Drill Fix DFT Side Inserts (A1 Heads, diameters above 31mm)

The DrillFix DFT inserts are engineered to improve edge toughness, lengthen tool life, and reduce depth of cut notching in a wide range of applications. The MD, DS, and HP carbide inserts are designed for use with KSEM PLUS™ A1 Heads, specifically targeting primary applications in steels, cast iron, and high-temperature alloys. They are particularly effective for outboard insert operations within a diameter range of 31.75-101.60 mm (1.250-4.000"). The DS insert geometry is optimized for longer chipping of steels and improving chip curling, breakage, and flow for smoother drilling processes. These advanced inserts are ideal for demanding industrial applications, ensuring precise and reliable performance.
