## Summary description

Tvardy HSS black‑gold metal drill bit, 18.00 mm diameter. High‑speed steel (HSS) construction with black‑gold surface coating for improved wear resistance and smoother chip evacuation. Designed for drilling holes in steel and common ferrous/non‑ferrous metals; suitable for hand drills and drill presses. Supplied as single pieces or in pack quantities (1/25/50) for workshop or industrial use.

## Long description

Tvardy HSS black-gold metal drill bit, 18.00 mm diameter, is a twist drill designed for drilling holes in steel and a range of common ferrous and non‑ferrous metals. The bit is made from high‑speed steel (HSS) and features a black‑gold surface coating that improves wear resistance and supports smoother chip evacuation. Its solid carbide‑compatible shank is intended for use in standard chucks of hand drills and drill presses, offering stable engagement and straightforward installation.
Advantages
The HSS construction combined with a black‑gold coating increases cutting edge durability and heat resistance compared with uncoated HSS bits. The coating reduces friction during drilling, which helps prolong tool life and promotes more consistent hole quality. The 18.00 mm diameter is suitable for medium‑sized holes, and the shank profile is compatible with common tool holders, enabling use in both portable and stationary drilling equipment.
Suitable for
 Drilling through mild and medium steel
 Working with common ferrous and non‑ferrous metals (e.g., iron alloys, aluminum, brass)
 Use in hand drills and drill presses with appropriate chuck capacity
 Workshop maintenance, fabrication, and light industrial production where single or multiple quantity supply is required
When it may not be suitable
This drill bit is not intended for use in hardened steels above typical HSS capabilities or for heavy interrupted cutting conditions that require carbide tooling. It may wear faster if used continuously at high spindle speeds without proper cooling or lubrication. For glass, masonry, ceramic tiles, or concrete, a specialized masonry or carbide tip drill should be used instead.
Key specifications
 Material: High‑speed steel (HSS)
 Surface finish: Black‑gold coating for reduced friction and improved wear resistance
 Diameter: 18.00 mm
 Shank type: Solid shank compatible with carbide‑rated chucks (standard round shank)
 Intended materials: Steel and common ferrous/non‑ferrous metals
 Supply options: Single piece or packs (1 / 25 / 50)
How to use
Select a drill press or hand drill with a chuck that accepts an 18.00 mm shank and secure the workpiece to prevent movement. Mark the drilling point and, if necessary, use a center punch to avoid bit walking. Start at a low speed to establish the hole, then increase speed as appropriate for the metal being drilled while applying steady feed pressure. Use cutting fluid or appropriate lubrication when drilling steel to reduce heat and improve chip flow. Withdraw the bit periodically to clear chips on deep holes and to allow cooling.
What to consider before purchase
 Confirm your drill chuck capacity supports an 18.00 mm shank
 Ensure HSS tooling is suitable for the hardness of the material you will drill
 Decide between single‑piece or pack quantities based on consumption and inventory needs
 Plan for appropriate cutting lubricant and cooling for extended tool life
Usage recommendations
For best results when drilling steel, use moderate spindle speed, steady feed, and a suitable cutting fluid. For repeated or production drilling, consider regular inspection of the cutting edges and replace the bit once wear affects hole diameter accuracy or surface finish.
