Drill bit Smart HSS for metal 8.5 mm — set of 5

The Smart HSS drill bit set for metal, 8.5 mm, contains five identical high-speed steel bits designed for drilling ferrous and non-ferrous metals. Each 8.5 mm bit is intended for use with handheld drills and drill presses and is manufactured to maintain cutting performance in workshop repairs, maintenance tasks and general metalworking. The set provides a compact set of replacement bits for situations where repeated or multiple identical holes are required.

Advantages

High-speed steel composition ensures good hardness and heat resistance during metal cutting operations. The uniform 8.5 mm diameter across all five bits simplifies inventory and replacement when multiple identical holes are needed. Compatibility with standard drill chucks allows use with both cordless and corded handheld drills as well as drill presses. The set format reduces downtime by providing spare bits for repeated tasks.

Suitable for

• Drilling holes in ferrous metals such as steel and iron
• Drilling in non-ferrous metals such as aluminum, brass and copper
• Workshop repairs and maintenance where multiple identical holes are required
• DIY metalworking projects and amateur metal fabrication
• Use with handheld drills and drill presses for consistent hole diameter

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 8.5 mm
• Quantity in set: 5 identical drill bits
• Shank type: round shank compatible with standard chucks
• Intended use: cutting/drilling in ferrous and non-ferrous metals

How to use

Secure the chosen 8.5 mm HSS drill bit in the drill chuck and tighten firmly before operation. Clamp the workpiece or secure it in a vise to prevent movement. Mark the drilling position and, when appropriate, use a center punch to guide the bit and reduce walking. Start drilling at low speed to establish the hole, then increase speed as cutting continues while applying steady, moderate pressure and periodic withdrawal to clear chips. Use appropriate cutting fluid or lubricant when drilling tougher steels to reduce heat and extend bit life. After use, clean and store the bits in a dry place to prevent corrosion.

Usage recommendations

For best results with the Smart HSS 8.5 mm drill bits, match drill speed and feed to the workpiece material: lower speeds and cutting fluid for hardened or thick steels, higher speeds for soft non-ferrous metals. Replace bits that show excessive wear, chipping, or loss of cutting performance to maintain hole quality and operator safety.
