Built from solid carbide with a PVD-applied Tiger Tec coating in grade WXP40, this insert delivers wear resistance and thermal stability when drilling stainless steel and steel. It carries the P48448A57 designation, indicating a square shape, A57 chipbreaker geometry, and insert size code 48. With four cutting edges and a 90-degree included angle, the insert provides multiple index positions before replacement, reducing tooling cost per hole. Right-hand cutting direction is standard. Licensed machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for indexable drill bodies requiring a square P484-style insert with an inscribed circle of 0.6890 inches (17.50 mm). The A57 chipbreaker geometry is optimized for chip control in stainless steel and general steel applications, covering ISO material groups M and P at grades M30, P40, and S30. It is suited for production drilling environments where consistent hole quality and tool life are priorities. The ISO code for this insert is P4841C-8R-A57 WXP40, which can be used to verify fitment with compatible drill bodies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD Tiger Tec WXP40 coating for extended tool life in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eSquare shape with 90-degree included angle and four usable cutting edges\u003c\/li\u003e\n\u003cli\u003eA57 chipbreaker geometry for reliable chip control in M and P material groups\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 0.6890 inches (17.50 mm) and insert size code 48\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; meets ANSI and ISO standards\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0390 inches (0.99 mm) for controlled edge geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit indexable drill bodies accepting P484-style square inserts with an inscribed circle of 17.50 mm and insert size 8.
