Dormer, 61 mm Overall 2

Bore into hard surfaces with ease thanks to this drill bit from Dormer. It's made from wear-resistant high-speed steel, which means it's durable enough to pierce through materials like aluminium alloys. The 118° point angle gives you the advantage of stability, especially when you're using a hand-operated drilling machine. Its working part has a 3mm diameter, so it fits the bill for creating holes for small fasteners.

• Titanium nitride coating improves resistance to corrosion, assuring you of long-lasting service

• Mechanical workshops

You can sharpen this unit using a simple grinding machine. For safety, it's important to wear gloves and goggles while sharpening the bit.
