ITP VKM300004040 is a ceramic-stem stylus extension designed to extend metrology probes into hard-to-reach areas while keeping styli from interfering. Built for precision inspection and coordinate measuring machines, this compact 40 mm extension uses an M3 thread and a ceramic stem mounted on a stainless steel base for reliable, rigid performance.

• Thread Size: M3
• Overall Length: 40.0 mm
• Stem Material: Ceramic
• Base Material: Stainless Steel
• Shank Diameter: 4.0 mm
• Purpose: Extends reach into restricted work areas and isolates styli to minimize interference
• Material Benefits: Ceramic stem provides high rigidity and favorable thermal behavior for stable measurements

This extension helps you reach features inside pockets and recessed areas without disturbing nearby styli, while preserving measurement accuracy by reducing deflection and interference. The ceramic stem's stiffness and stable thermal behavior enhance consistency across temperature changes, and the stainless-steel base delivers durable mounting for demanding inspection environments. Ideal for CMM probes and other precision metrology workflows where space is tight and accuracy matters.
