Filetta Prism set MS910.459 — 90° paired-ground prisms (4–38 mm)

The Filetta Prism set MS910.459 is a compact 90° inspection prism set designed for precise clamping and alignment of shafts, bars and cylindrical parts in fine mechanical work and workshop metrology

• Paired-ground contact surfaces
• Accuracy ±0.005 mm
• 90° geometry for shaft alignment
• Hardened 52–57 HRC

Repeatable geometry for precise clamping and inspection

The prism geometry delivers a stable seating angle and consistent support for cylindrical components, making repeatable checks straightforward in routine inspection tasks. The ground faces, delivered paired-ground, ensure matching contact planes that reduce rocking and local stress during clamping. With a measured accuracy of 0.005 mm and parallelism 0.005 mm, the design converts precise geometry into reliable tactile reference points for alignment and measurement workflows, reducing setup iterations and increasing throughput on the shop floor.

Wear resistance and surface finish engineered for longevity

Surface finish and material hardness determine how long a measuring aid retains its geometry under regular use. These prisms are hardened to 52–57 HRC, a range that balances resistance to wear with toughness against impact during handling. The paired-ground finish also minimises contact area irregularities, so long-term repeatability is preserved. For workshop environments where abrasion and repeated clamping occur, this combination extends service life and maintains metrological performance without frequent reconditioning.

Practical range and accessories for workshop readiness

Covering a measuring span of 4–38 mm, this set sits in the micro-range for fine mechanical work where compact support and high accuracy matter most. Included items such as the clamping strap and measuring stop make the set immediately usable for setup, inspection and small-jig assembly tasks. The compact dimensions suit bench-top use and inspection fixtures, offering an alternative to bulky v‑blocks when space or access is limited. The measured range and included accessories streamline integration into daily quality-control routines.

Why this solution supports efficient measurement processes

By combining matched contact surfaces, clear numeric specifications and workshop-ready accessories, the unit offers an evidence-based route to faster, more reproducible measurement cycles. The defined 90° angle aids alignment tasks while the documented 0.005 mm accuracy supports decision-making in tolerance-sensitive assemblies. For production environments seeking predictable outcomes, these properties translate into fewer reworks and a steadier quality flow.
