Drill bit set Smart 11-KPL13 HSS for metal, 13 pieces

Smart 11-KPL13 is a 13-piece drill bit set with HSS (high-speed steel) bits designed for drilling metal. The set covers a range of commonly used diameters for general metalworking tasks and is suitable for use with hand drills and drill presses. Each bit is manufactured from high-speed steel to provide toughness and wear resistance when cutting through mild steel, sheet metal and other ferrous and non-ferrous metals.

Advantages

The HSS construction offers a balance of hardness and toughness that helps maintain sharp cutting edges and resist heat buildup during drilling. The 13-piece range provides flexibility for typical workshop repairs, fabrication and maintenance needs, reducing the need to change tools frequently. The bits are compatible with standard drill chucks and are designed for stable, accurate drilling when used at recommended speeds and with appropriate lubrication.

Suitable for

• Drilling holes in mild and medium-hard metals
• Workshop repairs and maintenance tasks
• Metal fabrication and assembly work
• Use with electric hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Number of pieces: 13
• Intended material: metal (ferrous and non-ferrous)
• Shank type: straight round shank for standard chucks
• Typical use: drilling, through-holes and starter holes in metal

How to use

Secure the chosen drill bit in the drill chuck ensuring concentric mounting and firm clamping. Mark the drilling position and, if necessary, center-punch to prevent bit wandering. Select an appropriate drill speed for the material and diameter: lower speeds for larger diameters and harder metals, higher speeds for small diameters and softer metals. Use cutting fluid or lubricant to reduce heat and improve chip evacuation when drilling metal. Apply steady, moderate pressure; avoid forcing the bit. After drilling, back the bit out periodically to clear chips and allow cooling.

Usage recommendations

For best results, use recommended drill speeds for HSS bits, apply cutting lubricant when drilling thicker or harder metals, and replace bits that show significant wear or chipping. Store the set in a dry place to prevent corrosion and organize bits by size to simplify selection during tasks.
