Drill bit set EINHELL HSS-G Silver for metal, 13 pieces

The EINHELL HSS-G Silver drill bit set for metal includes 13 high-speed steel bits engineered for drilling ferrous materials. Each bit features HSS-G geometry that balances cutting performance with heat resistance, making the set suitable for repeated metalworking tasks. The bits are compatible with corded and cordless drills and cover a range of common diameters for workshop, repair and fabrication work.

Advantages

The HSS-G design provides improved wear resistance and thermal stability compared with standard carbon-steel bits, allowing higher drilling speeds and longer life in steel and similar materials. The set's variety of diameters reduces the need to change tools frequently and supports a range of metalworking operations. The solid construction and straight shanks enable reliable clamping in most drill chucks.

Suitable for

• Drilling through mild and medium steels
• Workshop fabrication and metal repairs
• Maintenance tasks on metal structures and assemblies
• Use with corded and cordless drills for general metalworking

When it may not be suitable

This HSS-G set is designed for ferrous metals and general-purpose metalworking; it is not optimized for drilling into hardened tool steels, stainless steels with high alloy content, or non-ferrous soft metals where specialized coatings or carbide tips may be preferable. For very high-speed automated machining or heavy production where carbide or coated drills are standard, these HSS-G bits may wear faster.

Key specifications

• Material: high-speed steel (HSS-G)
• Application: drilling in ferrous metals and general metalworking
• Number of pieces: 13
• Shank type: straight shank for standard chucks
• Geometry: ground twist drill geometry designed for metal cutting and heat resistance

How to use

Select the appropriate drill bit diameter for the hole required and secure it firmly in the drill chuck. Use steady feed pressure and a suitable drilling speed for HSS: moderate RPMs for larger diameters and higher RPMs for smaller diameters, while avoiding excessive speed that can overheat the bit. Apply cutting lubricant when drilling steel or thicker sections to reduce friction and improve tool life. Clear chips frequently and allow the bit to cool if it becomes hot during prolonged use.

What to consider before purchase

• Confirm the diameter range included in the set matches your project requirements.
• Check whether HSS-G is suitable for the specific metal types you will be working with.
• Ensure your drill chuck accepts straight-shank bits and secures the required diameters.

Usage recommendations

For best results when drilling metal, use cutting fluid, maintain consistent feed pressure, and choose speeds appropriate to bit diameter. Store the bits in a dry place and inspect for wear or chipping before reuse.
