Drill bit for metal Smart 9.7 mm HSS set of 5

Drill bit for metal Smart 9.7 mm HSS set of 5 is a set of five high-speed steel (HSS) twist drill bits designed specifically for drilling through steel and a wide range of ferrous and non-ferrous metals. The 9.7 mm diameter provides a precise medium-sized hole suitable for many mechanical, workshop and repair tasks. These bits are compatible with hand-held drills and drill presses, delivering stable performance when used at recommended speeds and with appropriate cooling or lubrication for extended life.

Advantages

The HSS construction offers enhanced heat resistance and wear durability compared with standard carbon steel, reducing edge softening at high drilling speeds. A ground twist geometry ensures consistent chip removal and straight drilling, while the pack of five provides spares for repeated operations or multiple projects. The balanced manufacturing tolerances support reliable runout control in both hand drills and bench-mounted machines.

Suitable for

• Drilling holes in mild and medium-strength steel
• Working with stainless steel, aluminium and other non-ferrous metals
• General workshop maintenance and repair tasks
• Use with hand drills and drill presses for metal fabrication

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 9.7 mm
• Quantity: 5 pieces per pack
• Tip type: standard 118° twist point (suitable for general metal drilling)
• Compatibility: suitable for use in hand-held drills and drill presses

How to use

Secure the workpiece and mark the drilling position before starting. Select an appropriate drilling speed for the metal type—slower speeds for harder steels and higher speeds for softer metals such as aluminium. Use cutting fluid or lubricant to reduce heat buildup and improve chip evacuation. Apply steady, moderate pressure and avoid forcing the bit; periodically withdraw the bit to clear chips. After drilling, remove burrs and inspect the bit for wear; replace when edge rounding or excessive runout occurs.

Usage recommendations

For best results, pre-drill pilot holes when making large-diameter holes, use a center punch to prevent wandering, and keep cutting speeds and feed rates appropriate to the workpiece material. Store bits dry and clean to prevent corrosion and maintain performance over time.
