DEWALT DT5923-QZ 19-Piece HSS-G DIN 338 Metal Drill Bit Set

The DeWalt DT5923-QZ 19-Piece HSS-G DIN 338 Metal Drill Bit Set is intended for accurate hole drilling in metal. Each bit is manufactured from high-speed steel and uses a ground construction. The set is rated for drilling alloyed and unalloyed steel. Its composition supports workshop, maintenance, fabrication and general metalworking tasks. Individual bits provide a practical selection for common metric hole sizes.

Precision-ground surfaces are designed to improve concentricity, maintain consistent cutting performance and assist chip removal. The jobber-length format suits general-purpose drilling where standard-length bits are required. These bits can be used with portable drills and stationary drilling machines. Diameters run from 1 mm to 10 mm in 0.5 mm increments. This graduated range allows closely spaced diameter selection without large gaps between sizes.

• DIN 338 compliance provides a defined dimensional standard for the drill bits.
• 900 N/mm² maximum tensile strength rating applies when drilling suitable steels.
• Cast steel, cast iron and sintered iron are included among the specified materials.
• Nickel, brass and bronze are also listed as suitable drilling materials.
• Drill chuck mounting allows the bits to be secured in an appropriate chuck.
