Solid Carbide Drills General Application Instructions (continued) Wrong Drilling and Chamfering Correct Drill into the solid first, then chamfer. chamfer tool [  Wrong Drilling on Inclined or Rounded Surfaces Correct When drilling on inclined or curved surfaces, use a lower feed than the standard value. The reduction of feed required is dependent on the inclination angle of the workpiece surface and the drill type (see table). reduced feed 100% feed >1° reduced feed (% of standard value) inclination 5xD 100% feed no premachine _ 3xD Long <5 x D1°100%80%premachine premachine 2° 80–50% 80–50% premachine 3° 65% 50% premachine 4° 50% premachine premachine [ 6° 30% premachine premachinePremachining is usually done with an end mill operation. Wrong Drilling on Turning Machines Hole Depths Greater than 3 x D When drilling on turning machines, the drill must be on Hole depths that are deeper than three times the centre. The tolerance range of the centre position should drill diameter may require a speed reduction. A 0,025mm not exceed ±0.025mm. On bar-turning lathes, do not drill 15% lower speed is suggested.into centre stub or bur. Cut-off tools must be mounted precisely to eliminate centre stub or bur. Do not drill into pre-existing holes. [ widia.com T145
