In modern manufacturing, standard tools often fall short when faced with complex materials and specialized machining requirements. Recently, we successfully provided a custom coolant-through flat bottom step drill to a high-end component manufacturer, helping them overcome multiple machining challenges while significantly optimizing production efficiency and product quality.
Customer Requirements Background
1、Complex Material Characteristics
- The customer primarily machined high-hardness materials such as stainless steel, titanium alloys, and hardened steel, which impose extremely high demands on tool life and machining precision.
- Built-up edges and heat accumulation during machining caused rapid tool wear, leading to low efficiency.
2、Strict Machining Requirements
- The bottom of the holes needed to be smooth and flat to meet the high precision requirements for subsequent assembly.
- Surface roughness had to be controlled within ≤Ra0.8, and hole tolerances could not exceed ±0.01mm.
3、Frequent Issues with Existing Tools
- Standard drills could not achieve zero-deviation machining, resulting in tilted or burr-filled hole bottoms.
- Traditional cooling methods were ineffective, limiting tool life to around 500 holes, and frequent tool changes increased downtime.
4、High Cost of International Brand Solutions
- A global tool manufacturer’s custom solution was priced too high, with a delivery cycle of up to 6 weeks, making it unacceptable for the customer.
Facing these challenges, the customer urgently needed an efficient, stable, and cost-effective customized drill.
Our Solution: Custom Coolant-Through Flat Bottom Drill
To meet the customer’s specific needs, we designed a coolant-through flat bottom step drill, featuring the following core advantages:
1、Coolant Channel Design
- Coolant is delivered directly to the cutting edge through internal channels, effectively reducing temperature and heat buildup.
- This design extended tool life by over 3 times, significantly lowering maintenance costs.
2、Advantages of Flat Bottom Drills
- The flat bottom design enables zero-deviation machining, producing smooth and flat hole bottoms on curved, inclined, or thin plate surfaces.
- It is particularly suitable for hard materials like stainless steel, titanium alloys, and hardened steel, ensuring stable and reliable machining quality.
3、Highly Customizable
- Based on the customer’s material properties, machine parameters, and coating requirements, we provided exclusive tool designs.
- Tool geometry angles, edge honing, and coating types can all be adjusted according to actual application needs, ensuring optimal performance.
Actual Results: Customer Feedback and Achievements
After practical testing and batch production verification, this coolant-through flat bottom step drill demonstrated outstanding performance:
- Tool Life Extension: Tool life increased from 500 holes to over 1,500 holes, reducing tool replacement frequency by 70%.
- Improved Machining Efficiency: With coolant reaching the cutting point, chip evacuation became smoother, reducing cycle times by 25%.
- Stable Machining Quality: Hole bottoms were smooth and flat, with surface roughness ≤Ra0.8 and hole tolerances controlled within ±0.01mm.
- Lower Overall Costs: Single-hole machining costs decreased by 40%, saving significant expenses for the customer.
The customer highly praised this custom drill and expressed their intention to continue collaborating with us on developing more customized tools.
