Method of manufacturing a printed circuit board drill |
| abstract |
An abrasive tipped drill of .006 to .125 inch diameter is provided for drilling holes in printed circuit boards. A composite sintered abrasive tip of cemented carbide and diamond or cubic boron nitride is formed such that the carbide can be ground away to expose the abrasive as the cutting surfaces of the drill. A shank of tough material having high transverse rupture strength is provided with a reduced section which forms the body of the drill. The tip is secured to the reduced section and flutes are ground overthe combined length ofthe tip and reduced section. |
