O6

HARVI geometries for Duo-Lock target applications where solid carbide end mills are currently used. The Duo-Lock system combines the highest runout accuracy and length repeatability with maximum coupling stability. This enables the Duo-Lock system to use the full potential of Kennametal cutting geometries and grades with the flexibility of a modular system. Significant metal removal rates can be achieved. A wide range of diameters and corner configurations, such as chamfer, radii, and sharp edges, are available from stock. Cutting data and tool life comparable to high-performance solid carbide. Proprietary HARVI geometries enable roughing and finishing with one tool. 1,5 x D standard cutting edge length enables fewer passes. Up to 1 x D full slotting increases metal removal rates, increasing productivity significantly. Extensive offering of straight and conical shank tools, and integral adaptors that include DV, BT, and HSK.

Advanced Technology

New asymmetrical HARVI 4-flute geometry for higher feed-per-tooth rates. Variable helix design for chatter-free machining at high feed rates. Less pressure on cutting edge through tailored axial and radial rake angles. Eccentric relief design increases tool life through higher edge stability. Proprietary tapered core for highest tool stability when roughing and finishing.

Tailored Grades

KCSM15 Beyond grade for exceptional tool life in titanium and stainless steels. KCPM15 Beyond grade for outstanding wear protection in stainless steel to mitigate cratering, depth-of-cut notching, and flank wear. Universal KC643M grade for cutting steel, cast iron, stainless steel (wet), and titanium (wet).

Customisation

Intermediate diameters are available between 10-32mm. Chip divider geometry helps reduce power usage and improve chip formation in difficult-to-cut materials. Engineered solutions including shank and non-standard length versions available. Custom solutions within standard blank dimension are available.

Extensive Standard Offering

Diameter ranges 10-32mm. Necked, corner radii, chamfer, and square-end tips available. Integral adaptors to reduce interface for maximum accuracy. Steel extensions with Safe-Lock by HAIMER shanks to prevent pullout. Cut-to-size extra-long extensions available upon request off the shelf.
