Mitsubishi 10542866 Carbide Drill Bit 11/32 in Tialn Mvs

Product Description

The MITSUBISHI 10542866 is a solid carbide extra length drill bit engineered for high-performance drilling in demanding metalworking applications. Sized at 11/32 inch (0.3438 inches) with a 145-degree drill point angle and X-Thinning point geometry, it is built to initiate clean cuts with minimal thrust. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. With a 1.630-inch flute length, 3.361-inch overall length, and a maximum drilling depth of 0.743 inches, this bit fits precision production and job-shop work where hole quality and tool consistency matter. It is part of the Mitsubishi MVS series, targeting high-precision and high-performance classifications. Licensed machinists, CNC programmers, and toolroom technicians are the primary users.

This drill bit is designed for cross hole drilling, through-hole drilling, stack drilling, and general drilling operations. Its primary workpiece material designation is Steel (ISO code P), with broad secondary compatibility across stainless steel, superalloys, titanium, structural steel, tempered steel, hardened steel, iron, cast iron, carbon steel, high-strength bronze, bronze, brass, copper, aluminum, and aluminum alloys. The coolant-through design makes it well-suited for use in CNC machining centers and precision drilling fixtures where internal coolant delivery is available. Right-hand cutting and right-hand spiral geometry are standard for conventional spindle setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• TiAlN coating for high-heat resistance and extended tool life at aggressive feed and speed parameters
• 145-degree drill point angle with X-Thinning and parallel web for reduced thrust and improved chip evacuation
• Coolant-through capability supports high-speed CNC operations and deep-hole thermal management
• Helical flute geometry with 2xD flute-to-diameter ratio for controlled chip flow
• Cylindrical shank at 0.394 inches diameter for standard collet or drill chuck fitment
• Right-hand cutting and right-hand spiral for use with conventional machine spindle direction

Compatibility

Designed for use in CNC machining centers and precision drilling equipment with coolant-through toolholding capability; suitable for cross hole, stack, and standard drilling operations in steel, stainless steel, superalloys, titanium, cast iron, aluminum, brass, bronze, and copper workpiece materials per ISO material classifications P, M, K, and N.

Installation Notes

This bit should be installed by qualified machinists or CNC technicians in a properly sized collet or drill chuck matched to the 0.394-inch shank diameter. Always ensure the machine spindle is fully stopped and the tool is securely clamped before beginning a cut. Verify that coolant-through pressure and flow rate are appropriate for the workpiece material and cutting parameters before initiating the drilling cycle. Do not use this bit in hand-held portable drills; it is intended for rigid machine-tool setups only.
