Stainless Steel Straight Shank Drill Bits for Metal, Iron and Aluminium, 1mm to 10mm Diameters

Professional and DIY users alike need drill bits that can handle tough materials without dulling or breaking. These stainless steel straight shank twist drill bits are purpose-built for drilling into metal, iron, and aluminium workpieces with accuracy and reliability. With a straight shank design that fits securely in standard hand electric drill chucks, each bit offers straightforward tool changes and stable drilling performance. Available in a full range of sizes from 1.0mm up to 10.0mm, including half-millimetre increments, you can select the exact diameter needed for your specific task, whether that's fine pilot holes or larger fixings. The stainless steel construction provides good resistance to corrosion, making these bits suitable for repeated use in workshop environments.

Features and Construction

Each drill bit is built for practical metal drilling applications. The straight shank profile ensures compatibility with most electric drills, while the stainless steel material offers a balance of strength and corrosion resistance.

Material and Build

Manufactured from stainless steel, these bits are designed to resist rust and maintain cutting performance over time. The twisted flute geometry helps evacuate chips during drilling, keeping the cutting edge clear for smoother progress through metal, iron, and aluminium.

Size and Practical Fit

Available individually per diameter, you can choose from 22 size options: 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.2mm, 3.5mm, 4.0mm, 4.2mm, 4.5mm, 5.0mm, 5.2mm, 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, and 10.0mm. This range covers most standard fastener and hole requirements for general metalworking.

Uses and Placement

These bits are suited for both professional tradespeople and home workshop users who need to drill clean holes in metalwork projects.

Metal Fabrication and Repair Work

Use these bits for drilling into steel sheet, aluminium profiles, iron brackets, and other common workshop metals. The straight shank holds securely in a drill chuck for repetitive tasks like fixing hinges, installing brackets, or creating clearance holes for bolts.

DIY Home Projects

For home enthusiasts, these bits work well for drilling into metal furniture, aluminium window frames, or iron gates. The range of sizes means you can tackle small electronic enclosures as well as larger structural jobs.

Benefits and Buying Value

Buying individual sizes allows you to get exactly the bits you need without paying for sets you won't use.

Reuse and Low Maintenance

Stainless steel construction offers good corrosion resistance, so bits stay functional longer when stored in a dry workshop. Resharpen the cutting edges as needed to extend useful life.

Why Choose This Product

Instead of buying a mixed set with sizes you rarely use, you can order the precise diameter each project demands. This approach saves money and reduces clutter, while the stainless steel build provides reliable cutting performance on metal, iron, and aluminium workpieces.
