With a 29\/64-inch (0.4531 inches) diameter and a 140-degree split point, it delivers clean, accurate entry with reduced thrust. The TiNAl coating extends tool life in abrasive and hard materials. At 4.016 inches overall length, the screw machine format suits short-reach, high-cycle applications in machining centers and drill presses. Two flutes and coolant-through capability support chip evacuation and thermal management during extended cuts. Licensed machinists and tooling professionals install and deploy this bit in production and job shop settings.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for universal tool performance across multiple workpiece materials including cast iron, hard materials, non-ferrous metals, and steel. It is well suited for automated machining cells, CNC drilling operations, and manual drill press work where consistent hole quality and tool longevity are priorities. The straight-cylindrical shank fits standard collet chucks and drill chucks accepting a 0.472-inch shank diameter. Its screw machine length format makes it ideal for fixture drilling and confined-reach operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiNAl coating reduces heat buildup and extends tool life in ferrous and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle minimizes thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal chip flushing and heat control during deep cuts\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chuck systems\u003c\/li\u003e\n\u003cli\u003eScrew machine length format optimized for short-reach, high-cycle production drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series DC150-03-A1 screw machine length drill bit suitable for workpiece materials including cast iron, hard material, non-ferrous metal, and steel.

Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable limits for the application. Engage coolant supply before drilling when using the coolant-through feature. Never exceed the maximum drilling depth of 1.575 inches without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 29\/64 inches (0.4531 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 11.51 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.016 inches (102 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.165 inches (55 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.472 inches (12 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.770 inches (45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.575 inches (40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.082 inches (2.09 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiNAl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC150-03-A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.273 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: WALTER-TITEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6968840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51736005738802,"sku":"6968840","price":200.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c421e884831b1dd1234335822842515_f5bfbbb6-dce6-4c0f-ba62-f8bffb234500.jpg?v=1788775378","url":"https:\/\/voomisupply.com\/products\/walter-titex-6968840-screw-machine-drill-bit-29-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
