TECWERK NC Spot Drill, Ø12 mm HSS‑Co, 120° Point

The TECWERK NC Spot Drill, Ø12 mm, is a cylinder‑shank spot drill engineered for position‑accurate spot‑drilling and simultaneous centring and chamfering on NC machines and boring mills.

• HSS‑Co for extended tool life
• Ø12 mm for accurate, repeatable positioning
• DIN 1835‑A cylinder shank for standard holders
• 120° point for precise centring and chamfering

High‑precision performance for NC workflows

The solid‑cobalt high‑speed steel construction (HSS‑Co) provides a robust cutting edge that balances wear resistance with economical regrinding intervals, making it suitable for serial tasks on automated equipment. With its Ø12 mm geometry and 120° point, the spot drill minimises wander at the drill entry and establishes a reliable centre for subsequent operations. This targeted geometry reduces rework and setup time, improving overall process throughput on production lines and toolrooms.

Combine centring and chamfering in one operation

Designed to centre and chamfer threaded holes in a single pass, the tool streamlines workflow on NC drilling machines and boring mills. The integrated chamfer function delivers a clean lead‑in for taps while the centring action secures positional accuracy, which together reduce handling and cycle time. The right‑hand cutting geometry supports standard spindle directions used in machining centres, ensuring predictable chip flow and consistent hole quality.

Compatibility and mounting for secure toolholding

Equipped with a DIN 1835‑A cylinder shank, the spot drill fits a broad range of standard holders and collets, simplifying integration into existing tool assemblies. The cylinder shank format enables quick tool changes and stable clamping, which is critical when machining to tight tolerances. The specification for feed in steel up to 800 N at 0.1 mm/rev provides a clear operational envelope for planners and operators, facilitating reproducible cycle planning and safe process parameters.

Practical handling and workshop benefits

The combination of a hardened cutting grade and a precise point angle allows for dependable results across repetitive tasks without complex parameter tweaking. Regrinding intervals are extended by the cobalt alloy, while the robust point geometry reduces the likelihood of surface irregularities at the hole entry. For workshops seeking a pragmatic balance between tool life and machining speed, this spot drill offers measurable gains in consistency and uptime.

FAQ

What materials is this spot drill intended for?
The TECWERK NC Spot Drill is specified for use in steel applications; the tool’s HSS‑Co grade and the stated feed parameter (feed in steel up to 800 N: 0.1 mm/rev) indicate suitability for typical steel machining tasks.

Will the shank fit common toolholders?
Yes — the tool features a DIN 1835‑A cylinder shank, which is compatible with standard holders and collet systems designed for that shank profile.

Can this tool centre and chamfer a threaded hole in one operation?
Yes — the design explicitly combines centring and chamfering of thread holes in a single pass, reducing setup time and improving cycle efficiency.

Why does the point angle matter for centring?
The 120° point creates a stable entry geometry that minimises axial deflection at the drill entry; this improves initial positioning and helps ensure consistent hole quality for subsequent drilling or tapping operations.

What feed rate should be used for steel?
The recommended parameter from the technical specification is 0.1 mm/rev for a steel feed force up to 800 N, which provides a reliable starting point for process planning with this spot drill.
