DeWalt DT5127-QZ HSS Metal Drill Bit 3.5 mm

The DeWalt DT5127-QZ HSS metal drill bit is a precision-engineered tool designed for high-performance drilling in various metal surfaces. With a diameter of 3.5 mm and a total length of 75 mm, this drill bit is manufactured from high-speed steel to ensure durability and consistent results. Its robust construction and ground-from-solid design provide excellent concentricity, making it a reliable choice for both professional metalworking tasks and demanding DIY projects.

Advantages

This drill bit features a specialized black oxide finish that significantly enhances its resistance to corrosion, ensuring a longer service life even under frequent use. The precision-ground 118-degree point angle allows for rapid and accurate penetration into materials, reducing the risk of walking on the surface. Its type N flute geometry is optimized for efficient chip removal, which helps maintain drilling speed and prevents overheating during operation.

Suitable for

• Drilling in steel and alloyed materials
• Working with non-alloyed metals
• Applications in cast iron and sintered iron
• Drilling in brass and nickel
• Portable and stationary drilling setups

This drill bit is not intended for drilling into hardened steel, masonry, concrete, or wood, as these materials require specialized bits with different geometries and material compositions. Using this bit on materials exceeding its hardness rating may lead to premature dulling or breakage.

Key specifications

• Diameter: 3.5 mm
• Total length: 75 mm
• Material: High-speed steel (HSS)
• Point angle: 118 degrees
• Finish: Black oxide
• Cutting direction: Right-hand

To use the drill bit, ensure it is securely fastened in a compatible drill chuck. Mark the center of the hole to be drilled to ensure accuracy. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is recommended to use a cutting fluid when working with metal to reduce friction and heat, which helps preserve the sharpness of the cutting edge.

What to consider before purchase

• Verify the required hole diameter for your specific application
• Ensure your drill chuck is compatible with a 3.5 mm shank
• Check the hardness of the target material to ensure it is within the recommended range

For optimal performance and longevity, always allow the drill bit to cool down periodically during extended drilling sessions and avoid applying excessive lateral force, which can cause the bit to snap.
