## Long description

Tvardy HSS 6.80 mm black-gold drill bit for metal is a high-speed steel cutting tool designed for drilling metal workpieces. With a 6.80 mm diameter and a black-gold surface treatment, this drill bit offers improved wear resistance and reduced friction when cutting into steel and non-ferrous metals. It is suitable for use in both handheld drills and drill presses in workshop and light production environments, providing consistent hole quality for assembly, repair and fabrication tasks.
Advantages
The black-gold coating increases surface hardness and decreases chip adhesion, which helps extend tool life and maintain cutting performance over multiple drilling cycles. The HSS material retains strength at elevated temperatures and provides reliable durability when drilling a variety of metal alloys. Precise manufacturing tolerances ensure a true diameter and stable concentricity for accurate hole sizing and minimal runout.
Suitable for
 Drilling holes in mild and alloy steels
 Working with non-ferrous metals such as aluminum and brass
 Handheld drilling and machine drilling (drill press, bench drill)
 Maintenance, assembly and metal fabrication tasks
Key specifications
 Material: high-speed steel (HSS)
 Diameter: 6.80 mm
 Coating: black-gold surface treatment for reduced friction and increased wear resistance
 Shank type: straight shank suitable for standard drill chucks
 Intended use: metal drilling (ferrous and non-ferrous)
How to use
Secure the workpiece and select an appropriate cutting speed for the material being drilled. Install the drill bit firmly in the chuck, ensuring proper alignment and minimal runout. Begin drilling with steady pressure, allowing the bit to cut without excessive force. For thicker or harder metals, use intermittent pecking motions to clear chips and reduce heat buildup. Apply suitable cutting fluid when drilling steels to prolong tool life and improve surface finish.
Usage recommendations
For best results, match spindle speed and feed rate to the workpiece material, keep the bit cool using cutting fluid when drilling ferrous metals, and inspect the tip condition regularly; replace the bit when wear or chipping affects hole accuracy.
