Drill bit AWTools HSS M2 15.0 mm — solid metal twist drill, single piece

AWTools HSS M2 15.0 mm solid metal twist drill is a single-piece high-speed steel drilling tool designed for general metalworking and maintenance tasks. With a 15.0 mm cutting diameter and M2 HSS material, this drill bit is suited for drilling steel, cast iron, non-ferrous metals and other hard materials where elevated hardness and heat resistance are required. The solid single-piece construction supports use in handheld drills and machine spindles where a robust, dependable cutting performance is needed.

Advantages

The M2 high-speed steel composition provides good hardness and edge retention at elevated temperatures, reducing wear during continuous drilling. Solid one-piece construction minimises vibration and runout compared with inserted-tip designs, delivering straighter holes and consistent cutting. The 15.0 mm diameter offers a standard size for through-holes and clearance drilling in metal fabrication and maintenance tasks. The bit is compatible with common drill chucks and machine holders for flexible use in both portable and stationary equipment.

Suitable for

• Drilling holes in mild and alloy steels
• Through-holes and clearance holes in metal fabrication
• Maintenance and repair work using handheld or bench drills
• Drilling cast iron, aluminium and other non-ferrous metals

Key specifications

• Material: High-speed steel (M2)
• Cutting diameter: 15.0 mm
• Type: Solid twist drill, single piece
• Intended use: Metal drilling and general machining
• Compatibility: Suitable for handheld drills and machine spindles with compatible chucks

How to use

Select the correct drill speed and feed for the material being drilled; lower speeds are generally recommended for harder metals. Secure the workpiece to prevent movement and ensure the drill is held perpendicular to the surface for accurate hole placement. For best results, use appropriate cutting fluid or coolant to reduce heat and extend tool life, and clear chips frequently to avoid clogging the flutes. Inspect the bit before use for damage and replace when excessive wear or chipping is observed.

Usage recommendations

For drilling steel and harder alloys, start at a moderate speed and apply steady pressure. Use cutting oil when drilling ferrous materials and increase pecking or chip clearing on deep holes to prevent bit overheating. Store the drill bit in a dry place and avoid impacts to preserve the cutting edge.
