Fine Boring

Our fine boring heads are great high precision finishing options for small, medium, and large diameter applications.

Carbide Bars

Tool combinations with carbide boring bars provide optimum rigidity when machining extremely long bores.

Fine O.D. Turning

Corresponding precision fine or rough boring heads and counterweights can be mounted on the tool holder either directly or by means of an extension.

Kits

These ready-to-go high-precision boring head kits provide everything you need to tool up for boring jobs in an extraordinary range of diameters.

Series 112 Balanceable Heads

Series 112 balanceable heads maximize cutting speeds and feeds on small diameter bores due to an integrated counterweight, which allows for precision balancing of the tool assembly.

Series 112 Components

A wide selection of reduction bushings, carbide or hardened steel boring bars, replaceable insert holders, and other attachments assure optimum tool selection for nearly all bore diameters and depths.

Series 112 Dial Heads

Fine boring heads in modular and integral execution for accurate, high performance boring operations on machine tools with spindles ISO 40, HSK-A63, BIG CAPTO C6 and bigger.

Series 112 Digital Heads

Digital fine boring heads in modular and integral execution for accurate, high performance boring operations. With wireless communication to the BIG KAISER app.

Series 309 Dial Heads

Diameter adjustments in the sub-micron range and balance qualities of G6.3 are requirements for tight tolerance bores with maximum RPM’s.

Series 309 Insert Holders

Modular insert holders for Series 309 EWB-UP boring heads.

Series 310 Auto-Balanceable Heads

Autobalance boring heads, Series 310 EWB, maintain perfect balance throughout the work range due to the integrated counter-balance mechanism.

Series 310 Dial Heads

The EWN single cutter boring tool program for finishing covers an impressive diameter range with only 7 precision boring heads.

Series 310 Digital Heads

Precision digital boring heads EWE and EWN, series 310 feature equal boring ranges and body dimensions and allow the use of the same accessories.

Series 310 Insert Holders

Insert holders and insert holder blanks with various approach angles suitable for various applications.

Series 470 Dial Heads

These fine boring heads can be clamped in BIG CAPTO shanks and other polygonal basic holders, or directly in BIG CAPTO machine spindles.

Smart Damper Heads

The integrated design of the Smart Damper system and EWN/EWD fine boring head shortens the distance from the damper and the cutting edge which is the source of vibration, so higher damping effects minimizes the chatter or vibration.
