Roll Forged HSS-drills have a high elasticity due to their production method. They have a big and robust core thickness and are the conventional tool for professional drilling under normal conditions.Fully ground HSS-Drills are made of hardened solid material. The reinforced core-section gives a better fracture-stability and enables professional drilling under narrow tolerances and longer life-time of tool. Fully ground drills should be used wherever roll-forged drills have reached their limit of performance. All fully ground drills are produced with "Split Point”. The main advantages are: Direct drilling without prior centering, safe pilot hole drilling even on round or slanting surfaces, less feeding power, increase of drilling progress, better chip removal, no jamming of the main cutting-edge. Do not overheat metal drill-bits. This can only be avoided by usage special cutting coolants (high-alloyed and heat-resistant materials) or cooling emulsion (normal steel). Brass, cast iron and most plastics can be drilled without coolants. A correct tip grind is absolutely necessary for economical drilling. We can only recommend regrinding by machine, because regrinding by hand is too imprecise and results in too early wear of tool.
Safety advice:
Always wear safety-goggles and noise-protection.
