ENGIS HONING SOLUTIONS FOR FIREARM COMPONENT BORES


Need Better Hole Precision in the Manufacture of Barrels, Gas Blocks & Triggers?

For years Engis has worked successfully with manufacturers of handguns, as well as sporting and military rifles, to improve product consistency, reliability and lower costs in both high and low production finishing of various firearms components.

State-of-the-art Engis bore honing brings best-in-class barrel quality achieving bore sizes within 2 microns, bore roundness under 2 microns and surface finish under 0.1 Ra and 1.0 Rz prior to rifling.

Additionally, Engis has successfully assisted small-scale manufacturers and high-end contract shops to reduce/replace reaming and ultimately bring down their broaching costs.

Benefits of single-pass technology include:

  • Improved straightness in the barrel
  • Better barrel roundness
  • A more uniform finish
  • Increased tool life vs reamers
  • Lower costs
  • Engis tools can be used on either soft or hardened metal barrels up to 20" in length
