Drill bit Smart HSS for metal 1.7 mm — set of 10

Drill bit Smart HSS for metal 1.7 mm — set of 10 are high-speed steel drill bits intended for drilling small-diameter holes in metal. Each bit has a straight shank and a 1.7 mm cutting diameter, supplied as a set of ten pieces suited to hand drills and drill presses. The bits are designed for common workshop tasks, maintenance and light manufacturing where accurate, repeatable small holes in mild steel, non-ferrous metals and similar materials are required.

Advantages

These HSS drill bits provide hardness and heat resistance typical of high-speed steel, enabling reliable cutting performance when drilling metals at moderate speeds. The straight shank ensures compatibility with standard chucks, while the small 1.7 mm diameter is useful for precision work and pilot holes. Supplied as a set of ten, the package supports multiple uses or replacement without immediate reordering, making them practical for routine workshop and maintenance projects.

Suitable for

• Drilling small holes in mild steel and low-alloy steels
• Working with non-ferrous metals such as aluminum, brass and copper
• Creating pilot holes for screws and small fasteners
• Light manufacturing, maintenance and hobby metalworking

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 1.7 mm
• Shank type: straight shank
• Package quantity: 10 pieces
• Intended use: drilling in metal and similar materials

How to use

Secure the selected drill bit in the chuck of a hand drill or drill press, ensuring the bit is centered and firmly tightened. Clamp the workpiece to prevent movement. Select an appropriate drilling speed for 1.7 mm HSS bits and the metal being drilled—lower speeds for harder materials, higher speeds for softer non-ferrous metals—and apply steady pressure without forcing the bit. Use cutting fluid or lubricant when drilling steel to reduce heat and prolong bit life. Withdraw the bit periodically to clear chips and allow cooling during longer holes.

Usage recommendations

For best results, use cutting oil when drilling steels, start holes with a punch or center drill for precise positioning, and replace worn bits to maintain hole quality; store the set in a dry place to avoid corrosion.
