## Long description

Tvardy HSS metal drill bit with a 4.20 mm cutting diameter and a black-and-gold surface finish designed for drilling steel and other metals. Made from high-speed steel (HSS), the bit combines hardness and heat resistance to maintain cutting performance under typical workshop and construction conditions. The 4.20 mm diameter provides a precise hole size for fastening, mounting, and component preparation tasks.
Advantages
The HSS material offers elevated hardness and thermal stability compared with standard carbon steel bits, supporting sustained drilling into ferrous and non-ferrous metals. The black-and-gold finish improves surface durability and can aid in chip evacuation and reduced friction during cutting. The 4.20 mm size delivers consistent hole dimensions and is compatible with common fastening operations and pre-drilling requirements.
Suitable for
 Drilling holes in steel and other metals
 Workshop fabrication and metalworking
 Maintenance and repair tasks requiring precise metal holes
 Construction and assembly where small-diameter metal holes are needed
Key specifications
 Cutting diameter: 4.20 mm
 Material: High-speed steel (HSS)
 Surface finish: Black-and-gold coating
 Intended use: Metal drilling (ferrous and non-ferrous)
 Typical applications: Workshop, maintenance, construction
How to use
Secure the workpiece and select an appropriate drill chuck and speed for the metal type and thickness. Use cutting fluid or lubricant when drilling steel to reduce heat buildup and extend tool life. Start with a centered pilot or center punch if precise hole placement is required, then advance the bit steadily with moderate pressure. Retract occasionally to clear chips and maintain cooling. After drilling, inspect the hole for burrs and deburr as necessary.
Usage recommendations
For best results, match drill speed to the metal being drilled: use lower speeds for harder steels and higher speeds for softer metals. Apply cutting fluid when drilling stainless steel or thicker sections to reduce wear. Replace the bit when signs of dulling or excessive vibration appear to ensure hole accuracy and operator safety.
