INSIZE M4

INSIZE is a metrology brand that manufactures dimensional measurement and inspection equipment, including calipers, micrometers, indicators, height gauges, and coordinate measuring machine (CMM) accessories. The INSIZE M4 line consists of straight CMM styli that use an M4 threaded stem and a ruby ball tip. These styli are consumable probing components for CMM touch probes, used to contact workpiece surfaces during dimensional inspection and quality control. The M4 thread size is a common interface for CMM probe heads and extensions, allowing the stylus to be mounted directly or combined with adapters and extensions to reach specific feature locations. Ruby is used for the ball tip because of its wear resistance and low thermal expansion, which helps maintain ball roundness and diameter stability over repeated contact cycles. The straight stylus geometry is intended for general-purpose probing where the approach vector is unobstructed and the feature can be reached without articulation. 3G Electric supplies the INSIZE M4 line as individual SKUs, with each stylus identified by its manufacturer part number and ball tip diameter. The range includes ball diameters from 0.04 in to 0.24 in, covering common probing needs from small holes and narrow slots to general surface and edge measurements. Each stylus is a ball-type, straight configuration with an M4 stem thread. The ruby ball tip is the contact element; the stem and thread provide the mechanical interface to the probe. These styli are used in industries where dimensional verification is part of production or incoming inspection, such as automotive components, aerospace parts, medical devices, and general precision machining. 3G Electric supports the INSIZE M4 line with global logistics, product data, and quotation services. The catalog includes 17 SKUs in this family, with specifications such as ball diameter, stem thread, and manufacturer part number listed for each item. Buyers can compare available sizes and request a quote directly. Because the styli are consumables, replacement planning and spares availability are relevant to maintenance and quality teams. 3G Electric provides access to the INSIZE M4 styli as part of its broader industrial equipment offering, which includes burners, pumps, gas controls, and related components. The company serves plant engineers, maintenance managers, and procurement specialists who need to source measurement accessories alongside other plant equipment. For CMM styli, the key selection variables are ball diameter, stem thread, and overall length or reach; the INSIZE M4 line provides a set of straight ball styli with M4 threads and ruby tips in multiple diameters. 3G Electric lists each SKU with its manufacturer part number to support cross-referencing and repeat ordering. The product data includes the type (ball, straight), stem thread size (M4), and ruby ball tip diameter in inches. This allows a buyer to match an existing stylus or select a size for a specific measurement task. The styli are intended for use with M4 CMM touch probes. They are not probe heads or complete measurement systems; they are the contact accessory that mounts to the probe. As with any precision probing accessory, handling and storage affect performance, and the ruby ball should be kept clean and free of damage. 3G Electric provides the INSIZE M4 styli with global shipping and support for quotation and order processing. The line is part of the company's catalog of industrial equipment and measurement accessories, and the 17 SKUs cover a range of ball diameters for common CMM probing applications.

Frequently asked questions

Common questions about INSIZE M4 from 3G Electric.

What is the INSIZE M4 stylus used for?

The INSIZE M4 stylus is a straight ball-type stylus for coordinate measuring machines (CMM). It mounts to an M4 CMM touch probe and provides the contact point for dimensional inspection. The ruby ball tip touches the workpiece surface, and the probe records the contact position. These styli are used in quality control and inspection tasks where features such as holes, slots, surfaces, and edges need to be measured. The M4 thread is a common interface, so the stylus can be used with compatible probe heads and extensions. 3G Electric supplies the INSIZE M4 line as individual SKUs with manufacturer part numbers for repeat ordering.

What ball tip diameters are available in the INSIZE M4 line?

The INSIZE M4 straight CMM styli listed by 3G Electric include ruby ball tip diameters of 0.04 in, 0.08 in, 0.2 in, 0.236 in, and 0.24 in. Each SKU has a specific ball diameter and an M4 stem thread. The ball diameter affects the probing application: smaller balls are used for small holes and narrow features, while larger balls are used for general surfaces and edges. The manufacturer part numbers for these items include ISQ-40-141, ISQ-40-195, ISQ-40-240, ISQ-01-4060-100SCE, ISQ-40-245, ISQ-40-179, ISQ-40-222, and ISQ-40-106. 3G Electric lists the ball diameter and part number for each SKU to support selection and cross-referencing.

Why do INSIZE M4 styli use ruby ball tips?

Ruby is used for the ball tip because it is wear-resistant and maintains its shape and diameter over repeated contact with workpiece surfaces. This is relevant for CMM probing, where the ball tip is the contact element and any wear or deformation can affect measurement consistency. Ruby also has low thermal expansion, which helps maintain dimensional stability under normal inspection room conditions. The INSIZE M4 styli in the 3G Electric catalog are ball-type, straight styli with ruby tips and M4 stem threads. They are intended for use with M4 CMM touch probes. The ruby ball should be kept clean and free of damage to support reliable contact measurements.

What does the M4 thread mean on an INSIZE stylus?

The M4 thread refers to the stem thread size that connects the stylus to the CMM probe head or extension. M4 is a metric thread size, and it is a common interface for CMM touch probes. The INSIZE M4 styli have an M4 stem thread, so they can be mounted to compatible M4 probe heads and accessories. When selecting a stylus, the thread size must match the probe interface. The INSIZE M4 line is identified by the M4 stem thread in the product specifications. 3G Electric lists the stem thread size for each SKU, along with the ball diameter and manufacturer part number, to help buyers confirm compatibility with their existing CMM setup.

How does 3G Electric support the INSIZE M4 product line?

3G Electric supplies the INSIZE M4 straight CMM styli as individual SKUs with manufacturer part numbers and specifications. The catalog includes 17 SKUs in this family, covering multiple ruby ball tip diameters and M4 stem threads. Buyers can compare available sizes, review product data, and request a quote. 3G Electric provides global logistics and order processing for these styli, which are consumable probing accessories. For procurement and maintenance teams, this means access to replacement styli and spares as part of a broader industrial equipment catalog. The product data includes type, stem thread size, ball tip diameter, and manufacturer part number to support repeat ordering and cross-referencing.

Are INSIZE M4 styli compatible with any CMM probe?

INSIZE M4 styli have an M4 stem thread and are designed for M4 CMM touch probes. Compatibility depends on the probe head interface: the probe must accept an M4 threaded stylus. Many CMM probe systems use M4 as a standard thread, but buyers should confirm the thread size and any required extensions or adapters for their specific probe model. The INSIZE M4 styli are straight ball-type styli with ruby tips, so they are intended for contact probing where the approach is unobstructed. 3G Electric lists the stem thread size and ball diameter for each SKU to help buyers match the stylus to their probe and measurement task.
