Extension for Screw‑In Cutter VT502TM — 100 mm overall length, M8 thread (Teknik Makina)

The Extension for screw‑in cutter VT502TM is a purpose‑built holder extension that increases machining reach for screw‑in milling cutters while maintaining run‑out stability in workshop and light industrial applications

• Secure M8 threaded connection for reliable mounting
• 16 mm shank for rigid machine tool clamping
• Compatible with 14 mm cutter openings
• 100 mm overall length for extended reach

Increased reach with retained rigidity for precision machining

This extension is engineered to extend the working envelope of screw‑in milling cutters without compromising stability. The 100 mm overall length provides extra reach for recessed features and hard‑to‑access geometries, while the 16 mm shank maintains a robust clamping interface to reduce vibration and run‑out. The M8 threaded joint is standardised, giving a tight mechanical coupling that supports consistent tool positioning; this reduces setup iterations and contributes directly to higher first‑pass accuracy in series and single‑piece production.

Quick fitting and secure interface explained

Fitting is straightforward: the extension accepts cutters with a 14 mm cutter opening and seats against the tool via a 30 mm cone engagement, ensuring axial alignment. The 30 mm cone length acts as a guiding seat that centres the insert‑style cutter, while the M8 thread secures axial load transfer during milling. For machinists unfamiliar with threaded cutter systems, the combination of a locating cone and fine mechanical thread means fewer adjustments are required at the machine, shortening preparation time and improving throughput on repetitive tasks.

Practical benefits for workshop and jobbing environments

Designed for everyday use in workshops and small production facilities, the extension combines lightweight handling (approx. 0.153 kg) with mechanical reliability. The compact mass reduces additional inertia on the spindle in hand‑operated setups and portable machines, which is beneficial where delicate control of cutting forces is required. By choosing a purpose‑made extension rather than ad‑hoc adaptors, shops gain predictable performance and reduced risk of tool failure, supporting a continuous production flow and consistent surface finish quality.

FAQ

What cutter types fit this extension? The extension accepts screw‑in milling cutters designed for a 14 mm opening; the locating cone and M8 thread provide a secure seat for standard screw‑in cutter systems such as those used in light milling operations.

Is the extension compatible with my collet or holder? Compatibility depends on the machine’s toolholder accepting a 16 mm shank; the extension’s 16 mm diameter is intended for holders and collets rated for that shank size and will give a rigid connection when correctly clamped.

How does the 30 mm cone length benefit accuracy? The 30 mm cone engagement centres the cutter axially before the thread is tightened, improving concentricity and reducing run‑out compared with non‑locating adaptors; this supports repeatable machining results.

Can the extension be used for long overhang operations? The 100 mm overall length increases reach but also raises bending moment; the extension is optimised for moderate overhangs where the 16 mm shank still provides sufficient stiffness for accurate cuts.
