TECWERK Spot‑weld Drill D8 × L79 mm — HSS‑Co, 8 mm shank

The TECWERK spot‑weld drill D8 × L79 mm is a purpose‑built spot‑weld cutter for precise, burr‑free extraction of resistance welds in workshop and production settings.

• HSS‑Co for enhanced heat resistance and life
• Conforms to DIN 1897 standard
• Self‑cutting centre tip for burr‑free results
• 8 mm cylindrical shank for standard chucks

Durable cutting performance for continuous use

The HSS‑Co base alloy provides a higher red‑hardness than conventional high‑speed steels, so the bit retains its cutting edge under elevated temperatures during intense drilling cycles. With a profile‑ground flute geometry produced to DIN 1897, the tool offers consistent chip evacuation and predictable wear behaviour, which supports stable process parameters and reduces the need for frequent tool changes. This combination translates into steady throughput and lower downtime in serial operations.

Clean spot‑weld removal with minimal finishing

A self‑cutting centre tip eliminates the need for a pilot hole, centring the drill on the weld nugget and initiating cutting without wandering. The right‑hand cutting geometry and the precision ground profile work together to produce burr‑free holes when removing spot welds, thereby reducing subsequent deburring or grinding operations. For workshops where surface quality and assembly fit are critical, this design lowers manual finishing time and improves part consistency.

Practical dimensions and straightforward workshop handling

With a nominal diameter of 8 mm and an overall length of 79 mm, the tool is compact yet long enough for most spot‑weld extraction tasks. The 8 mm cylindrical shank fits common 3‑jaw chucks and collet systems, enabling rapid changeover on bench drills and production machines. The robust construction and clear specification make the cutter suitable for integration into standard tool inventories, ensuring compatibility across a range of drilling equipment and simplifying procurement and stocking.

FAQ

What is the main application of this spot‑weld drill?
The TECWERK spot‑weld drill D8 × L79 mm is designed specifically for accurate, burr‑free extraction of resistance spot welds in sheet metal assemblies.

Which materials is the tool suitable for?
Made from HSS‑Co, the tool is intended for common sheet metal applications where spot welds occur; the cobalt alloy improves wear resistance under higher temperatures encountered during spot‑weld drilling.

Does the drill conform to an industry standard?
Yes, the cutter is manufactured to DIN 1897, ensuring consistent dimensions and compatibility with standard tool holders.

What ensures burr‑free results with this drill?
The combination of the self‑cutting centre tip and the profile‑ground flute geometry delivers centred engagement and controlled chip flow, which minimises burr formation during spot‑weld removal.

Which chuck or holder fits the shank of this drill?
The 8 mm cylindrical shank is compatible with standard 8 mm chucks and collet systems commonly used in bench and production drills.
