10mm NC Spot Drill HSS-Co 90° Right-Hand Cylindrical Shank, h8 Tolerance - TECWERK

Take advantage of fast, position-accurate hole starts and integrated chamfering thanks to the combination of a 90° centring point, HSS‑Co substrate and a DIN‑standard cylindrical shank; order directly via Metav Werkzeuge or consult our specialists for application advice.

NC spot drill D 10 mm, HSS‑Co, 90° – TECWERK

The NC spot drill D 10 mm HSS‑Co 90° TECWERK is a cylindrical‑shank spotting tool designed for precise centring and chamfering in a single pass on NC machines and drilling centres.

• Solid HSS‑Co for heat resistance and wear performance
• Cylindrical shank DIN 1835‑A for secure clamping
• 90° centring point for repeatable hole starts
• Tolerance h8 for consistent diameter fit

Faster, more reliable hole starts with integrated chamfering

High‑precision spot drilling reduces setup iterations and secondary operations. The 90° centring geometry enables exact alignment before subsequent drilling or threading, while the single‑pass chamfering capability eliminates a separate countersink cycle. This results in shorter machining times and fewer tool changes on production series. The combination of guided entry and chamfering supports reproducible part quality and lowers scrap rates in repetitive workflows.

Built for CNC and drilling centres — stable mounting, precise feeds

Compatibility with DIN‑specified toolholders is ensured by the DIN 1835‑A cylindrical shank, offering vibration‑resistant clamping in automated setups. The right‑hand cutting direction and defined feed guidance (feed in steel up to 800 N: 0.09 mm/rev) support consistent chip formation and predictable tool behaviour in programmed cycles. These characteristics make the tool suitable for integrated production cells where cycle reliability and process repeatability are decisive.

Longer service life through cobalt‑alloyed high‑speed steel

The HSS‑Co alloy increases red hardness and wear resistance compared with ordinary high‑speed steel, permitting higher thermal load before softening. This metallurgical advantage translates into stable edge retention and extended life in interrupted starts and tough entry conditions. For shops aiming to balance performance and tool cost, the cobalt alloy offers measurable improvements in cumulative running time and fewer unplanned tool changes.

Exact dimensions for dependable automation

Key dimensions and tolerances are engineered for predictable integration: a nominal diameter of 10 mm, overall length 89 mm, spiral length 25 mm and diameter tolerance h8. These specifications ensure a uniform locating fit and straightforward programming of Z‑axis depths. The short spiral length provides controlled chip evacuation during the initial engagement, supporting clean centring and reducing the risk of premature workpiece damage.

Productivity advantages on serial operations

Using a dedicated spotting tool streamlines the workflow: precise centring reduces rework, built‑in chamfering prepares holes for thread tapping in the same setup, and the robust substrate sustains longer runtime. The result is measurable throughput improvement for batch production and a lower total cost of ownership when evaluated across high‑volume cycles. For manufacturing environments where process time and traceable repeatability matter, a purpose‑designed spotting tool delivers immediate operational benefits.

FAQ

What materials is this spotting tool suitable for?
The TECWERK NC spot drill is manufactured from HSS‑Co, which provides enhanced heat resistance for reliable performance in standard steels and general workshop applications; material‑specific trials are recommended for specialised alloys.

Can the tool be used directly in standard cylindrical holders?
Yes, the DIN 1835‑A cylindrical shank allows secure clamping in holders designed for that standard, ensuring stable mounting in automated and manual setups.

How does the 90° point improve process reliability?
A 90° point provides a positive locating geometry for accurate centre positioning and controlled chamfering, reducing run‑out and the need for rework before drilling or tapping operations.

What feed values should be used as a starting point?
As a guideline, the tool supports a feed in steel up to 800 N of 0.09 mm/rev; final settings should be adjusted to machine rigidity and workpiece material for optimal chip control.

Is this tool suitable for preparing threaded holes in one operation?
Yes, the design enables centring and chamfering of threaded holes in a single pass, which helps to streamline the process and prepare the hole for subsequent tapping.
