Drill bit AWTools M2 HSS-TiN 5 mm Split Point Xtreme (Black Line)

AWTools M2 HSS-TiN 5 mm Split Point Xtreme (Black Line) is a precision metal drill bit engineered for reliable performance in metalworking. Constructed from M2 high-speed steel with a titanium nitride (TiN) coating, this 5 mm drill provides enhanced surface hardness and improved wear resistance. The Split Point Xtreme tip geometry reduces drilling walk and improves initial centering, enabling cleaner and more accurate holes in workshop and industrial environments.

Advantages

The M2 high-speed steel core offers a balance of toughness and heat resistance suitable for repeated metal drilling. The TiN coating increases surface hardness, reduces friction, and helps extend tool life under normal cutting conditions. The Split Point Xtreme design minimises lateral slip at contact, improving hole positioning without requiring a pilot hole in many cases. The standard 5 mm diameter makes this bit compatible with common chucks and holders used in benchtop and hand drills.

Suitable for

• Drilling mild and medium-hard steels
• Working with non-ferrous metals such as aluminium and brass
• General workshop and maintenance tasks
• Production runs requiring repeatable hole quality

When it may not be suitable

This drill bit is not intended for drilling extremely hard materials such as hardened tool steels or carbide. For high-volume production under heavy loads or where coolant/peck drilling cycles are impractical, a carbide or coated specialist bit may be more appropriate. Also, the TiN coating improves wear resistance but can be worn away under excessive heat or improper use.

Key specifications

• Material: M2 high-speed steel (HSS)
• Coating: Titanium nitride (TiN)
• Tip type: Split Point Xtreme
• Diameter: 5 mm
• Typical applications: Metal drilling, workshop and industrial use

How to use

Secure the bit firmly in the drill chuck and set the drill to an appropriate speed for the material being drilled—lower speeds for harder steels, higher speeds for softer metals like aluminium. Use steady feed pressure and allow the bit to cut without forcing; excessive force increases heat and accelerates wear. Where possible, apply cutting fluid or coolant to reduce temperature and prolong tool life. Withdraw the bit occasionally to clear chips when drilling deeper holes.

What to consider before purchase

• Match drill diameter (5 mm) to the required hole size and fastener specifications.
• Ensure your drill or machine can provide suitable speed and torque for metal drilling.
• Consider if TiN coating and Split Point tip meet your wear and centring needs compared with uncoated or carbide options.
• Confirm compatibility with available chucks or drill holders.

Usage recommendations

For best results, select cutting speeds appropriate to the workpiece material, use light coolant or cutting oil for ferrous metals, and avoid excessive feed pressure. Regularly inspect the cutting edges for wear and replace the bit when accuracy degrades.
