Finish BORING HEADS: SERIES 111/112

KAISER 111/112 boring heads are designed for precision production boring on machining centers, jig mills, boring mills, transfer machines and high speed milling machines. Their fully enclosed, compact and rugged design allows reliable operation, even under extreme cutting conditions.

The KAISER 111/112 heads feature highly accurate and smooth micrometer adjustment precision. Each head is available with either inch graduations (.0002" on diameter) or metric graduations (0.005mm on diameter) easily read by large dials. The wide space between graduations allows diameter corrections of .0001" and finer. All tool carrier movement is strictly radial, making length corrections required on angular mounted boring tools unnecessary. The locking system prevents any diameter shift under locking action forces and maintains diameter under all cutting conditions, assuring of the highest repeatability.

A wide selection of reduction bushings, carbide or hardened steel boring bars, and replaceable insert holders assure optimum tool selection for nearly all bore diameters and depths. Through spindle coolant capability is standard on all 112 heads. The series 112 heads also feature a telescopic adjustment of boring bars into the head, allowing unrestricted setting length of each bore depth.

EWB 2-50 BORING HEAD : BALANCEABLE BORING HEAD

The KAISER EWB 2-50 boring heads maximize cutting speeds and feeds on small diameter bores due to an integrated counterweight, which allows for precision balancing of the tool assembly. By using charts that are applied with these boring heads, the graduated scale ring can be rotated to the correct setting to offset the unbalance of the various boring bar.inset holder combinations possible scale ring can be rotated to the correct setting to offset the unbalance of the various boring bar/inset holder combinations possible with this versatile system. Significant improvements to bore quality, surface finish, and tool life are all the result of balanced tooling.

NOTE: USE ONLY CARBIDE BORING BARS WITH SERIES EWB BORING HEADS!
