All Industrial 1-2-3 Block Pair 23 Hole and 1/8 10 pc.Thin Parallel Set

Description

The All Industrial 1-2-3 block pair 23 hole set combined with the 1/8″ 10-pc thin parallel set is a comprehensive precision tooling combo engineered for machinists, toolmakers, and quality engineers who require uncompromising accuracy in setup, fixturing, and inspection operations. The 1-2-3 precision block pair with 23 holes is manufactured from premium precision-grade tool steel, heat treated and case hardened to HRC 57–62 for exceptional wear resistance and dimensional stability in demanding production and inspection environments. Each block in this machinist 1-2-3 block and parallel set is precision ground on all six sides, delivering accuracy and squareness within .0001"–.0002" to ensure reliable part setup and consistent measurement reference. The 23-hole precision block for fixturing features five 3/8-16 threaded holes for secure, positive clamping and 18 untapped through-holes, offering maximum versatility across a wide range of fixturing and workholding configurations. A cross-drilling design reduces block weight without sacrificing structural integrity, making the 1-2-3 block set easy to handle during frequent workstation repositioning. At the standard industry dimensions of 1" x 2" x 3", this parallel block set is compatible with magnetic chucks, sine plates, CMM fixtures, and a broad range of precision setup tooling currently in use across machine shops and inspection labs. Paired with the 1/8" thin parallel set for milling and grinding, this combination provides a complete workholding solution for lifting and positioning workpieces accurately above machine tables. The thin parallels, 1/8″–10 pc workholding set, include 10 pairs spanning heights from 1/2" to 1-5/8" in graduated 1/8" increments, covering a wide range of workpiece elevation requirements in milling, grinding, and surface grinding operations. Each thin parallel measures 1/8" thick x 6" long and features two holes for easy extraction with a pin punch during setup, minimizing downtime and setup time between operations. The 1/8″ 10-pc thin parallel set achieves flatness and parallelism within ±.0003″, ensuring repeatable, precise part elevation that directly contributes to dimensional accuracy in finished workpieces. Made from high-quality tool steel, the parallels are stress relieved against distortion, precision ground, and hardened for a long service life with minimal wear under high-cycle use. The precision 1-2-3 block pair for setup and inspection supports narrow work and small-diameter stock that standard-width parallels cannot accommodate, expanding the range of workpieces that can be effectively fixtured. A balanced grain and resin density across both the blocks and parallels ensures a controlled, consistent response on harder metals while reducing loading on softer workpiece materials. The complete All Industrial 1-2-3 block pair 23 hole set and thin parallel set combo ships in a durable plastic case available in red or blue, protecting all components from damage during storage and transport. The machinist's 1-2-3 block and parallel set is a must-have investment for any precision machining or inspection workstation seeking accuracy, versatility, and durability. Choose the All Industrial 1-2-3 block pair 23 hole set combo for a foundational precision tooling solution that serves every stage of the machining and inspection workflow.
