Drill bush DIN 179 form B, bore 33 mm, length 25 mm, outside dia 48 mm, case-hardened steel

The material, hardened to 740 ± 80 HV 10, keeps the 33 mm guide bore accurate even after many drilling cycles. The outside diameter measures 48 mm. Within the range this 33 mm bore is available in the lengths short, medium and long, here in the short version with 25 mm.
