Drill Bit Set Forsage HSS for Metal 4.0 mm (10 pcs) in Plastic Case

Forsage HSS drill bit set for metal includes ten 4.0 mm high-speed steel bits supplied in a compact plastic case. The set is designed to provide standardized cutting performance for drilling through various metals and metal-compatible materials, offering a uniform 4.0 mm diameter across all bits. The plastic case organizes the bits for convenient transport and storage, protecting cutting edges from damage and helping maintain tool readiness for workshop, maintenance, and light industrial tasks.

Advantages

High-speed steel composition ensures wear resistance and heat tolerance during continuous drilling operations in metal. Having ten identical 4.0 mm bits reduces downtime for regrinding or measurement checks and provides immediate replacements when a bit becomes worn. The included plastic storage case secures bits in individual slots to prevent contact and edge dulling while making it simple to keep the set together and transportable.

Suitable for

• Drilling holes in mild and medium-hard metals
• Workshop and general maintenance tasks
• Creating pilot holes for fasteners and rivets
• Light industrial and fabrication work
• Hobbyist metalworking and repair jobs

Key specifications

• Bit material: High-speed steel (HSS)
• Nominal diameter: 4.0 mm
• Quantity: 10 pieces
• Shank type: straight cylindrical shank compatible with standard drill chucks
• Storage: plastic case with individual slots for bits
• Typical use: metal drilling and metal-compatible materials

How to use

Secure the appropriate drill from the case into a drill or drill press chuck, ensuring the shank is properly seated and tightened. Select recommended drill speed and cutting conditions for the target metal, apply cutting lubricant when drilling harder metals, and start drilling with steady feed pressure to avoid chatter. After use, clean chips from the flutes and return bits to the case to protect cutting edges and maintain organization.

Usage recommendations

Use cutting fluid or lubricant when drilling stainless steel or other hard alloys, reduce speed for harder materials, and inspect bits periodically for wear. Store the set in a dry place to prevent corrosion and handle bits by the shank to keep cutting edges sharp.
