Built from solid carbide with a TiAlN finish, the bit delivers heat resistance and edge retention where standard-length tooling falls short. At 10.496 inches overall length with an 8.213-inch flute length, it provides the reach required for deep-hole drilling, cross-hole, and stack drilling operations. The 140-degree split point with X-thinning reduces thrust and improves centering at entry. Coolant-through capability supports chip evacuation and thermal control in high-feed cycles. Licensed machinists and CNC operators in metalworking shops are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for deep-hole drilling, cross-hole drilling, stack drilling, and general drilling operations. The 20xD flute-by-diameter ratio extends reach into deep bores. Its 0.3438-inch cutting diameter covers an 11\/32-inch nominal hole size. Secondary workpiece materials include stainless steel, superalloys, titanium, structural steel, tempered steel, iron, hardened steel, high-strength bronze, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloy. Primary application is steel cutting. Right-hand cutting direction and helical right-hand spiral are standard for conventional CNC and manual drill press setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN coating for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with X-thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and heat management in deep-hole cycles\u003c\/li\u003e\n\u003cli\u003e8.213-inch flute length and 20xD ratio provide access to deep bore applications\u003c\/li\u003e\n\u003cli\u003eHelical right-hand flute with parallel web configuration for consistent chip flow\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry balances rigidity and chip clearance for high-performance metal drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and drill presses capable of coolant-through delivery; compatible with toolholders accepting a 0.394-inch cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the drill. Verify coolant-through supply pressure and flow before initiating deep-hole cycles to prevent chip packing. Do not use this bit in underpowered or non-rigid setups that cannot maintain consistent feed force, as carbide tooling is brittle and sensitive to lateral deflection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3438 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 11\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 8.73 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.496 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.213 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 6.939 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.394 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.165 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 20xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITSUBISHI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10544150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51699138560306,"sku":"10544150","price":785.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_5a117b57-fcca-4bbc-b4be-3da83bf3ff65.jpg?v=1788372642","url":"https:\/\/voomisupply.com\/products\/mitsubishi-10544150-carbide-extra-length-drill-bit-0-3438-in","provider":"Voomi Supply","version":"1.0","type":"link"}
