What is the primary difference between standard twist drill bits and brad point wood drill bits?

Brad point drill bits feature a sharp center spur and outer cutting spurs designed specifically for clean wood penetration. The center spur prevents bit wandering upon startup, while the outer spurs shear wood fibers cleanly along the perimeter, preventing tear-out and producing smooth entry and exit holes compared to standard general-purpose twist bits.

Can these wood drill bits be used in standard corded and cordless drills sold in India?

Yes, these bits are universally compatible with standard 10mm (3/8-inch) and 13mm (1/2-inch) keyless or keyed chucks commonly found on rotary drills and drill drivers in India. Sets with 1/4-inch hex shanks can also be inserted directly into quick-connect impact drivers and hex-drive screwdrivers.

How to buy original uxcell Tungsten Carbide PCB Drill Bits in India?

Purchase from authorized US retailers and authorized brand partners, like CrowCrowCrow, to ensure you receive factory-sealed, genuine products. All customs duties and GST are included in the price, and items are shipped via ExpressBox tracked delivery to your Indian pincode.

What materials can these uxcell PCB drill bits cut?

These bits are great for PC Boards, plastics, fiberglass, wood, and soft metals. Their precision makes them ideal for detailed work on circuit boards and fine woodworking projects, but they are too tiny and fragile for heavy-duty construction materials.

Are these drill bits fragile?

Yes, these drill bits are very tiny and fragile. They require careful handling and controlled CNC speed to prevent breakage. They are designed for precision work on softer materials, not for heavy-duty drilling or impact applications.

What is the shank size of these uxcell drill bits?

The shank diameter for these uxcell PCB drill bits is 3mm, which is approximately 1/8 inch. This standard size is compatible with most PCB drilling machines, engraving machines, CNC equipment, and high-precision hand tools.

How long will these Tungsten Carbide drill bits last?

Made from high-hardness Tungsten Carbide with high wear resistance, these bits offer a long tool life for precise applications. Their spiral flute design also helps reduce cutting force and prevent breakage, improving drilling accuracy and efficiency.

Why choose this product

Precision Engineering for Intricate Work

These uxcell Tungsten Carbide PCB drill bits are engineered for micro-precision tasks. Unlike generic bits, their sharp spiral flutes and high-hardness material ensure clean entry and exit holes on delicate circuit boards and fine woodworking projects. They reduce cutting force, minimizing the risk of material damage or bit breakage, crucial for detailed electronic assembly and model making. Imported for Indian makers who demand accuracy and reliability in their tools.

Ideal for Electronics & Fine Woodworking

Perfect for PCB drilling, CNC engraving, and working with plastics, fiberglass, and soft metals. If you need to drill precise holes for components, hinges, or intricate joinery, these bits excel. However, they are extremely small and fragile; users requiring larger diameter bits for heavy-duty construction or those who prefer robust, less delicate tools might find them unsuitable. For general construction drilling, consider larger, more robust bit sets.

How to use

Select and Mount Bit — Carefully select the 0.4mm Tungsten Carbide bit from its protective case. Insert the 3mm (1/8") shank into the chuck of your PCB drill, CNC machine, or high-precision hand tool. Ensure it is securely tightened to prevent slippage.
Set Machine Parameters — For CNC or automated machines, set appropriate RPMs and feed rates. Given the bit's fragility, use lower speeds and controlled feed rates to avoid breakage. Consult your machine's manual for recommended settings for micro-drilling.
Drill with Precision — Begin drilling at the designated points. Apply steady, light pressure. The spiral flute design will help clear chips effectively. Avoid excessive force, as these bits are designed for precision, not heavy material removal.
Clean and Store — After use, carefully remove the bit and clean any debris. Store the bits back in their protective case to prevent damage and loss, ensuring they remain ready for your next precision project.
