Drill bit for metal Tvardy HSS M2 extended 12.0 mm

Extended HSS M2 drill bit by Tvardy, 12.0 mm diameter, designed for drilling metal. This drill bit is manufactured from high-speed steel (HSS M2) to provide improved wear resistance and higher temperature tolerance compared with standard carbon-steel bits. The extended length allows deeper hole making in sheet and plate work or when using drill presses and portable machines where extra reach is required. A black-gold coating reduces friction and helps chip evacuation for more consistent drilling performance in ferrous materials.

Advantages

The HSS M2 material offers higher hardness and heat resistance during continuous drilling operations, extending tool life under load. The extended shank and flute length enable drilling of deeper holes without changing to longer tooling, while the black-gold coating improves chip flow and reduces galling on steel surfaces. The 12.0 mm cutting diameter gives a balance between rigidity and material removal rate suitable for many workshop and industrial metalworking tasks.

Suitable for

• Drilling holes in steel plates and profiles
• Through-holes and clearance holes in ferrous materials
• Workshop drilling with drill press or portable hand drills
• Industrial production runs where consistent hole quality is required

Key specifications

• Material: High-speed steel (HSS M2)
• Diameter: 12.0 mm
• Type: Extended length twist drill
• Coating: Black-gold surface treatment for reduced friction and improved chip evacuation
• Application: Designed for drilling ferrous metals and steel

How to use

Secure the workpiece firmly and select an appropriate drill speed for HSS M2 and the material thickness—use lower speeds for larger diameters and harder steels. Center-punch the drilling point to prevent walking, then start drilling with steady pressure. Use cutting fluid or appropriate coolant to reduce heat and improve hole finish, and periodically withdraw the drill to clear chips when drilling deep holes. Ensure the drill is properly clamped in the chuck and aligned to avoid undue bending or breakage.

Usage recommendations

For optimal performance, match drill speed and feed to the steel grade and thickness, apply cutting fluid during prolonged drilling, and avoid excessive side load. Inspect the cutting edges before use and replace the bit when wear or chipping affects hole quality.
