Machinist Essentials 1/8 Parallel Set 1-2-3 Blocks 3/8 Edge Finder

The 1/8 x 6 long 10 pair parallel set consists of precision-ground parallel blocks used to support & elevate workpieces on machine beds or setups. They ensure that the workpiece is held at a consistent height & parallel to the machine surface, crucial for accurate machining operations. The parallel set is made from fine quality precision ground & hardened tool steel that has been stress relieved against distortion. The tolerance is parallel to 0.0003 on 2 sides, top & bottom & the dimensions are within 0.001 allowance. The 2 hole parallels are provided in a fitted durable plastic case. Included are the following sizes: 1/8 x 1/2 x 6,1/8 x 5/8 x 6,1/8 x 3/4 x 6,1/8 x 7/8 x 6,1/8 x 1 x 6,1/8 x 1-1/8 x 6,1/8 x 1-1/4 x 6,1/8 x 1-3/8 x 6,1/8 x 1-1/2 x 6,1/8 x 1-5/8 x 6. The matched pair, 8 pc 1-2-3 Precision 23 Hole Block Set with socket screws & a hex key is versatile & can be used for a variety of purposes in machining setups. These blocks can be used as reference points for measurements, as gauge blocks for setting up tools or machines, & as parallels or spacers to support workpieces. The blocks are hardened & precision ground on all 6 sides with squareness on all sides within .0001 per inch. The holes consist of 5 tapped holes that are 3/8-16 for clamping & 18 untapped holes & it is also supplied with a fitted case. The 3/8 micro edge finder is commonly used in machining setups & assist in accurately locating the edges of a workpiece or a machine's reference point. Precisely position the cutting tool or workpiece in the machine's coordinate system, ensuring precise machining operations such as milling or drilling. It provides a simple & effective method for aligning workpieces or setting zero points for machining operations. The edge finder is hardened & ground all over & accurately locates the starting point for all types of machine work & jig boring. The edge finder accuracy is .0002 & it has a tip diameter of 0.200.
