Grinding Instructions The regrinding of the tungsten carbide button bits, or rather the reprofiling of the buttons should be made when the wear of the tungsten carbide button is maximum half the button diameter. |
Periodic Bit Reconditioning |
|
|||||||||||||||||||||||||||||
| Periodic bit reconditioning will prolong a button bit's ability to produce the greatest total metereage at the fastest penetration rate.Reconditioning involves reprofiling the tungsten carbide buttons and restoring the gauge relief taper using Diaroc / Scandia or Super Diaroc Tools and removing the body steel to give the button the correct protrusion using Boroscan Tools. | ||||||||||||||||||||||||||||||
| General Points | ||||||||||||||||||||||||||||||
The Diaroc / Scandia and Super Diaroc diamond tools with their built-in arc profile are in the grinding process performing a reprofiling of the worn button back to the original factory profile. |

| Restore the Profile of the Button | |
| When reprofiling the buttons with the Diaroc / Scandia and Super Diaroc Tools move the grinding machine in circular movements. | |
 For each size of the tungsten carbide button
bit a corresponding diamond tool is to be applied in the grinding-reprofiling process.The grinding-reprofiling with the Diaroc / Scandia and Super Diaroc should always be done with water flushing. Adjust the water valve for proper water feed. Correct feed is when the drips are joining up in a small stream. Proper Grinding Machine The method of reprofiling is quickly and efficiently carried out using the new VS-200 or VS-260 Hand-Held Air Grinders in conjunction with Diaroc / Scandia and Boroscan tools at a working speed under load of approximately 20,000 rpm. It is essential that this tool is always used with adequate supply of oil in the air supply. |
