SA220 Hand-held Pneumatic Drill Bit Grinder

(1) Button Bit Grinding Machine/ Button Bit Grinder

You’ve probably known for a long time that regular grinding is essential for productivity. But what you may not know is just how important it is. We decided to crunch some numbers and find out. By wearing down your button bits by a third you’ll slow down your penetration rate by 30%. But more importantly you’ll increase your running costs by at least 40%! And why? Because the hole will take longer to drill and your labor and rig running costs will escalate. And at the end of the day you’ll have drilled fewer holes.

Staying sharp makes a lot of business sense!!!

Maintaining penetration can save you money. Firstly, you need good grinding equipment for a start – and you won’t find any better than ours. And secondly, you need to spend time and energy grinding your bits. But the rewards are significant. For an investment amounting to just 2% of your overall drilling costs, you can restore your worn bits to their former glory. And with these bits you cut the time and manpower needed to drill the hole. In fact, you can reduce overall drilling costs up to 30%. How?
