TECWERK Spot Weld Drill Ø8 × 44 mm — HSS‑Co, Vario shank

The TECWERK Spot Weld Drill Ø8 × 44 mm is a cobalt high‑speed steel drill designed for accurate, burr‑free removal of spot welds in sheet‑metal fabrication and repair.

• HSS‑Co for extended wear resistance
• DIN 1897 dimensions for industry fit
• Profile‑ground for precise cutting
• Self‑cutting centre for burr‑free holes
• Vario shank for secure clamping

Precision that reduces rework and maintains component integrity

Manufactured from HSS‑Co (cobalt‑alloyed high‑speed steel), this spot‑weld drill is built for elevated thermal stability and sustained edge retention during repetitive operations. The flute geometry is profile‑ground, which produces a consistent cutting action and reduces vibration; as a result, surface finish is improved and secondary deburring steps are minimised. Conformance with DIN 1897 provides dimensional reliability so that the tool fits common holders and machining setups without guesswork. These technical decisions translate directly into fewer rejects and lower rework time on the shop floor.

Clean, burr‑free holes that speed up assembly processes

Equipped with a self‑cutting centre and right‑hand cutting geometry, the cutter is optimised to remove spot welds precisely while producing minimal burr. The combination of a pointed centre and accurate cutting angles means the weld cap is opened and extracted rather than torn, which preserves surrounding material and reduces finishing effort. For workshops handling automotive panels, body repair, or light fabrication, this capability delivers faster cycle times and a more reliable fit for downstream joining or welding operations.

Robust clamping and straightforward integration into production

The Vario shank version provides secure seating in a wide range of chucks and holders, improving concentricity and reducing runout during use. With a straightforward Ø8 mm diameter and an overall length of 44 mm, the tool is compatible with many standard machining set‑ups and hand‑held drivers used in repair bays and light industrial environments. Specification choices were made for practical longevity: the material and geometry are engineered to balance tool life and cutting performance, offering an economical solution for medium‑volume production and specialised maintenance tasks.

FAQ

What materials can this drill be used on? The TECWERK Spot Weld Drill Ø8 × 44 mm is intended primarily for sheet‑metal assemblies and is optimised for removing spot welds without producing significant burrs.

Does the HSS‑Co alloy require special cutting speeds? Yes; the HSS‑Co composition used in this spot‑weld drill supports higher cutting temperatures and extended tool life compared with standard high‑speed steel, so cutting parameters can be adjusted for efficient removal while maintaining the tool’s lifespan.

Is the Vario shank compatible with standard chucks and holders? The Vario shank design is intended for secure clamping in common drill chucks and holders, ensuring good concentricity and reduced runout during operation.

Can the self‑cutting centre be resharpened? Resharpening options depend on workshop capabilities; the geometry of the self‑cutting centre is best maintained by professional regrinding services to retain the original performance of the TECWERK spot weld cutter.

What does DIN 1897 signify for this tool? DIN 1897 indicates that the tool’s dimensions and tolerances conform to a recognised industry norm, ensuring predictable fitment and interchangeability with standard tooling fixtures.
