Drill bit set Smart HSS for metal 11.0 mm — 5 pcs

Set of five Smart HSS drill bits for metal with a nominal diameter of 11.0 mm. These drill bits are made from high-speed steel (HSS), offering hardness and wear resistance suitable for drilling through ferrous and non-ferrous metals. The set is intended for use in hand drills and drill presses and is suitable for workshop maintenance, fabrication, and tasks that require precise 11.0 mm holes.

Advantages

High-speed steel construction ensures a balance of hardness and toughness for drilling metal. The consistent 11.0 mm diameter across all five pieces provides repeatable hole size and reduces the need for frequent tool changes. The HSS material maintains cutting edge integrity under typical drilling speeds and provides resistance to wear when used with appropriate lubricants. The set format supplies multiple bits for replacement or simultaneous staging in professional and hobby workflows.

Suitable for

• Drilling precise 11.0 mm holes in steel, iron, aluminum and other metals
• Use with electric hand drills and drill presses
• Workshop maintenance, metal fabrication and repair tasks
• Repeated drilling where multiple identical bits reduce downtime

Key specifications

• Material: high-speed steel (HSS)
• Nominal diameter: 11.0 mm
• Quantity in set: 5 pieces
• Intended materials: ferrous and non-ferrous metals
• Compatible tools: hand drills and drill presses

How to use

Mark the drilling position and secure the workpiece in a vise or clamp to prevent movement. Select an appropriate drill speed for the metal being worked: lower speeds for harder steels, higher speeds for softer metals like aluminum. Use cutting fluid or lubricant to reduce heat and extend bit life, and apply steady, moderate pressure while drilling. Withdraw the bit periodically to remove chips and prevent clogging. Replace bits from the set as needed when wear or loss of sharpness occurs.

Usage recommendations

For best performance and longevity, use cutting oil when drilling steel, maintain correct drill speeds and feed pressure, and allow the bit to cool between prolonged drilling operations. Store the bits in a dry place to avoid corrosion.
