Professional HSS-E Cobalt Spot Weld Drill Bit
This German-engineered HSS-E spot weld drill delivers precision removal of spot welds without panel damage. The 5% cobalt alloy construction and specialised grinding geometry enable clean, burr-free drilling through materials up to 900 N/mm . Designed for professional panel repair, this drill bit eliminates the risk of punching through thin metal while maintaining consistent cutting performance.
Engineered for Spot Weld Removal
The self-centering tip design prevents wandering on curved panels, while the straight main cutting edge provides rapid material removal without heat buildup. This two-flute configuration evacuates swarf efficiently, maintaining cutting speed through multiple spot welds. Compatible with both cordless and corded drills, it adapts to any workshop environment.
Technical Specifications:

Ideal Applications:
- Panel replacement Clean spot weld removal without adjacent panel damage
- Restoration work Precise drilling for separating factory-welded panels
- Collision repair Professional-grade results on modern high-strength steels
- Custom fabrication Drilling thin-walled materials without distortion
Why HSS-E Cobalt Matters
Standard drill bits overheat and dull quickly on spot welds. This HSS-E cobalt composition maintains hardness at elevated temperatures, ensuring consistent performance through entire panel sections. The cobalt alloy provides the durability required for drilling through modern automotive steels, including galvanised and high-strength variants.
Professional Drilling Technique
The self-centering point eliminates pilot hole requirements simply position on the weld centre and apply steady pressure. The specialised grind prevents breakthrough damage to underlying panels, critical when separating bonded assemblies. This controlled cutting action preserves panel integrity for precise reassembly.
Workshop Efficiency Benefits
Each spot weld drilled cleanly saves minutes of grinding and cleanup. The burr-free finish means immediate panel separation without secondary operations. When drilling dozens of welds per panel, this efficiency translates to significant time savings and superior finished results.
German Engineering Standards
Manufactured in Germany to exacting tolerances, this drill bit represents proper tool investment. The blank (uncoated) finish allows visual wear inspection while maintaining cutting geometry through repeated resharpening. This isn't a disposable tool it's workshop equipment built for years of professional use.
The Professional's Choice
Quality panel work demands precision tools. This HSS-E cobalt spot weld drill delivers the controlled cutting action, durability, and consistent results that separate professional repairs from amateur attempts. Whether you're restoring classics or repairing modern vehicles, this is the drill bit that gets panels apart cleanly.
Technical note: For optimal results, use cutting fluid on stainless steel and operate at recommended speeds for material type. The cylindrical shaft ensures compatibility with standard drill chucks from 3mm upward.
