NC centre drill Ø 8 mm, solid carbide, 90° — TECWERK

The NC centre drill Ø 8 mm, solid carbide, is designed for position‑accurate and rapid spotting and chamfering on CNC machines and drilling rigs

• Solid carbide with 90° tip
• Cylindrical shank to DIN 6535‑HA
• Right‑hand cutting for fast centring
• Suited to high‑strength steels and stainless steel

Faster, more accurate holes in a single operation

The solid carbide construction and 90° tip enable precise centre holes and clean chamfers in one operation, reducing cycle times and lowering setup overhead. The combination of a hard cutting edge and a rigid body minimises run‑out and vibration, which delivers consistent hole geometry across batches. For operations requiring repeatable positioning—such as pre‑drilling for tapping—this tool reduces the need for secondary chamfering, improving throughput and part quality.

Built for CNC and conventional drilling machines

Engineered with a cylindrical shank to DIN 6535‑HA, the tool mounts reliably in standard tooling holders and collets used in CNC machining centres and drilling machines. The right‑hand cutting geometry provides predictable chip flow and stable cutting forces, supporting automated feeding strategies. These attributes make the tool a practical choice for production environments where tool changeover, clamping consistency and repeatability are essential.

Reliable performance on demanding materials

The geometry is optimised for a broad material spectrum: high‑strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals. The design supports a recommended feed of 0.1 mm/rev in steel up to 800 N, balancing cutting pressure and tool life. By choosing a carbide tool that handles tougher alloys, users benefit from extended service intervals and fewer tool replacements when machining challenging workpiece materials.

Time‑saving centring and chamfering for tapping operations

Combining centring and chamfering reduces handling and fixturing steps before thread forming. The tool locates the drill position accurately and deburrs the entrance chamfer in the same pass, which simplifies the process chain for thread preparation. This efficiency improves downstream thread quality and supports faster cycle times in serial production, particularly where multiple holes require identical preparation.
