Drill bit DeWalt DT5052-QZ, metal, length 117 mm, 1 pc

DeWalt DT5052-QZ is a single 117 mm high-performance drill bit designed specifically for drilling metal. The bit is supplied as one piece and is intended for use with compatible portable drills and drill presses to produce accurate holes in steel and other ferrous materials. Its tapered web reduces the risk of breakage while the gold ferrous oxide coating helps prevent overheating, extending service life. Three flat sides on the shank provide secure seating in the chuck and permanent size markings above the shank give clear visibility during use.

Advantages

The DeWalt DT5052-QZ offers improved durability thanks to the tapered web design that reduces stress points and the heat-resistant gold ferrous oxide coating that slows thermal wear during prolonged drilling. Three flat sides on the shank eliminate slipping in the chuck, providing more consistent drilling accuracy. The single-piece supply is convenient for workshop inventories and professional maintenance tasks where individual replacement bits are needed.

Suitable for

• Portable drilling of steel, including alloyed and non-alloyed metals up to 900 N/mm²
• General metalworking tasks in workshops and on-site maintenance
• Precision hole drilling where controlled bit life and reduced overheating are important

Key specifications

• Material application: metal (ferrous materials, steel, alloys)
• Overall length: 117 mm
• Pack quantity: 1 piece
• Coating: gold ferrous oxide coating for improved heat resistance
• Shank: three flat sides to prevent slipping in the chuck
• Design: tapered web to reduce breakage risk
• Markings: permanent size markings located above the shank for increased visibility

How to use

Secure the DeWalt DT5052-QZ drill bit in a compatible drill chuck, ensuring the three flat sides seat firmly to prevent slipping. Select an appropriate drilling speed for the metal type—lower speeds for harder steels—and apply steady, moderate pressure. Use cutting fluid or lubricant when drilling tougher or thicker metal to reduce heat and extend bit life. Withdraw the bit periodically to clear chips and allow cooling during extended drilling operations.

Usage recommendations

For best results when drilling steel up to 900 N/mm², use a variable-speed drill, keep speeds moderate, and apply cutting fluid. Inspect the bit before use for signs of wear and replace when edges become blunt to maintain hole accuracy and prevent damage to workpieces.
