BL-123NH 1x2x3 V Block by TFT Tools Heat Treated HRC 57-62 Steel

Description

Product Overview

The BL-123NH 1x2x3 V Block is a precision‑engineered component designed for the most demanding dimensional calibration tasks. Manufactured by TFT Tools, a reputable name in industrial measurement equipment, this block is fabricated from high‑grade tool steel that has been heat‑treated and case‑hardened to achieve a Rockwell hardness range of 57‑62 HRC. This hardness level ensures that the block maintains its shape and dimensional stability even under repeated use and exposure to harsh workshop environments. Each face of the block is ground to a tolerance of .0001‑.0002 inches, guaranteeing exceptional squareness and flatness across all six sides. The block measures exactly 1 inch by 2 inches by 3 inches, providing a versatile size that fits a wide range of inspection fixtures, jigs, and machining setups. Its compact package dimensions of 4.41 x 2.91 x 2.32 inches and a weight of 3.5 pounds make it easy to handle while still delivering the mass needed for stable positioning during precision work. The BL-123NH has been in production since February 13, 2005, and continues to receive positive feedback from professionals, reflected in a 4.6‑star rating from over 200 customer reviews. This V Block is not discontinued, ensuring ongoing availability for repeat orders and long‑term inventory planning.

Usage

Designed for use in a variety of industrial and scientific settings, the BL-123NH V Block excels in environments where exact dimensional control is critical. Machinists rely on this block to set up workpieces for milling, drilling, and grinding operations, using its precise angles to achieve consistent cuts and finishes. In inspection stations, quality‑control engineers employ the block as a reference surface for measuring the flatness and perpendicularity of components, ensuring that every part meets strict tolerance specifications. The block’s robust construction also makes it suitable for use in calibration labs, where it serves as a stable base for calibrating other measurement tools such as micrometers, dial indicators, and coordinate measuring machines (CMMs). Its heat‑treated, case‑hardened surface resists wear and deformation, allowing it to retain its calibrated dimensions over many years of service. Whether you are a small‑shop fabricator, a large‑scale manufacturing facility, or a research laboratory, the BL-123NH provides the reliability and accuracy needed to support high‑precision workflows.
