BRUCKNER DEAD CENTERS
HE, HL, HS AND GHS FORMS

Forms HE, HL, HS and GHS

Common Technical Features:
  • Roundness of Carbide:  Out-of-roundness - 0<0.001 (.00003")
  • Taper Shank of Tolerance:  The deviation of taper 'Z' is < AT4 (guage accuracy)
  • Out of Roundness:  Very narrow eccentricity 'V' of the 60° point to the taper shank
  • Hardened Taper Shank:  The taper shank is case-hardened for protection from damage
  • Carbide:  We use only top quality carbide to achieve maximum safety
  • Regrinding Line:  On the useful end of the carbide a usable limit is marked by a brazen line
