Description

• Metal drill bits HSS Ground - DIN 338.
• The THUNDERWEB design is characterised by a conical shaped web which gets thicker towards the back of the drill bit. The web is the internal core of the drill bit
• Parabolic web cross sectionLarge web thickness. Strength built inAccepts higher feed pressure and torqueLess breakages. Good for drilling deep holes and on curved surfacesLong life
• Flute GeometryTHUNDERWEB flute form ejects hot chips rapidly. Dissepates heat better increasing lifetimeOpen flute form reduces drill drawback when drilling deeper holesSharpened edges reduce binding for faster cleaner cutsFlatter twist angle creates smaller chippings, ideal for drilling harder steels ie: stainless steel
• 135° Split PointPrecision starting, drill won't walkPenetrates quicklyGood for drilling on curved surfacesRequires less effort / feed pressureExcellent for very hard materials
