BHJ Flycutter Head
BHJ Flycutter Head Carbide and CBN Cutters

Part No: FCH-2 FCH, FCH2

BHJ's Flycutter Head makes fast work of surfacing cylinder heads and blocks and adds versatility and value to your existing milling machine for all types of general machining operations.

The Flycutter Head is supplied with both a Carbide Cutter for machining aluminum (lower left) and a CBN Cutter for use on cast iron (lower right). The CBN Cutter Insert enables speeds and feeds of more than three times that of carbide inserts when used on cast iron.

Tests conducted in our factory indicate a .005" depth of cut on a cast iron Big Block Chevrolet head can be performed in four and a half minutes using the CBN Cutter. The single-cutter design allows quick changing from carbide to CBN cutting without losing the ability to cut quickly and accurately.

The 7" diameter body can be adjusted to cut from 9" to 12" diameters and the 15-pound weight of the head acts to dampen the cutting operation, resulting in a smooth, chatter-free cut.

Recommended initial settings are 500-RPM Speed, .005" Depth and 5" per minute Feed. Speed and Feed can be varied from that point, based on results.

An R-8 style Arbor is included standard, which allows the Cutter will fit the spindle of most vertical mills. Other Arbor styles are available as well and can be quoted on request.
