Drill bit DeWalt DT5152-QZ, for metal, 93 mm length, pack of 10

DeWalt DT5152-QZ drill bit for metal is a precision-ground twist drill designed for reliable performance in metalworking. With an overall length of 93 mm and supplied as a pack of 10, this right-hand cutting drill bit features a type N flute and a 118° point angle for fast penetration and accurate hole making. The black oxide finish improves corrosion resistance and the solid-ground construction ensures consistent concentricity and long tool life when used in compatible steels, cast iron, sintered iron and non-ferrous metals.

Advantages

The DeWalt DT5152-QZ offers rapid drilling through a variety of metals thanks to its precision 118° point and ground geometry. Its black oxide surface treatment increases resistance to corrosion and reduces friction during cutting, contributing to longer service life. Ground from solid stock, the bit maintains excellent concentricity for accurate, repeatable holes and is suitable for use in standard drill chucks on both portable and stationary drilling equipment.

Suitable for

• Drilling holes in steel and alloyed steels up to 900 N/mm²
• Work on cast iron and sintered iron components
• Fabrication and repair tasks involving nickel, brass and other non-ferrous metals
• Portable hand drills and bench or column drilling machines with standard chucks

Key specifications

• Overall length: 93 mm
• Pack quantity: 10 pieces
• Point angle: 118°
• Flute type: Type N (right-hand cutting)
• Finish: Black oxide
• Material suitability: Steel, alloyed and non-alloyed metals, cast iron, sintered iron, nickel, brass
• Manufacture: Precision ground from solid stock for improved concentricity

How to use

Mount the drill bit securely in a compatible standard drill chuck and ensure the workpiece is fixed to prevent movement. Select an appropriate cutting speed and feed for the material being drilled; harder materials require lower speeds and steady feed. Use cutting fluid or lubricant when drilling alloyed steels, cast iron or other harder metals to reduce heat and extend bit life. Withdraw periodically to clear swarf and avoid clogging the flutes.

Usage recommendations

For best results, choose cutting speeds and lubricants tailored to the specific metal: low speeds and suitable cutting oil for high-strength steels, and moderate speeds for non-ferrous metals. Inspect bits regularly for wear or chipping and replace the bit when accuracy or cutting performance degrades. Store in a dry place to preserve the black oxide finish.
