Solid Carbide Drills Empower Automotive Parts Manufacturing Customer Background

A well-known automotive parts manufacturer specializing in engine blocks and transmission housings faced several challenges with traditional HSS drills: short tool life, frequent tool changes, and inconsistent hole accuracy. These issues directly impacted production cycle time and product quality.

Solution
We recommended solid carbide drills with internal coolant channels, combined with an advanced AlTiN coating. The drills offered superior wear and heat resistance, while the optimized flute design effectively solved chip evacuation problems during deep-hole drilling.

Results

• Tool life increased by over 3×, significantly reducing tool change frequency

• Hole accuracy stabilized at ±0.01mm, with improved surface finish

• Per-hole machining cost reduced by ~35%

• Overall production efficiency improved by 20%, with higher line stability

Customer Feedback
“After switching to solid carbide drills, both our productivity and quality improved dramatically. Not only did we cut costs, but we also achieved more stable deliveries.” – Production Manager, Automotive Manufacturer
