## Summary description

Tvardy HSS drill bit 4.50 mm for metal, made of high-speed steel (HSS) with a black-gold surface finish. Designed for drilling clean holes in various ferrous and non-ferrous metals; suitable for hand drills and drill presses. Key attributes: 4.50 mm diameter, HSS material for heat resistance and wear performance, universal use in metalworking, maintenance and assembly tasks.

## Long description

Tvardy HSS drill bit 4.50 mm is a solid high-speed steel cutting tool designed for drilling precise holes in a wide range of metals. The 4.50 mm diameter and HSS material provide heat resistance and improved wear performance compared with standard carbon steel bits. The black-gold surface finish reduces friction and helps chip evacuation, making the bit suitable for use in both handheld drills and drill presses during assembly, maintenance, and metalworking tasks.
Advantages
The drill bit combines HSS material with a protective black-gold surface that limits heat buildup and extends service life under moderate to high cutting conditions. Its 4.50 mm diameter ensures repeatable, accurate hole sizes for fittings and fasteners. The geometry is optimized for general-purpose metal drilling, offering reliable chip removal and reduced tendency to clog when used with appropriate speeds and lubrication.
Suitable for (tasks / use cases)
Drilling holes in ferrous metals such as steel and cast iron
Drilling non-ferrous metals including aluminum, brass, and copper
Maintenance and repair work requiring precise 4.50 mm holes
Assembly tasks where consistent hole diameter for fasteners is needed
Use with hand-held drills and bench drill presses
Key specifications
Diameter: 4.50 mm
Material: high-speed steel (HSS)
Finish: black-gold surface treatment
Intended use: metal drilling (ferrous and non-ferrous)
Compatibility: suitable for hand drills and drill presses
How to use
Secure the workpiece and mark the drilling point. Select an appropriate drilling speed for the material being drilled and clamp the drill bit firmly in the chuck. For steel and other hard metals, use cutting lubricant to reduce heat and prolong bit life. Apply steady pressure and allow the drill to cut without forcing; withdraw the bit periodically to clear chips if drilling deep holes. After use, clean the bit and store it in a dry place to prevent corrosion.
Usage recommendations
Use lower speeds and cutting fluid when drilling hard ferrous metals to minimize wear. For thin sheet metals, support the workpiece to prevent deformation and use a backer to reduce burr formation. Replace the bit when wear or chipping affects hole quality.
