Fowler X-Blox X-Block Set 52-475-500-0 Universal Holding Tool

Description

Product Overview

The Fowler X-Blox X-Block Set, model 52-475-500-0, is engineered to meet the rigorous demands of precision machining, inspection, and calibration tasks. Crafted from high‑grade hardened steel, each block delivers a flat square surface and V‑groove that remain parallel within .0005″, ensuring that even the most delicate components are held with unwavering stability. The set includes two robust universal clamps, each designed to fit securely into the V‑grooves, providing a reliable grip for grinding, drilling, milling, or indexing operations. The clamps are housed in a shop‑hardened case that protects the tooling during transport and storage, extending the lifespan of the equipment. With dimensions of 1.5 x 1.25 x 1.25 inches and a weight of just 0.71 ounces, the blocks are compact yet powerful, making them an essential addition to any precision‑focused workshop.

Usage

Designed for versatility, the X‑Block Set excels in a variety of environments, from aerospace component assembly lines to small‑scale laboratory calibration stations. The precise square surfaces are ideal for aligning optical lenses, electronic connectors, and miniature mechanical parts, while the V‑grooves accommodate cylindrical workpieces ranging from 0.125″ to 0.250″ in diameter. The universal clamps enable quick setup changes, allowing technicians to transition from holding a tiny gear to securing a delicate sensor without the need for additional fixtures. Because the blocks are lightweight, they can be mounted on portable workbenches, jigs, or even handheld fixtures, providing flexibility for on‑site repairs and field inspections. Their durability also makes them suitable for high‑volume production environments where repeatability and consistency are paramount.

Why Choose Us

Choosing the Fowler X‑Blox X‑Block Set means investing in a legacy of quality that dates back to 1904, when the Fred V. Fowler Company first pioneered precision tooling for the burgeoning industrial market. Each block undergoes a rigorous heat‑treatment process that eliminates internal stresses, guaranteeing long‑term dimensional stability even after repeated use. The universal clamps are engineered with hardened steel jaws and a low‑friction pivot, delivering a smooth clamping action that reduces the risk of marring delicate surfaces. Our shop‑hardened case is not only a protective container but also a convenient transport solution, featuring molded slots that keep the clamps and blocks securely in place during travel. In addition, Fowler provides responsive technical support and a comprehensive warranty that covers manufacturing defects, giving you confidence that your investment is protected.

FAQ

What sizes of workpieces can the V‑grooves accommodate?

The V‑grooves are engineered to accept cylindrical parts from 0.125″ up to 0.250″ in diameter, making them suitable for a wide range of small components.

Can the universal clamps be used with other V‑block sets?

Yes, the clamps feature a standard geometry that fits most industry‑standard V‑blocks, allowing you to integrate them into existing setups.

How do I maintain the flatness of the square surfaces?

Regularly clean the surfaces with a lint‑free cloth and avoid exposing the blocks to corrosive chemicals. For extreme precision work, a light polishing with a non‑abrasive compound can restore surface finish without altering dimensions.

Is there a warranty on this product?

Fowler offers a one‑year limited warranty covering any manufacturing defects, and our technical support team is available to assist with installation, usage tips, and troubleshooting.

What is the best way to store the X‑Block Set when not in use?

Keep the set in the supplied shop‑hardened case, stored in a dry environment away from direct sunlight. This protects the hardened steel from moisture and preserves the precision tolerances.
