NC centre drill D 6 mm, HSS‑Co, 120° – TECWERK

The NC centre drill D 6 mm, HSS‑Co, 120° is a specialist spot‑drilling tool for position‑accurate centring and simultaneous chamfering on NC machines and drill rigs

• HSS‑Co construction for enhanced wear resistance
• Cylindrical shank to DIN 1835‑A for machine clamping
• 120° tip for accurate centring and chamfering

Precise two‑in‑one operation reduces cycle time

This centre drill combines a rigid 120° point geometry with a short flute to enable fast, position‑accurate spot‑drilling and countersinking in a single pass. The tool’s geometry supports a consistent pilot and chamfer for threaded holes, which reduces setup steps and minimises repositioning. With a recommended feed of 0.05 mm/rev in steel up to 800 N, operators achieve predictable hole starts and repeatable results, improving throughput on CNC turning centres and drilling machines.

Durable cobalt high‑speed steel for longer tool life

Manufactured from HSS‑Co, the cutter offers improved red‑hardness and abrasion resistance compared with conventional high‑speed steels, making it suitable for demanding production environments. The tolerance h8 on the cutting diameter maintains concentricity in chucks or collets, while the spiral length 16 mm and overall length 66 mm balance chip evacuation with rigidity. These material and dimensional attributes translate into fewer tool changes and lower process variation over longer runs.

Secure mounting and straightforward integration on NC equipment

The cylindrical shank according to DIN 1835‑A ensures consistent clamping and accurate axial positioning in standard toolholders. Right‑hand cutting geometry provides conventional chip flow and predictable performance across common workpiece materials. Designed explicitly for NC operation, the tool supports automated cycles where positional accuracy for pilot holes and chamfers is critical, such as in serial tapping preparation and pre‑drilling stages.

Practical benefits for production and jobbing shops

By combining centring and chamfering, the tool simplifies workflows and reduces the number of operations per hole, delivering measurable time savings in batch work. The robust design and HSS‑Co composition make it a dependable choice for mixed‑material shops that require repeatable hole starts. Supplied with standard diameter tolerance and a machine‑friendly shank, the cutter eases fixture design and ensures rapid changeover in high‑throughput environments.
