Drill bit for metal Smart HSS cylindrical 3 mm, 10 pcs (24-030)

Smart HSS cylindrical drill bits, 3 mm diameter, pack of 10 pieces, are designed for drilling holes in ferrous and non‑ferrous metals. Manufactured from high‑speed steel (HSS), these straight shank bits maintain hardness at elevated temperatures and offer consistent performance when used with handheld drills and drill presses. The 3 mm size provides a precise option for general metalworking, maintenance, and repair tasks in workshop and industrial environments.

Advantages

High‑speed steel construction ensures durability and heat resistance during continuous drilling operations. The cylindrical (straight) shank design fits standard chucks without requiring adapters. Supplied in a pack of ten, the set reduces downtime by providing multiple identical bits for repeat tasks or spare replacements. The small 3 mm diameter allows for accurate starter holes and fine metal fabrication work.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum, and non‑ferrous alloys
• Workshop and garage metalworking tasks
• Maintenance and repair of machinery and equipment
• Use with handheld electric drills and drill presses

Key specifications

• Material: High‑speed steel (HSS)
• Tip style: Twist drill geometry suitable for metal
• Shaft type: Cylindrical (straight) shank
• Diameter: 3 mm
• Quantity: 10 pieces

How to use

Secure the appropriate drill bit in the drill chuck and tighten firmly. Select a drill speed suitable for the metal type and bit diameter; lower speeds are generally recommended for harder metals. Use cutting fluid or lubricant to reduce heat and prolong bit life when drilling steel or stainless steel. Start drilling with steady pressure and allow the bit to do the cutting; back off periodically to clear chips for cleaner holes and reduced wear.

Usage recommendations

For best results, match drill speed and lubrication to the workpiece material: moderate speeds and cutting oil for carbon steels, lower speeds and suitable coolant for stainless steel, and higher speeds for aluminum with minimal lubricant. Inspect bits for wear or damage before use and replace when dull to maintain hole quality and prevent workpiece damage.
