Are Coolant Feeding Drills The Answer To Drilling Efficiency?

The answer is - it depends.  When production drilling is routine and you have consistent volume of work it’s a good idea to evaluate the use of coolant feeding, solid carbide drills. Time is money. 

The machine tool to be used is the first and most critical component, if you have a machine with coolant through spindles and pumping capacity for both high volume and high pressure, the biggest obstacle has been overcome.  That’s not to say you shouldn’t consider purchasing a machine tool featuring these capabilities when drilling costs are significant.

  • ​Material to be drilled
  • Accuracy and finish
  • Estimated number of holes over time

Of the three factors listed above,  the most important  one that goes into selecting a drill is the estimated number of holes over a period of time.  All of these will significantly aid in the decision making concerning the purchase and use of coolant feeding drills. 

Productivity Analysis: Switch to a Regal Drill and Save

By recently comparing a manufacturer’s current drill to a Regal drill  that uses high production drilling techniques

productivity analysis

usingadvanced machine tools and the recommended coolant feeding coated carbide drills, we saw a savings of over $2400. Overall,  the number of holes per drill, speed, and number of holes per hour were much greater with Regal’s Drill but the real savings is in machine utilization. Regal’s drill needed only 8 hours to perform the same work as the existing drill did in 50 hours, significantly reducing the machine time cost. Along with this, only 3 tools were needed annually for Regal’s drill compared to 20.
