Sandvik Coromant 5749507 Square Milling Insert H10 Carbide

Product Description

The SANDVIK COROMANT 5749507 is a solid carbide milling insert designed for precision metal removal in demanding machining applications. Manufactured to H10 grade with a bright uncoated finish, this insert suits operations where coating-free carbide performs best, particularly in non-ferrous and cast iron workpieces. The square insert geometry features four cutting edges, a positive rake angle, and a honed cutting edge style for clean, controlled cuts. At 0.5 inches inscribed circle and 0.125 inches thick, it fits standard SFA-series toolholders. A 25-degree relief angle reduces tool pressure on the workpiece. Maximum depth of cut reaches 0.3543 inches, making it suitable for both finishing and moderate roughing passes. Licensed machinists and CNC tooling specialists are the primary installers of this insert type.

This insert is intended for milling cast iron and non-ferrous metals, including aluminum alloys and copper-based materials. The SFA series design and right-hand cut orientation make it a direct fit for toolholders requiring ANSI code SFA 42E3 R H10 or ISO code SFAN 12 03 EF R H10. It performs in both horizontal and vertical milling configurations on CNC machining centers and manual knee mills. The flat-top chip breaker geometry is well-suited for applications where chip control in softer or gummy non-ferrous materials is a priority.

Key Features

• Square insert shape with four usable cutting edges for extended tool life per insert
• Positive rake angle with honed edge style for reduced cutting forces and clean surface finishes
• 25-degree relief angle minimizes rubbing and tool pressure during cut
• Maximum depth of cut of 0.3543 inches suitable for moderate stock removal
• Meets ANSI and ISO standards; ANSI code SFA 42E3 R H10, ISO code SFAN 12 03 EF R H10
• Clamp-style insert holding method for secure, repeatable seating in the toolholder

Compatibility

Designed for SFA-series toolholders requiring ANSI code SFA 42E3 R H10 or ISO code SFAN 12 03 EF R H10. Insert size code 42 with a 0.5-inch inscribed circle. Right-hand cut orientation. Single-sided insert with a 90-degree included angle.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct clamp and torque driver specified by the toolholder manufacturer — do not over-torque the clamping screw, as this can fracture the carbide. Inspect the insert pocket for chips or debris before seating to ensure full, flat contact with the insert.
