This 4mm HSS-G drill bit is suitable for metal, wood, and plastic projects, making it a versatile choice for DIY and professional work alike.

Key features include: high-quality HSS-G steel for wear resistance; precision-ground cutting edge for clean holes; 4mm diameter ideal for small pilot holes; optimized flute design for efficient chip removal and heat control; corrosion-resistant coating for extended life; designed for high-speed drilling; compact, easy-to-store packet.

This bit is engineered for high-speed drilling. Use the recommended speeds and feed rates for the material you’re drilling, starting at a light feed and increasing as needed. For metal, use lighter pressure and allow cooling as needed; for wood and plastic, you can often run a bit quicker while still listening for signs of strain or overheating.

Yes. This drill bit uses a standard 1/4-inch shank, which fits most power drills and drill drivers that accept standard twist drill bits.

Steps: secure and clamp the workpiece, mark the hole, start at a slow speed to establish a pilot, then gradually increase speed while applying steady, moderate feed. Use proper lubrication or cutting fluid for metal, and back out the bit occasionally to clear chips. Maintain a straight drilling angle to prevent bit binding.

Keep the bit in its original pack or a dedicated purpose-made bit case, clean any debris after use, dry thoroughly to prevent rust, and store in a cool, dry place. The corrosion-resistant coating helps, but proper storage and occasional cleaning extend life.

Yes, it’s designed for high-speed drilling and general-purpose use across metal, wood, and plastic. Always wear eye protection, clamp your workpiece, and avoid overheating by using appropriate speeds and intermittent feeding.

Wear appropriate PPE (eye protection, gloves as needed), secure the workpiece, use clamps, maintain proper speed and feed, avoid overheating, and keep the work area clean and free of distractions. The bit’s coating provides corrosion resistance, but never force the bit or drill through hardened materials.
