Robbjack C07-0781-08-20 Slitting Saw 3/4 in Carbide 20T

Product Description

The ROBBJACK C07-0781-08-20 is a solid carbide slitting and slotting saw designed for precision cutting in metalworking and machining applications. With a 0.75 inch blade diameter and a 0.0781 inch blade thickness, this saw delivers tight, accurate slots and cuts in demanding materials. The 20-tooth straight configuration combined with a 5-degree rake angle and concave ground geometry provides clean chip evacuation and consistent cut quality. It mounts via an arbor connection and is supplied in a bright, uncoated finish. Machinists and tool and die professionals working in job shops, production facilities, and tool rooms are the primary users of this tool.

This saw is suited for slitting, slotting, and parting operations on a range of ferrous and high-performance metals. The solid carbide construction supports work in cast iron, stainless steel, carbon steel, super alloys, and titanium. Its right-hand cutting direction makes it compatible with standard milling machine and horizontal arbor setups. The combination of a thin kerf, carbide substrate, and concave grinding makes it a practical choice for applications where dimensional accuracy and edge quality in the slot are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard-metal cutting
• 0.0781 inch blade thickness for tight-tolerance slotting and parting operations
• 20 straight teeth with a 5-degree rake angle for controlled chip load and smooth cutting action
• Concave ground blade geometry improves clearance and reduces friction during the cut
• Bright, uncoated finish suitable for use with cutting fluids across a broad range of materials
• Right-hand cutting direction for standard milling machine arbor setups

Compatibility

Designed for use on horizontal milling machines and arbor-driven setups where an arbor-mount slitting saw is required. Material compatibility includes cast iron, stainless steel, carbon steel, super alloys, and titanium as stated by the manufacturer.

Installation Notes

Installation is performed by a machinist on a milling machine or similar arbor-driven spindle. Ensure the machine is fully powered down and locked out before mounting or removing the saw from the arbor. Use the correct arbor diameter and proper saw arbor spacers to center the blade and maintain runout tolerances. Always confirm spindle rotation direction matches the right-hand cutting orientation of this tool before engaging a cut.
