Vertex V-698D milling extension with ER20M collets — ST25 x 150 L

The V-698D milling extension with ER20M collets is designed to extend tool reach for deeper milling operations while maintaining concentricity and machining stability in production environments

• ER20M collet compatibility for stable clamping
• ST25 x 150 L shank for extended reach
• Delivered as a set of 12 precision extensions
• Robust 1.5 kg mass for steady machining

Reach further without compromising stability

The ST25 x 150 L configuration provides additional reach where standard holders fall short, enabling access to recessed pockets and deep contours. This extension adds useful working length while aiming to preserve the original tool geometry, limiting the need for additional tool changes and saving cycle time. The resulting workflow improvement reduces interruptions during runs and supports smoother production sequencing.

Reliable clamping for consistent concentricity

Clamping is handled via the ER20M collet interface, a widely used collet standard that offers precise radial grip and repeatable centring. By combining a rigid collet system with a purpose-made extension, the assembly helps to minimise runout and maintain cutting-edge engagement, which in turn supports improved surface finish and prolongs cutter life. For non-specialist teams, a collet is a tapered sleeve that clamps the tool uniformly around its shank for stable rotation.

Set format to simplify inventory and production

Supplied as a set of 12, the configuration supports small-batch and continuous production by reducing procurement frequency and easing stock management. The set approach is particularly useful for shops that standardise on a small range of holder dimensions and need quick replacement options. With a total mass of 1.5 kg indicated for the item, handling and storage are straightforward, while the collective availability of multiple extensions reduces downtime caused by unexpected tool wear.
