A new tangential milling system launched by Ringwood-based Horn Cutting Tools Ltd (www.phorn.co.uk) — and introduced at the recent AMB exhibition in Stuttgart — is said to be the first-ever side mill to feature six effective cutting inserts.

Moreover, this patented system offers positive cutting and axial rake angles for a particularly soft cut.

The precision-ground indexable inserts ensure a high level of accuracy and surface quality, while the addition of a free-form surface chamfer on the cutting edge creates a stable wedge.

In turn, this results in smooth milling and helps to extend tool life, while the surface treatment applied to the milling-cutter body gives it hardness and strength, ensuring long-term protection against abrasive chips.

The side milling cutter is based on Horn’s M610 system and is offered in two versions.

The first, which has a diameter of 100mm and five effective inserts in cut, has 10 inserts screwed onto the periphery on either side of the body.

The other version has a diameter of 125mm and uses 12 inserts to provide six effective cutting edges. The cutting width is 16mm on both versions, while the maximum groove depth is 34.5mm.

Indexable inserts are available with corner radii of 0.4mm or 0.8mm.

For the substrate, Horn has opted for the proven and tough AS4B.

The main body versions are available from stock as a side milling cutter with bore or as an arbour milling cutter.
