Robbjack C40-2500-32-72 Slitting Saw 4 in 72T Carbide

Product Description

The ROBBJACK C40-2500-32-72 is a solid carbide slitting and slotting saw designed for precision cutting in demanding machining applications. Built in the Series C configuration, this saw measures 4 inches in diameter with a blade thickness of 0.25 inches and a 1-inch arbor hole. It carries 72 straight teeth with a concave ground profile, producing clean, accurate slots and slits in a right-hand cutting direction. At 0.0625 pounds, the saw is lightweight relative to its cutting capability. Solid carbide construction provides the hardness and wear resistance needed for high-performance milling operations across a range of difficult workpiece materials.

This saw is suited for use on vertical and horizontal milling machines in production and job-shop environments. It is appropriate for slitting, slotting, and parting-off operations where dimensional accuracy and surface finish are critical. The 72-tooth count and concave ground geometry make it a strong fit for fine-pitch slot work in ferrous and non-ferrous metals. Typical users include machinists and toolroom operators working with CNC mills, manual knee mills, and arbor-driven setups in industrial and aerospace manufacturing contexts.

Key Features

• Solid carbide construction for high hardness and extended tool life in abrasive materials
• 72 straight teeth with concave ground profile for clean slot geometry and reduced chatter
• 4-inch blade diameter and 0.25-inch thickness for precise slitting and slotting depth control
• 1-inch arbor hole for secure, concentric mounting on standard milling arbors
• Right-hand cutting direction compatible with conventional milling machine spindle rotation
• Bright/uncoated finish - no coating thickness to affect dimensional tolerances

Compatibility

Designed for use with standard 1-inch milling arbor setups. Rated for material applications including cast iron, stainless steel, steel, super alloy, and titanium.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's arbor assembly procedures. Ensure the spindle is fully stopped and the machine is locked out before mounting or removing the saw. Use the correct arbor spacers and draw bolt torque as specified by the arbor manufacturer to achieve proper seating and runout. Verify cutting direction and spindle rotation match the saw's right-hand configuration before initiating a cut.
