It features a 140-degree four-facet point for accurate self-centering and reduced thrust on entry. The sub-micrograin carbide substrate provides the hardness and wear resistance needed for high-performance drilling in ferrous and non-ferrous materials. Coolant-through construction delivers coolant directly to the cutting zone, supporting higher feed rates and helping evacuate chips from deep holes. Right-hand spiral flutes with web thinning round out a geometry built for productivity.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for precision hole-making in machining centers, CNC drilling operations, and manual machine tools where a straight-cylindrical shank is used. The 5xD flute-to-diameter ratio and 43 mm maximum drilling depth make it appropriate for through-hole and moderate-depth blind-hole work in a production environment. Machinists, toolroom technicians, and CNC operators working in job shops or manufacturing facilities will find this bit appropriate for high-volume runs in steel, stainless, cast iron, and similar materials where TiAlN coating performance is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid sub-micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-heat cutting environments\u003c\/li\u003e\n\u003cli\u003e140-degree four-facet point promotes accurate self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers cutting fluid directly to the drill tip\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry reduces cutting forces and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with 5xD flute-by-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in machine tool spindles and CNC machining centers accepting a straight-cylindrical shank with an 8 mm shank diameter.

Use a collet or drill chuck rated for the 8 mm straight-cylindrical shank diameter and torque the retention mechanism according to the toolholder manufacturer guidelines. Verify coolant-through passages are clear and that the machine tool coolant system is compatible before use. Inspect the cutting edges for chips or wear before each setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide (Sub Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: 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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 91 mm (approximately 3.58 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (approximately 2.09 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (approximately 0.315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (approximately 1.42 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43 mm (approximately 1.69 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.30 mm (approximately 0.051 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.097 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EMUGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TA213344.0635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":52070453379378,"sku":"TA213344.0635","price":238.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f8c2d26757e1ead923bcb9805ce7b8c_71870ba5-42f1-43ea-a6e8-4291fa2027d6.jpg?v=1790048498","url":"https:\/\/voomisupply.com\/products\/emuge-ta213344-0635-carbide-drill-bit-letter-e-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
