How to buy original CoCud 0.3mm PCB Drill Bits in India?

Ensure you are purchasing from authorized US retailers and authorized brand partners, like CrowCrowCrow. These bits are factory-sealed and imported per-order, with all customs duties and GST included in the price. We provide an ExpressBox tracked delivery to your Indian pincode.

What materials can these 0.3mm drill bits cut through?

These CoCud micro drill bits are designed for soft materials like PCBs, acrylic, plastics, soft metals, fiberglass, and wood. Their sharp tungsten carbide edge provides clean cuts in these applications.

Can I use these 0.3mm drill bits in a regular drill chuck?

While these bits have a 1/8" shank, they are extremely fine and best used with CNC machines or specialized PCB drilling equipment that allows for precise speed control. Using them in a standard drill chuck requires careful clamping and reduced speed to prevent breakage.

What is the advantage of tungsten carbide over HSS for these bits?

Tungsten carbide offers significantly higher hardness, wear resistance, and heat resistance compared to HSS. This allows these bits to run at higher speeds for efficient drilling and maintain sharpness for longer, providing precise results in suitable materials.

How do I prevent these tiny drill bits from breaking?

Control your CNC speed carefully, as these bits are very small and easily twisted off. Ensure the longest possible chuck clamping length and reduce the feed rate and cutting speed if you notice vibration to increase tool life.

Are these drill bits suitable for hard metals like steel?

No, these 0.3mm micro drill bits are not designed for hard metals. They are optimized for softer materials such as PCBs, acrylic, plastics, soft metals, fiberglass, and wood. For steel, you would need specialized drill bits made from cobalt or titanium-coated HSS.

Key Features

PCB Drill Bits Size --- Cutting edge diameter (CED): 0.3mm / 0.012"; cutting edge length: 5.5mm / 0.217"; 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

Engineered for Precision Electronics

These CoCud micro drill bits are specifically engineered for the demands of PCB manufacturing and intricate electronics repair. Unlike general-purpose drill bits, their 0.3mm tungsten carbide tips and precise 1/8" HSS shanks are designed to create clean, accurate holes in delicate materials like circuit boards and acrylic without causing damage. The sharp cutting edge and optimized chip removal ensure a smooth drilling experience, vital for preventing tool breakage and achieving professional results in your DIY or repair projects.

Ideal for CNC & Engraving, Who Should Skip

Perfect for users with CNC machines, PCB drilling equipment, or engraving machines requiring high precision. They excel with acrylic, plastics, soft metals, fiberglass, and wood. However, these bits are extremely fine (0.3mm) and fragile; they are NOT suitable for drilling hard metals, concrete, or for use with standard drills without a suitable chuck and controlled speed. If you need bits for heavy-duty construction or general woodworking, consider larger, more robust options.

How to use

Select and Mount Bit — Choose the 0.3mm CoCud drill bit. Insert the 1/8" HSS shank into your CNC machine's collet or a compatible precision chuck, ensuring it is clamped securely for maximum stability.
Set Machine Parameters — Set your CNC machine's speed to an appropriate level for micro-drilling (consult machine manual). Use the integrated positioning ring to set the desired drilling depth accurately.
Drill with Control — Drill vertically into your material (PCB, acrylic, soft metal). Maintain a controlled feed rate and cutting speed to prevent vibration and minimize the risk of tool breakage. Ensure good chip removal.
