Tool Steel EN31 Deep Hardened Ultra Precision 1-2-3 Blocks (23 Holes) (4 Pairs (8 Pc))

Introducing the **Tool Steel EN31 Deep Hardened Ultra Precision 1-2-3 Blocks**—a premium set designed for exceptional durability and accuracy. This set includes 4 pairs (8 pieces) of 1-2-3 blocks, meticulously crafted from EN31 steel, which offers superior carbon and chromium content compared to mild steel. This results in enhanced distortion control and a longer lifespan, thanks to deep hardening in petroleum base oil, unlike the less effective hot water quenching used for mild steel. Each block features 23 precisely drilled holes, including 5 tapped holes, all achieved through advanced computer-controlled VMC machining for unparalleled accuracy. The blocks are precision ground with even chamfering on all six sides, ensuring smooth surfaces and reliable performance. Versatile in use, these matched pairs are ideal as step blocks, feelers, jigs, angle plates, and setup tools, making them a valuable addition to any machining setup.
