Spot‑weld drill Ø8 × 44 mm, HSS‑Co, Vario Drill — TECWERK spot‑weld drill for precise weld extraction

The Spot‑weld drill Ø8 × 44 mm, HSS‑Co, Vario Drill is designed for exact, burr‑free reaming of spot welds in production and repair workshops, combining standardised dimensions with a self‑cutting centre tip for reliable centring

• HSS‑Co for enhanced heat resistance
• DIN 1897 dimensions for compatibility
• Vario Drill shank with self‑cutting tip
• Profile‑ground for burr‑free spot‑weld removal

Consistent, measurable performance that reduces rework

Constructed from HSS‑Co, the drill delivers increased red‑hardness compared with standard high‑speed steels, which translates into sustained cutting performance under heat. The profile‑ground flutes maintain a precise cutting geometry that reduces vibration and produces a clean edge, so the operation results in burr‑free holes and fewer follow‑up dressing steps. Using a drill manufactured to DIN 1897 ensures dimensional compatibility with common holders and fixtures, supporting predictable throughput in repetitive workflows.

Engineered for precise centring and straightforward installation

A self‑cutting centre tip and cylindrical Vario Drill shank provide reliable initial contact and secure seating in compatible chucks. The right‑hand cutting geometry gives a conventional chip flow that is familiar to machinists and optimised for the intended application of spot‑weld removal. The shank design facilitates fast insertion and changeover in production settings, so line stoppages are minimised and setup times are reduced.

Durable finishing and clear technical advantage

The combination of cobalt‑alloyed steel and profile grinding increases resistance to wear and helps maintain the cutting edge over more cycles than plain‑high‑speed variants. This contributes directly to lower tool consumption and improved process economy: fewer tool changes and less scrap mean the operation becomes more cost‑effective over time. The resulting surface finish after drilling is suitable for subsequent welding or spot repair without extensive deburring.

Practical fit for workshop workflows and quality control

Designed specifically for precise extraction of spot welds, the drill supports quality‑focused workshops that prioritise repeatability and part integrity. The standardised geometry simplifies inventory management, while the controlled chip evacuation and centred entry reduce the risk of part distortion. For teams aiming to tighten tolerances and shorten cycle times, this solution offers a pragmatic balance of precision, durability, and operational ease.
