4-Pair Precision Machinist's Parallel Set

Parallels are rectangular metal blocks. They are the machine setup tools made from tool steel or stainless steel which get 2, 4 or 6 faces ground or lapped to a precise surface finish. When machining with a mill, drill or any other machining operation that requires workpieces to be held in a holder like a vise or with clamps - to keep work parallel or raised evenly such as in a milling vise to give adequate height for the cutting tool/spindle to pass over, machinists look for precision parallels. The parallel set is sort of one-set for multiple jobs. 

All of Accusize machinist's parallel sets are made from high-quality alloy steel. They are ideal for layout work, standards, and set-ups for milling machines. Accusize parallels deliver operational excellence and performance efficiency to machine shop work. The holes on the parallels enable the parallels to be lighter, improving the efficiency of set-up.
