The whole machine straight shank reamer with straight handle tungsten alloy reamer precision H7H8 has 5 specifications of uniform spot spot
We need different standard lengths to contact us!
The precision of each decimal point is made to order. Example 10.110.210.310.4.....10.9
Performance: suitable for processing high hardness quenching products, suitable for processing of chilled cast iron and alloy heat-resistant alloy steel, precision machining can also be suitable for ordinary iron, high wear resistance, good strength.
The accuracy level of machine reamer is: DD4H7H8H9
DD4 is the old standard, and H7H8H9 is the new standard.
The levels are: (high to low permutation) H7 > D > H8 > D4 > H9
Reamer tolerances are generally add size (commonly known as silk)
