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

A NC centre drill Ø 8 mm for position-accurate and rapid drilling on CNC machines and drilling rigs, offering combined centring and chamfering in one operation with a DIN 6535-HA cylindrical shank.

• Solid carbide for high cutting stability
• 8 mm diameter with 90° tip angle
• Cylindrical shank to DIN 6535-HA
• Centres and chamfers in one pass

Accurate starts and reliable hole guidance for automated production

The combination of a 90° tip angle and a rigid solid carbide body delivers consistently precise starts, reducing wander at the outset of drilling operations. As a dedicated centre drill, it provides secure guidance for subsequent twist drills and machining steps, improving overall process reliability. The cylindrical shank to DIN 6535-HA ensures repeatable clamping in tool holders and spindles, which is essential for serial production on CNC centres and drilling rigs. This results in fewer rejects and less rework in high-precision environments.

Versatile performance across demanding materials

Designed for demanding applications, the tool is optimised for high-strength steels, steel castings, grey cast iron, stainless steels and various non-ferrous metals. The right-hand cutting geometry and solid carbide construction enable stable cutting conditions even under elevated loads; a recommended feed in steel up to 800 N is 0.1 mm/rev, which balances tool life and cycle time. Explaining the benefit: using a centre drill that matches the material and feed guidance minimises burr formation and prepares a correctly centred entry for accurate thread starts or deeper machining operations.

Seamless integration into CNC workflows and efficient shop-floor handling

With a DIN 6535-HA shank and compact overall length, the tool is straightforward to program into tool lists and to handle in automated tool-change systems. The shortened spiral length aids chip evacuation during the initial engagement, while the h6 tolerance on diameter supports tight concentricity demands. For production planners, this means reduced set-up time and consistent part quality across batches. Spare tooling and replacements are easy to specify thanks to clear dimensional data, so downtime is reduced and throughput maintained.

FAQ

What materials is this centre drill suitable for?
The NC centre drill from TECWERK is suitable for high-strength steels, steel castings, grey cast iron, stainless steels and a range of non-ferrous metals.

How should the tool be clamped for best accuracy?
Clamp the cylindrical shank in a holder compatible with DIN 6535-HA to ensure repeatable concentricity and secure clamping during CNC operations.

What feed is recommended for steel applications?
A feed of 0.1 mm/rev in steel up to 800 N is recommended for a balanced combination of tool life and process stability when using this TECWERK centre drill.

Can the tool perform centring and chamfering in a single pass?
Yes, the geometry allows for position-accurate centring and light chamfering of tapped holes in one operation, reducing machining steps.
