## Long description

Tvardy HSS drill bit for metal with a 7.80 mm cutting diameter and black‑gold finish is designed for drilling steel and other ferrous materials. Made of high‑speed steel, this bit provides consistent cutting performance and improved resistance to wear during repeated drilling operations. The bit is suitable for use in handheld drills and drill presses for metal fabrication, maintenance, and repair tasks where precise hole diameter and durability are required.
Advantages
The high‑speed steel (HSS) composition ensures good heat resistance and retained hardness at drilling speeds typical for metalworking. The black‑gold surface finish reduces friction and provides additional protection against corrosion and wear, extending the service life of the drill bit. A 7.80 mm cutting diameter offers a consistent, standard hole size for fittings and fasteners commonly used in metal assemblies. The bit’s geometry is optimized for stable drilling in ferrous materials, helping to reduce burr formation and improve hole accuracy.
Suitable for
 Drilling holes in steel sheets, plates and profiles
 Metal fabrication and assembly work
 Maintenance and repair of machinery and equipment
 Use in handheld drills and drill presses for metalworking
Key specifications
 Material: high‑speed steel (HSS)
 Cutting diameter: 7.80 mm
 Surface finish: black‑gold coating for reduced friction and corrosion resistance
 Intended material: steel and other ferrous metals
 Compatible tool types: handheld electric drills and drill presses
How to use
Secure the workpiece and mark the drilling point. Mount the drill bit in the chuck and tighten securely. Select an appropriate cutting speed and feed for the thickness and hardness of the metal being drilled; start at a moderate speed and adjust as needed. Apply steady pressure, keeping the drill perpendicular to the work surface. Use cutting fluid or lubrication when drilling thicker or harder steels to reduce heat and improve chip evacuation. After drilling, clear chips from the hole and inspect for burrs or irregularities.
Usage recommendations
For best results, use with appropriate cutting fluid and clamp the workpiece to prevent movement. Match drill speed to material hardness: lower speeds for harder steels and higher speeds for softer ferrous alloys. Replace the bit when cutting edges show significant wear or chipping to maintain hole quality and safety.
