Drill bit set Smart SM-11-KPL19 — 19 pieces HSS for metal

Drill bit set Smart SM-11-KPL19 — 19 pieces HSS for metal contains nineteen high-speed steel (HSS) twist drills sized to cover common metalworking diameters. The set is intended for drilling steel and other ferrous materials and is compatible with both hand drills and drill presses. Bits are ground with a standard point angle suitable for general-purpose metal drilling, providing consistent penetration and good wear resistance for routine workshop and maintenance tasks.

Advantages

The kit provides a broad range of sizes in a single compact set, reducing the need to purchase individual bits for common repair and fabrication jobs. High-speed steel construction offers a balance of hardness and toughness for sustained cutting performance in steel and similar metals. The uniform twist geometry and precise tip grind help maintain concentricity and reduce walking when starting holes, improving accuracy and reducing rework.

Suitable for

• Drilling steel, cast iron and other ferrous materials
• Routine workshop maintenance and repair
• Metal fabrication, fitting and assembly tasks
• Use with hand-held electric drills and bench drill presses

Key specifications

• Material: High-speed steel (HSS)
• Number of pieces: 19
• Drill type: Twist drill with standard point geometry
• Intended material: Steel and other ferrous metals
• Compatibility: Hand drills and drill presses

How to use

Select the appropriate drill diameter for the hole required and secure the workpiece in a vice or fixture to prevent movement. Fit the drill bit into the chuck and tighten securely. Use cutting fluid or oil when drilling ferrous metals to reduce heat and prolong bit life. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply steady, moderate pressure and withdraw occasionally to clear chips.

Usage recommendations

For best results, match drill speed and feed to the diameter and material: lower speeds for larger diameters and harder steels. Use appropriate personal protective equipment such as safety glasses and gloves. Inspect bits for wear or damage before use and replace worn bits to maintain hole quality and operator safety.
