Apex 8500 Semi-Synthetic Coolant Lowers Cost and Increased Tools Life

November 2019

Cost savings is always important to any business. In addition, machining operations seek ways to improve processes and operational performance. In a particular case, Ashburn was brought in to evaluate existing processes and performance and make recommendations on improvements that would protect their production and performance while reducing cost.


A major Oilfield Services and Product manufacturer was seeking cost reduction and process improvement for a machining operation using 5/8” insert drills that are run 6 days out of the week. The customer drilled 100 pieces per day and tooling cost for one machine was calculated to be $5,200 per month. Ashburn Chemical Technologies was brought in to evaluate this process and give a recommendation.


Ashburn’s technical specialist suggested testing of APEX 8500 Semi-Synthetic Coolant in order to increase lubricity and tool life.

Test results showed that the cutting tool lasted 340% longer, and had to be replaced less often. In total, tooling costs were decreased from $5,200 to $1,508 per month.


The change to APEX 8500 Semi-Synthetic coolant ultimately saved $44,304 in annual tooling costs for this operation.
