Drill bit set Smart HSS for metal 1.2 mm — 10 pcs

Set of 10 Smart HSS drill bits for metal, 1.2 mm diameter, designed for creating precise small holes in steel, iron, non‑ferrous metals and thin sheet materials. The bits are made from high‑speed steel (HSS) to provide wear resistance and consistent cutting performance in general metalworking tasks. This compact set is suitable for use with handheld drills and drill presses for repair, assembly and hobby applications that require accurate small‑diameter holes.

Advantages

The HSS material offers good hardness and heat resistance for typical metal drilling operations, helping maintain cutting edge life during intermittent or continuous use. A 1.2 mm diameter is optimal for precision holes, pilot hole drilling and delicate assembly work where tight tolerances are required. The kit of 10 identical bits ensures replacements are available on demand, reducing downtime when bits wear or break. The shank size and standard twist geometry make these bits compatible with most common chucks on handheld drills and bench drills.

Suitable for

• Drilling small-diameter holes in steel and iron
• Pilot holes for screws and fasteners in metalwork
• Work with non-ferrous metals such as aluminum and brass
• Repair, maintenance and hobby projects requiring precise small holes
• Use with handheld drills and drill presses for controlled drilling

Key specifications

• Material: High‑speed steel (HSS)
• Diameter: 1.2 mm
• Quantity: 10 pieces
• Tip type: Twist point for metal drilling
• Compatible with: Standard drill chucks on handheld drills and drill presses

How to use

Secure the workpiece firmly and mark the drilling point before starting. Fit a 1.2 mm HSS bit into the drill chuck and tighten securely. For best results when drilling metal, use a moderate spindle speed and steady pressure; reduce speed for harder steels and increase for softer non‑ferrous metals. Apply cutting fluid or light oil to the drill bit and workpiece to aid cooling and lubrication for cleaner holes and longer tool life. Withdraw the bit periodically to clear chips and avoid clogging.

Usage recommendations

Wear appropriate eye protection and gloves when drilling. For thicker or hardened steels, pre‑drill with a larger pilot if needed and use controlled speed with intermittent coolant to prevent overheating. Replace bits that show excessive wear or chipping to maintain hole quality.
