Tool Life Champions

The SDP solid carbide drill stands out due to its exceptionally long tool life and durability. This is achieved through several innovative design features:

Sumi-Power Coating: This specialized coating provides excellent wear resistance and increased adhesion resistance, leading to an extended drill life.

Optimized Cutting Edge: The curved cutting edge and optimized cutting-edge geometry reduce cutting forces, minimizing stress on the drill and thus extending its lifespan.

New Land Design: This feature ensures very high drilling accuracy over an extended period.

Balanced Material Properties: The SDP drill offers a good balance between toughness and wear resistance, resulting in stable, long tool life.

Elliptical Flute Form: This design improves chip formation and enables excellent chip evacuation, which reduces wear and extends the drill's lifespan.

In comparative tests, the SDP drill demonstrated impressive performance:
- In a tool life comparison, the SDP drill achieved three times the tool life compared to competitor products.
- In a fracture toughness test, the SDP drill was able to achieve a cutting length of approximately 60 meters, while the competitor product failed after approximately 20 meters.

These features make the SDP solid carbide drill an extremely durable and reliable tool, enabling high productivity and cost-efficiency in industrial manufacturing.

Extended Tool Life Achieved Through Unique Design
Introducing the SDPX SumiDrill Power Series: This new series features an innovative design that delivers impressively long tool life and uninterrupted performance.

Key features that contribute to its enhanced durability include:

Advanced Coating Technology
The SDPX series utilizes a state-of-the-art HF coating for superior thermal wear resistance.

This coating consists of:
- A TiAlCrSi-based super-multilayer coating with excellent wear and heat resistance.
- A tough TiAlB-based layer that enhances coating hardness and fracture resistance.

This combination provides an optimal balance between wear and fracture resistance, significantly extending tool life.

Innovative Cutting Edge Design
The new cutting edge design of the SDPX series reduces stress concentration and prevents chipping, even during high-performance drilling with heavy cutting loads. This is a major contributor to extended tool life.

RP Design for Reduced Cutting Forces
The unique RP design of the SDPX series ensures extremely low cutting forces, enabling:
- Highly efficient drilling
- Reduced tool burden
- Extended tool life

Improved Chip Evacuation
The wide flute of the SDPX drills allows for smooth chip evacuation, preventing chip jamming and reducing wear, which further extends tool life.

Performance Comparison
In tests, the SDPX series demonstrated impressive results:
-When machining carbon steel (C50), it achieved 2.8 times the drilling efficiency and 1.3 times the tool life compared to conventional drills.
-After drilling 111 meters, the SDPX series showed significantly less wear than conventional drills after only 67 meters.

Through its advanced construction and innovative technologies, the SDPX SumiDrill Power Series offers remarkably long tool life. The combination of sophisticated coating, optimized cutting edge design, and improved chip evacuation enables uninterrupted, highly efficient drilling while reducing tool wear and failure.

Extended Tool Life of the MDA Drill Thanks to DLC Coating
The MDA drill series offers outstanding performance and durability due to its innovative features. The following highlights the key aspects of extended tool life achieved through the special DLC coating.

What is the DLC Coating?
The DLC (Diamond-Like Carbon) coating is a diamond-like carbon layer characterized by its high hardness and low friction. This coating reduces wear and prevents the adhesion of materials such as non-ferrous metals to the cutting edge.

Benefits of the DLC Coating for Tool Life
Reduced Adhesion: The smooth surface of the DLC coating minimizes the adhesion of materials such as aluminum or other non-ferrous metals to the cutting edge. This ensures a smooth cut and fewer interruptions.

High Hardness: The diamond-like structure provides the drill with exceptional wear resistance, resulting in a longer service life.

Low Friction: The low coefficient of friction reduces heat generation during drilling and protects the tool from thermal damage.

Consistent Performance: The coating ensures that wear resistance remains low initially and then gradually increases, enabling consistent performance over a longer period.

Technical Properties of the MDA Drill
Diameter Range: 1.0–12.0 mm
Length Ratios: 3 to 20 x D
Internal Coolant Supply: Supports heat dissipation and improves efficiency.

Application Areas
The MDA drill is particularly suitable for:
- Aluminum Alloys
- Non-Ferrous Metals
- Plastics such as PMMA or Polycarbonate.

MDE MultiDrill NeXEO's advanced hard coating technology sets a new tool life and efficiency benchmark. The innovative AlTiSiN multi-layer coating provides exceptional wear resistance, holding up even under demanding conditions such as high temperatures and abrasive materials. This coating minimizes cratering and notch wear, ensuring high process reliability throughout the tool's life.

Benefits of the Coating Technology:

Extended Tool Life: Combining a high-hardness substrate and specialized coating significantly extends the tool's lifespan.

High-Temperature Resistance: The coating maintains its hardness even under extreme machining conditions, ensuring consistent performance.

Increased Efficiency: Fewer tool changes and regrinds lead to reduced production times and costs.

In addition, the MDE MultiDrill NeXEO features an optimized cutting-edge geometry that improves drilling precision and facilitates chip evacuation. This makes it ideal for applications where both precision and durability are critical.
