Drill Bit Set DeWALT DT5911-QZ 10 pcs HSS-R 162 mm Metal

The DeWALT DT5911-QZ 10 pcs HSS-R 162 mm Metal drill bit set contains ten high-speed steel bits designed specifically for drilling metal. Each bit is 162 mm long and manufactured from rolled HSS-R to provide consistent cutting geometry and adequate resistance to wear during repetitive metalworking tasks. The set is compact and lightweight, intended to supply reliable drilling performance for workshop and on-site use.

Advantages

Rolled HSS-R construction offers a balance of toughness and hardness for efficient metal cutting while maintaining affordability. The 162 mm length gives extra reach for thicker workpieces or clamped assemblies. A set of ten bits ensures a range of commonly used diameters is available in one kit, reducing the need to change tools frequently during a job. The bits are suitable for use with standard drills and provide predictable chip removal and hole quality when used with appropriate speed and feed rates.

Suitable for

• Drilling through mild steel, alloy steel and non-hardened metals
• Workshop fabrication and maintenance tasks
• Automotive repair and metal fabrication
• General DIY and construction tasks involving metal components

Key specifications

• Material: Rolled high-speed steel (HSS-R)
• Quantity: 10 pieces
• Length: 162 mm per bit
• Intended use: Metal drilling
• Weight (set): 236 g

How to use

Select a drill bit diameter appropriate for the hole required and secure the workpiece to prevent movement. Fit the bit into the drill chuck and tighten securely. Use moderate drilling speed and steady feed when penetrating metal; higher speeds may be appropriate for smaller diameters while larger diameters typically require lower speeds. Apply cutting fluid or lubricant to reduce heat buildup and improve chip evacuation. After drilling, retract the drill while it is still rotating to clear chips from the hole.

Usage recommendations

For best results, use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed to the metal type and bit diameter, and use cutting fluid when drilling to extend tool life and maintain hole quality. Store the bits in a dry place to avoid corrosion and inspect bits for wear before use; replace any bit with significant dulling or damage to maintain consistent performance.
