The KWB 513904 wood twist drill bit is a precision-engineered tool designed for accurate drilling in various wood types. With a diameter of 4 mm and a total length of 50 mm, this drill bit is manufactured from high-quality CrV steel, ensuring durability and consistent performance. It features a 1/4" hexagon shank compatible with ISO 1173 E 6.3 standards, making it suitable for use with cordless drivers, drills, and standard bit holders. The bit is chemically blackened and features ground spirals, a center point, and two cutting wings to ensure clean, break-out free holes.

Advantages

This drill bit offers exceptional precision due to its specialized center point and dual cutting wings, which prevent wandering and ensure clean entry and exit points in the material. The use of high-quality CrV steel provides excellent wear resistance, while the ground spirals facilitate efficient chip removal during the drilling process. Its standardized 1/4" hexagon shank allows for rapid tool changes, making it highly versatile for users who frequently switch between different drilling and driving tasks.

Suitable for

• Drilling precise holes in softwoods
• Drilling precise holes in hardwoods
• Use with cordless screwdrivers and drills
• Projects requiring quick bit changes via 1/4" hex holders

When it may not be suitable

This drill bit is specifically designed for wood applications and is not suitable for drilling into metal, masonry, or concrete. Using this tool on hard materials will cause rapid dulling of the cutting edges and potential damage to the bit.

Key specifications

• Diameter: 4 mm
• Total length: 50 mm
• Material: CrV steel
• Shank type: 1/4" hexagon (ISO 1173, E 6.3)
• Design: Center point with 2 cutting wings

How to use

Insert the 1/4" hexagon shank of the drill bit into your cordless driver or bit holder until it is securely locked in place. Position the center point of the drill bit exactly where you intend to create the hole. Apply steady, moderate pressure while maintaining a perpendicular angle to the wood surface. Start the drill at a controlled speed to ensure the cutting wings engage properly with the wood fibers, allowing the ground spirals to clear the debris as you progress through the material.

What to consider before purchase

• Verify that your drill or driver accepts 1/4" hexagon shanks
• Ensure the 4 mm diameter meets the requirements of your specific project
• Confirm the material being drilled is wood, as this bit is not intended for metal or stone

Usage recommendations

For the best results and to extend the lifespan of the drill bit, maintain a consistent drilling speed and avoid applying excessive lateral force, which could cause the bit to bend or snap.
