The Monster Tool 36XF12 (also labeled 460-101260B) is a new, solid carbide twist drill measuring 1/8 in (0.125 in) in diameter, finished with an AlTiN (Aluminum Titanium Nitride) coating for elevated hot hardness and oxidation resistance up to approximately 800 °C — making it well-suited for hardened steels, stainless steels, cast iron, and high-temperature alloys. Monster Tool is a GWS Tool Group brand known for premium solid carbide rotary cutting tools manufactured to tight tolerances; the "XF" designation in the part number indicates an extra-fine grain carbide substrate, which increases toughness and edge retention at small diameters. The drill features a standard 118° split-point geometry visible in the photos, a straight shank sized to the drill diameter for use in collet chucks, Jacobs-style drill chucks, and quick-change tool holders accepting 1/8 in round shanks, and two-flute spiral construction for efficient chip evacuation in CNC machining centers and drill presses.
