Make the most of your storage with BUNKER - choose from modular options, 4 clever ready-made combinations or stylish roller cabinets.Drill bit colour : polished Suitable for drilling in alloyed and unalloyed steel up to a tensile strength of 900 N/mm2, cast steel, cast iron, sintered iron, temperate iron, non-ferrous metals and hard plastics. Flatter twist angle creates smaller chippings, ideal for drilling harder steels ie: stainless steel. The THUNDERWEB design is characterised by a conical shaped web which gets thicker towards the back of the drill bit. They also feature a self-centering split point tip, which means that you do not need to pre-punch or pilot drill up to 10mm in diameter. As a standard drill can spin upwards of around 500 - 700rpm, the friction can cause a substantial build-up of heat.

This generally means the length of the entire drill bit itself is significantly longer for diameter it has. Precise response when positioning the bit due to its split point and 135° point angle as well as excellent dimensional accuracy also characterize this drill bit.
