Mitsubishi MZS02656LB VP15TF 26.56mm Through-Coolant Solid Carbide Drill

The Mitsubishi Materials MZS02656LB is a new, solid carbide through-coolant twist drill from the DIAEDGE MZS series, ground in grade VP15TF — a PVD-TiAlN-coated ultrafine-grain carbide specifically engineered for high-speed drilling of stainless steels, alloy steels, and difficult-to-cut materials. Decoded from the MPN: MZS = series designation (MZS short-flute or long-body through-coolant drill), 026 = 2.6 mm nominal diameter × 10 (i.e., 26 mm diameter family prefix) — more precisely, "02656" encodes the diameter as 26.56 mm, LB = long body (extended flute length variant), and VP15TF = the carbide grade/coating. The drill body features internal through-coolant channels visible at the tip in the product photo, a 140° split-point geometry optimized for self-centering entry without a pilot hole, and a two-flute helical design with a TiAlN PVD coating that provides thermal hardness retention above 800 °C for extended tool life at aggressive feed rates. Made in the USA (as labeled), this drill accepts standard cylindrical shank toolholders and is compatible with Mitsubishi's MZS-series modular drill bodies or direct-chuck setups on machining centers equipped with through-spindle coolant delivery.
