These twist drills for metalworking are made of HSS steel and comply with DIN 338. The 135° drill bit tip with cross-grinding in accordance with DIN 1412 C enables precise spot drilling without centre punching. The THUNDERWEB spiral shape ensures rapid chip evacuation and therefore less heat generation and therefore a longer tool life. Compared to a roll-rolled twist drill, these drills can achieve up to 40 % faster drilling progress and up to 50 % lower feed force. THUNDERWEB drills are suitable for machining alloyed and unalloyed steel with a strength of up to 900 N/mm².

These twist drills for metalworking are made from extremely heat-resistant, cobalt-alloyed HSS steel and comply with DIN 338. The surface of the drill bits is polished. The 135° drill bit tip with cross-grinding enables precise spot drilling without centre punching. The four cutting edges ensure rapid chip evacuation and therefore less heat generation and therefore a longer service life. The drill bits are suitable for machining high-alloy steel and metal with a strength of up to 1000 N/mm², such as acid and heat-resistant steel and stainless steel. The drill core has a conical design and becomes stronger towards the shank. This strengthens the drill bit and increases the service life of the spiral. From a nominal diameter of 5 millimetres, these drill bits have a 3-face clamping shank for a better hold in the drill chuck.
