If you want precision drilling in a wide range of material including wood, steel, aluminium and more, this 17 piece drill bit set from Clarke is ideal. Manufactured to the highest quality, all 17 bits in the set are Titanium coated for durability and high performance. The bits operate at cooler temperatures than standard HSS bits which means they can be used for prolonged periods without risk of damage. The Titanium coating also extends the lifespan of the bits, meaning they won't need to be replaced as quickly or as often as traditional HSS bits, saving you money and effort. Complete with bits of various sizes to suit a large range of applications.
