V-695A Milling Extension with Collets (ER16M, ST20×150 mm) – Vertex

A V-695A milling extension with collets designed to extend tool reach for precision milling tasks and secure toolholding in metalworking environments.

• ER16M collet system for secure tool clamping
• ST20 shank, 150 mm extension length
• Supplied as a 10-piece set for uniform tooling
• Robust construction, total weight 1.3 kg

Secure precision for extended-reach milling

The milling extension offers a combination of ER16M collet clamping and an ST20 shank, providing stable tool retention when machining recessed features or deep cavities. The ER16 system is a widely used collet interface, offering fine radial clamping and reduced runout compared with generic clamping methods; this improves repeatability and surface finish on subsequent passes. By choosing an extension with a known collet standard, workshop planners preserve spindle balance and maintain cutting accuracy over multiple tool changes, which reduces rework and increases first-pass yield.

Consistent tooling that speeds up production

Supplied as a 10-piece set, the extension kit simplifies standardisation across fixtures and machines, cutting preparation time and minimising setup variance between operators. The designation ST20×150 mm denotes the shank size and the usable extension length, making it suitable for reaching deeper pockets without resorting to improvised solutions. The set's overall mass of 1.3 kg supports easy handling and organised storage while remaining substantial enough to dampen minor vibrations; the result is improved tool life and lower frequency of rebalancing.

Practical handling and maintenance for reliable uptime

The design emphasises user-friendly maintenance and secure clamping: the integrated collet arrangement ensures a repeatable grip and quick changeover when paired with standard ER16 collets. For routine care, periodic inspection of the collet and bore surfaces is recommended to avoid dirt-induced runout. The construction supports robust everyday use in production workshops; thanks to standard interfaces and consistent geometry, replacement planning and inventory control are simplified, which helps sustain machine availability and predictability in production scheduling.

FAQ

What does ER16M mean for toolholding?
The ER16M designation refers to the collet interface used by the V-695A extension; it indicates compatibility with ER16 collets, which provide precise radial clamping and low runout for improved machining accuracy.

Is the ST20×150 mm size suitable for deep-pocket milling?
Yes, the ST20 shank with a 150 mm extension length is intended to reach deeper features while maintaining tool stability when used with appropriate toolholders.

Does the set include collets and how many pieces are supplied?
The Vertex V-695A is supplied as a 10-piece set and is described as delivered with collets, enabling consistent tooling across multiple machines.

How much does the kit weigh and what does that mean for handling?
The complete set has a listed weight of 1.3 kg, which supports straightforward handling, storage and reduces the risk of accidental damage when configuring tool racks.

Can the extension affect spindle balance or runout?
When used with correctly sized ER16 collets and maintained interfaces, the extension minimises additional runout; regular inspection of the collet and bore surfaces is advised to preserve balance and repeatability.
