A success story from a customer in the food industry who optimized their production process using the Nine9 ACE Spot Drill.

The Challenge:

The customer was drilling holes in 316L stainless steel using a carbide drill (135° angle), followed by a chamfering process. Previously, this required a secondary operation to remove burrs and clean up the surface — adding both time and cost.

The solution: By adopting ACE Spot Drill into both ends of the process —

for spotting before drilling and 90° chamfering after drilling

✅ Spotting Before Drilling:

The ACE Spot Drill ensures precise hole positioning and produces burr-free surface.

✅ Chamfering After Drilling:

With its 90° angle and optimized geometry, the client use same tool to make 90° chamfering. ACE spot drill not only eliminating the need for secondary surface cleanup, the long tool life of the insert adds further value by reducing tool change frequency.

Thanks to these improvements, the customer is now applying the same solution to other components — boosting both productivity and quality.
