TECWERK NC spot drill D 12 mm — solid carbide, 120° point

The TECWERK NC spot drill D 12 mm is a solid-carbide, right-hand pilot drill designed for precise positioning and simultaneous centring and chamfering of threaded holes on NC machines and drilling centres.

• Solid carbide, 120° point for precise centring
• Cylindrical shank to DIN 6535-HA
• Right-hand cutting for fast NC spot drilling
• Suitable for high-strength and stainless steels

Precision and time savings through combined centring and chamfering

The solid-carbide construction and 120° point deliver reproducible centre holes and short, concentric chamfers with minimal deflection. This tool combines the functions of a pilot and chamfer cutter, so a single operation prepares holes for threading and reduces setup changes. The DIN 6535-HA cylindrical shank ensures reliable clamping in standard tool holders, translating the tool’s rigidity directly into consistent hole placement. For production environments where cycle time and positional accuracy matter, this reduces secondary operations and lowers scrap rates.

Broad material compatibility for demanding workshop tasks

Built for demanding metalworking, the spot drill is particularly suitable for high-strength steels, steel castings, grey cast iron, stainless steel and non-ferrous metals, enabling one-pass centre and chamfer preparation even in challenging substrates. Used on NC machines and drilling centres, the tool’s geometry maintains chip control and secure entry when starting a bore, helping to avoid wander and burr formation. The ability to centre and chamfer in one pass improves workflow and reduces handling time for threaded-hole preparation.

Practical machining parameters and operational reliability

Designed as a right-hand, solid-carbide pilot, the tool performs best with conservative feeds and steady spindle control; guideline: feed in steel up to 800 N: 0.12 mm/rev. The solid-carbide (VHM) grade provides high stiffness and wear resistance, extending life under interrupted cuts typical of spotting operations. The tool’s profile supports clean entry and reduces the need for rework; routine inspection of clamping and cutting edges will preserve accuracy and repeatability. For bespoke applications, matching holder runout and machine rigidity to the tool’s diameter secures the best results.

FAQ

What machines is this spot drill intended for?
The TECWERK NC spot drill D 12 mm is designed for use on NC milling machines and drilling centres where accurate positioning and repeatable spotting are required.

Which materials can be machined with this tool?
Applications include high-strength steels, steel castings, grey cast iron, stainless steel and non-ferrous metals; the tool’s geometry supports clean entry and chamfering in these substrates.

What does VHM mean and why is it important?
VHM denotes solid carbide; this material provides higher stiffness and wear resistance compared with high-speed steel, improving dimensional stability during centre drilling.

How does the shank specification affect holder compatibility?
The cylindrical shank conforms to DIN 6535-HA, ensuring compatibility with standard collet and chuck systems and secure clamping for repeatable results.

What cutting data should be used as a starting point?
As a guideline, use a feed of around 0.12 mm/rev in steel up to 800 N and adapt spindle speed to material and machine rigidity; adjust parameters according to specific conditions and tool condition.
