Description

HHIP 9999-0057 1/8 x 6″ 10 Pair Precision Parallel Set & Matched Pair of 1-2-3 Blocks is a high-precision tool set designed for accurate workholding, setup, and measurement in machining and metalworking applications. This set combines 10 pairs of precision-ground parallels with a matched pair of 1-2-3 blocks, offering versatility and reliability for machinists and metalworkers. The included parallels and blocks are made from stress-relieved, hardened tool steel, ensuring minimal distortion, long-lasting durability, and exceptional accuracy.

Features:

Includes 10 pairs of 1/8″ thick precision-ground parallels in varying lengths from 1/2″ to 1-5/8″.
Parallels are made from high-quality tool steel, stress relieved to prevent distortion.
Tolerance: parallel to 0.0003″ on top and bottom surfaces; dimensions within 0.001″ allowance.
Matched pair of 1-2-3 blocks (1″ x 2″ x 3″) with 23 holes (5 tapped 3/8″-16, 18 untapped through holes).
1-2-3 blocks are case hardened to HRC 55-60, precision ground on all six sides for maximum squareness (.0002″ per inch).
Cross-drilled design of 1-2-3 blocks provides minimum weight with maximum strength.
Supplied in a fitted wood case for organized storage and easy access.

Benefits:

Ensures precise alignment, setup, and workholding for milling, drilling, and inspection tasks.
High accuracy and stability reduce errors in machining and measurement operations.
Durable, hardened tool steel construction provides long-lasting performance.
Versatile 10-pair parallel sizes and 1-2-3 blocks allow for a wide range of setups.
Convenient storage case keeps tools organized and protected.
