Drill Bit for Metal Smart HSS cylindrical 1.9 mm set of 10 (model 11-019)

The Smart cylindrical HSS drill bit set contains ten 1.9 mm diameter high-speed steel bits designed for drilling metal and metal alloys. These solid, straight-shank bits are aimed at producing small-diameter holes with consistent geometry and cutting precision. Construction in HSS material offers improved wear resistance and heat tolerance compared with standard carbon-steel drills, making the set suitable for light to medium metalworking operations in workshops and maintenance environments.

Advantages

The HSS composition ensures sustained cutting performance and dimensional stability when drilling steel, non-ferrous metals and thin sheet materials. A cylindrical (straight) shank provides compatibility with standard drill chucks and easy replacement in hand drills and drill presses. The set format of ten identical bits supplies spare tools for repetitive tasks and reduces downtime from tool changes.

Suitable for

• Drilling small holes in mild and alloy steels
• Working with non-ferrous metals such as aluminium and brass
• Maintenance and repair tasks requiring precise, repeatable holes
• Thin sheet metal applications and light fabrication
• Use in hand drills and bench drill presses with standard chucks

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 1.9 mm
• Shank type: cylindrical / straight
• Quantity in set: 10 pieces
• Intended material: ferrous and non-ferrous metals, thin sheets

How to use

Select an appropriate drilling speed and feed rate for the workpiece material; lower speeds are recommended for harder steels and higher speeds for soft non-ferrous metals. Secure the workpiece with clamps or a vise to prevent movement, and centre-punch the drilling point to reduce walking. Use cutting fluid or lubricant when drilling steel to reduce heat buildup and prolong bit life. Begin drilling with light pressure, increase steadily as the bit engages, and clear chips frequently to maintain cutting efficiency.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Inspect the drill bits before use and replace any worn or chipped bits to maintain hole quality. Store the set in a dry place to prevent corrosion and keep bits organized for quick access.
