NC spot drill Ø4 mm, solid carbide, TiAlN coating — TECWERK

A NC spot drill Ø4 mm designed for position-accurate and rapid spot drilling on CNC machines and drilling rigs, enabling centring and chamfering of thread holes in a single operation.

• Solid carbide, TiAlN coating
• 142° point for precise centring
• Cylindrical shank to DIN 6535-HA
• Suited for high-strength and stainless steels

Longer tool life through hard-wearing materials

The combination of solid carbide substrate with a TiAlN coating delivers superior wear resistance and thermal stability compared with uncoated tools. This increases tool life under intermittent and continuous operation and permits higher cutting parameters where the machine allows. Operators will notice fewer tool changes, reduced downtime and more consistent hole quality, as the protective coating helps resist abrasion and adhesion when machining abrasive or heat‑sensitive materials.

Faster, more accurate centring and chamfering in one pass

A 142° point angle and optimised geometry enable reliable centre formation and a controlled chamfer during a single cycle. The cylindrical shank DIN 6535-HA ensures rigid clamping and concentric running on CNC spindles and drilling rigs, improving repeatability and reducing runout. Combined with right-hand cutting and the specified feed behaviour, the design reduces secondary operations and shortens cycle time while maintaining hole position accuracy.

Built for a wide range of demanding materials

The tool is specifically prepared for machining high-strength steels, grey cast iron, stainless steels and non‑ferrous metals, making it a versatile choice for workshop and production environments. By providing a clean, centred entry, the spot drill stabilises subsequent twist drills and enhances thread formation. For materials requiring delicate heat control, the coated surface lowers friction and helps preserve edge geometry, supporting consistent performance across different alloys.

Practical performance data and process benefits

With an overall length of 50 mm and a spiral length of 12 mm, the configuration balances reach with rigidity for repeatable centring tasks. A recommended feed example is 0.06 mm/rev in steel up to 800 N, which gives a practical starting point for process setup; adjustments should be made according to machine capability and coolant use. The tool’s dimensions and h6 tolerance assist in predictable toolholders and accurate axial positioning, reducing setup time and scrap rates on precision jobs.

FAQ

What materials can this spot drill machine reliably?
The TECWERK NC spot drill is suited to high-strength steels, grey cast iron, stainless steel and a range of non‑ferrous metals, as stated in the technical features.

Is the shank compatible with standard toolholders?
Yes. The cylindrical shank complies with DIN 6535-HA, providing reliable clamping and concentricity for standard holders used on CNC machines and drilling rigs.

What is the recommended feed for steel machining?
A practical guideline is 0.06 mm/rev in steel up to 800 N; final settings should be adapted to machine stiffness, coolant and workpiece fixture.

Can this spot drill prepare holes for subsequent solid carbide drills?
Yes. The centring geometry provides an accurate starting point for twist drills; it is particularly compatible with solid carbide drills that have a 120–140° point angle.
