Drill Bit Set DeWalt DT1182-QZ 13 Pieces HSS high-speed steel for metal drilling

DeWalt DT1182-QZ 13 Pieces HSS high-speed steel drill bit set is designed for cutting into ferrous and non-ferrous metals. The set contains a range of sizes made from high-speed steel (HSS) to deliver durability and improved heat resistance during continuous drilling. Intended for workshop and professional environments, the kit supports general metal fabrication, maintenance and repair operations where consistent hole quality and tool life are required.

Advantages

The HSS construction provides a balance of toughness and hardness suitable for metalworking, while heat resistance helps maintain cutting performance under higher temperatures. A variety of sizes in one set allows quick selection for different hole diameters without changing tool families. The bits are compatible with standard drill chucks and are suitable for handheld and bench-mounted drilling equipment, ensuring versatile use in many workshop situations.

Suitable for

• Drilling holes in steel and iron sheets and plates
• Working with non-ferrous metals such as aluminum and copper
• General fabrication and metal maintenance tasks
• Workshop and professional on-site repair jobs

Key specifications

• Material: High-speed steel (HSS)
• Number of pieces: 13
• Intended application: Metal drilling (ferrous and non-ferrous)
• Compatibility: Standard three-jaw drill chucks; suitable for hand drills and drill presses
• Design characteristics: Twist drill geometry for general-purpose metal cutting

How to use

Select the appropriate drill bit size for the required hole diameter and secure it in the drill chuck. When drilling metal, clamp the workpiece securely and use a center punch to mark the start position if precision is needed. Start at a low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply steady pressure and use cutting lubricant for improved life and cooler cutting when drilling harder metals. Clear chips frequently and back the bit out periodically on deep holes to remove swarf.

Usage recommendations

For best results, match drill speed and feed to the metal type and bit size; use slower speeds and cutting fluid for harder steels, and moderate speeds for aluminum. Store bits in a protective case after use to prevent edge damage and corrosion. Inspect bits for wear or chipping before use and replace when dull to maintain hole quality and reduce risk of breakage.
