It measures 25\/64 inch (0.3906 inch) in diameter with an overall length of 5-23\/64 inches (5.3594 inches). The 140-degree split point geometry reduces walking and lowers entry force, making it well-suited for hard and abrasive workpiece materials. A TiAlN (titanium aluminum nitride) coating extends tool life by improving heat resistance and reducing built-up edge. The right-hand, regular spiral flute design promotes efficient chip evacuation. This bit is rated as a high-performance grade and features coolant-through capability for use in CNC and production drilling setups. Typically installed and operated by machinists and metalworking professionals in shop environments.\u003c\/p\u003e\u003cp\u003eThis jobber drill is optimized for drilling stainless steel and similarly hard ferrous and non-ferrous alloys where standard high-speed steel bits lose cutting edge quickly. The 5xD flute-to-diameter ratio provides adequate flute length for through-hole applications in moderate-thickness stock. Coolant-through construction supports internal coolant delivery when used in compatible toolholding systems, helping maintain cutting temperatures during extended production runs. The straight cylindrical shank accepts standard drill chucks and collet systems without requiring special toolholding adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves thermal resistance and extends tool life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web reduces thrust force and prevents walking\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery in production setups\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute with 5xD ratio for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill for CNC machining centers, drill presses, and compatible toolholding systems accepting a 25\/64 inch straight shank.

Secure the straight shank fully in a compatible drill chuck or collet before operation and verify runout is within acceptable tolerance for the application. When using coolant-through capability, confirm the toolholder and spindle support internal coolant delivery at the required pressure. Follow all machine guarding and PPE requirements applicable to drilling operations in your facility.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-23\/64 inches (5.3594 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/32 inches (3.1563 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\u003ePoint Type\u003c\/strong\u003e: Proprietary (R-Thinned Web)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742611374386,"sku":"4500170","price":208.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cced5507ae5b6c52178bc9f43f1e397.jpg?v=1788838350","url":"https:\/\/voomisupply.com\/products\/accupro-4500170-jobber-drill-25-64-in-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
