Drill Bit AWTools M2 HSS-TiN 10 mm Split Point Xtreme (Black Line)

AWTools Drill Bit M2 HSS-TiN 10 mm Split Point Xtreme (Black Line) is a solid high-speed steel twist drill designed for accurate metal drilling. The M2 HSS substrate provides strength and heat resistance for demanding drilling tasks, while the titanium nitride (TiN) coating increases surface hardness and extends tool life. The Split Point geometry reduces walking on the workpiece, enabling quicker centring and cleaner hole starts when used in hand drills or drill presses.

Advantages

The TiN coating enhances wear resistance and reduces friction, which helps maintain cutting performance over a longer service life. Split Point tip geometry minimises wandering and decreases the need for centre-punching on many metal surfaces. Made from M2 high-speed steel, the drill bit offers improved toughness and heat tolerance compared with carbon-steel bits, making it better suited for repeated metal drilling operations.

Suitable for

• Drilling through mild and medium steels
• General metalworking and maintenance tasks
• Use in hand-held drills and bench or floor drill presses
• Workshop and industrial production environments

When it may not be suitable

This 10 mm M2 HSS-TiN bit is designed for drilling metals and is not optimised for masonry, concrete, ceramic tiles or glass; using it on such materials will result in poor performance and possible tool damage. For very hard alloys or hardened steels, carbide or cobalt-specific drills may be more appropriate to maintain acceptable tool life and cutting speed.

Key specifications

• Material: M2 high-speed steel (HSS)
• Coating: Titanium Nitride (TiN)
• Diameter: 10 mm
• Tip geometry: Split Point for reduced walking
• Flute: Standard spiral flute for chip evacuation
• Suitable toolholders: 3-jaw chucks and keyed/quick-change drill chucks

How to use

Secure the drill bit in the chuck ensuring correct alignment and adequate clamping. Select a drilling speed appropriate for the metal type and drill diameter—moderate RPMs for larger diameters and harder materials—and apply steady feed pressure without excessive force. Use cutting fluid or lubricant to reduce heat and improve chip evacuation when drilling steels and alloys. For accurate starts, especially on smooth or curved surfaces, a centre punch or light pilot dimple can be used even though the Split Point reduces walking.

What to consider before purchase

• Confirm that a 10 mm diameter suits the hole size required for your application.
• Ensure compatibility with your drill chuck and the intended drilling speeds.
• Evaluate whether TiN-coated HSS is appropriate for the specific metal or alloy you plan to machine.
• Consider if a carbide or cobalt drill is needed for very hard or abrasive materials.

Usage recommendations

Use cutting fluid for improved life and hole quality, start at lower speed when drilling harder steels, and inspect the tip for wear—regrind or replace when chipping or excessive dulling is observed to maintain accuracy and safety.
