easy experience.
Useful Tips --- The mini drill bit is too tiny and easily twisted off. Be careful and control your CNC speed. The longer the chuck clamps, the better. The positioning ring reduces machine set-up time and increase efficiency.

Why choose this product

Precision for Intricate Electronics Work

CoCud micro PCB drill bits are engineered for the demanding precision required in electronics manufacturing and hobbyist projects. The 0.2mm cutting edge and Tungsten Carbide construction allow for clean, accurate holes on circuit boards and delicate materials. Unlike generic drill bits, these are designed for high-speed CNC and engraving machines, ensuring minimal material tear-out and preventing breakage. Imported directly, these bits offer a reliable alternative for Indian makers needing exact specifications for their projects.

Ideal for PCB Work, Who Should Consider Alternatives

These bits are perfect for drilling PCBs, acrylic, plastics, soft metals, fiberglass, and wood. They excel in CNC and engraving applications where precision is paramount. However, due to their micro size and delicate nature, they are not suitable for heavy-duty drilling or very hard materials like hardened steel. If you require bits for general construction or large-diameter holes, consider a different type of drill bit. Always control CNC speed and ensure proper chuck clamping to prevent damage.

How to use

Select and Mount Bit — Choose the appropriate 0.2mm bit from the set. Securely insert the 1/8" (3.175mm) HSS shank into your CNC machine's collet or a compatible drill chuck, ensuring it is clamped firmly.
Set CNC Speed and Depth — Program your CNC machine or set your drill speed. For these micro bits, use high speeds but control the feed rate carefully to prevent vibration and breakage. Set the drilling depth accurately.
Drill with Precision — Initiate the drilling process, allowing the sharp Tungsten Carbide edge to cut smoothly. Ensure good chip removal and low drilling heat. Monitor the process for any signs of excessive vibration.
Clean and Store — After use, carefully remove the bit and clean off any debris. Store the bits in their protective boxes to prevent damage and maintain their sharpness for future precision tasks.
