Drill bit set AWTools AW42317, 13 pcs, titanium-coated metal bits, sizes 2–8.0 mm

AWTools AW42317 is a 13-piece drill bit set designed for metalworking tasks. The set contains high-speed steel bits with a titanium coating in sizes from 2.0 mm to 8.0 mm, supplied in a compact storage case. Bits are intended for use with standard drill chucks and are suitable for drilling steel and other ferrous and non-ferrous metals within the covered diameter range.

Advantages

The titanium coating increases surface hardness and provides improved wear resistance compared with uncoated bits, extending usable life under typical workshop and maintenance conditions. High-speed steel substrate offers a balance of toughness and cutting performance for general metal drilling. The coordinated size range from 2.0 mm to 8.0 mm allows selection of appropriate diameters for pilot holes, through-holes and medium-size holes without changing to specialty bits. The compact case keeps bits organized and protects cutting edges during storage and transport.

Suitable for

• Drilling holes in steel, aluminium and other ferrous and non-ferrous metals
• Workshop repair and maintenance tasks
• Light construction and installation work requiring small to medium hole diameters
• DIY projects where standard drill chucks are used

Key specifications

• Material: high-speed steel (HSS) with titanium coating
• Number of pieces: 13
• Diameter range: 2.0 mm to 8.0 mm
• Intended use: metal drilling (ferrous and non-ferrous)
• Compatibility: standard drill chucks
• Storage: compact protective case

How to use

Select the correct diameter for the hole required and fit the bit securely in the drill chuck. Use appropriate drill speed and feed for the material: lower speeds and steady pressure for harder steels, higher speeds for softer non-ferrous metals. Apply cutting fluid or lubricant when drilling steel to reduce heat and prolong bit life. Retract the bit periodically to clear chips and avoid overheating. After use, clean the bits and return them to the protective case to maintain cutting edges.

Usage recommendations

For best results when drilling hardened or stainless steels, use reduced speed and suitable coolant; for aluminium and soft alloys, moderate speed and light feed give cleaner holes. Replace bits that show significant wear or chipping to maintain hole quality and drilling efficiency.
