Choose The Best Drill Point Geometry Modern Machine

13/01/2004  Drill point standards are accepted based on inflexible precedent rather than logical deduction and experimentation. The 118-degree point, when the full length of the cutting for example, is erroneously assumed to be a good compromise or general-purpose point for drilling a variety of different metals. Varying the point angles has nothing to do with cutting action. A compromise between high- and low-lip clearance angles, not the non-cutting point

Helical Micro-Drill Point Design and Grinding Journal of ...

A new drill point geometry, termed the helical drill point, specifically intended for micro-drills, is developed in order to alleviate the disadvantages of existing planar micro-drill points. A mathematical model for this new drill point has been established. It is shown that this model is more general than existing drill point models. The commonly used conical, cylindrical and planar drill point models are only special cases of the helical model. For uniquely determining the grinding ...

DRILL POINT GEOMETRY , an article by JOSEPH MAZOFF

Four faceted drill points consist of separate cutting lip (primary) and secondary heel clearance (relief) facets (fig. E) and extending the secondary facets to G the midway point of the chisel produces the apex (point) (fig. F) at the center of the chisel's long axis. As a result, it produces a self-centering point, eliminating center punching and pilot holes. It won't walk, and is the most accurate of all points. It's

The Art of GRINDING A DRILL - da7c.co.uk

A little practice on these lines will be found immensely helpful in getting the hang of drill grinding. Golden rules to remember are:(1) Keep the drill cool by frequent dipping in soluble oil or soapy water. It should be always wet, as this also helps the grinding. (2) Use a smooth-grit wheel with a true surface, running at high speed. (3) Take time and do not rush the job. Once a drill has overheated through dry grinding

Drill-point grinding machines - Cleveland Lineartechnik

Precise drill point grinding is ensured by the minimum distance between drill bushing (contact point) and grinding wheel. The result is an optimum uniform cutting geometry for the production of clean holes under favorable cutting conditions. Additional benefit: easy setting even for smallest diameters – thanks to high-quality adjustment optics.
