It features a variable helix design with an aggressive 35-degree helix angle that transitions to 15 degrees, promoting rapid chip evacuation and reducing heat buildup at the cutting edge. The 135-degree split point tip starts on contact without a center punch and eliminates bit walking. A Chip Breaker geometry further manages heat to help the cutting edge stay sharp through demanding production drilling cycles. Licensed contractors, maintenance mechanics, and metal fabricators working in commercial or industrial settings rely on this bit for consistent, repeatable results in tough material.\u003c\/p\u003e\n\u003cp\u003eThe 48-89-2510 is suited for jobsite and shop drilling in hard and exotic metals where standard high-speed steel or black oxide bits wear prematurely. The metric sizing makes it compatible with metric hole-tolerance work. The Secure Grip shank geometry resists slipping in both keyed and keyless chucks, supporting use in corded drills, drill presses, and magnetic base units common in structural steel and fabrication applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix geometry — 35-degree aggressive angle transitions to 15 degrees for rapid chip removal and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003e135-degree split point tip starts on contact, no center punch required, eliminates walking\u003c\/li\u003e\n  \u003cli\u003eChip Breaker design limits heat accumulation to extend cutting edge life\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction provides up to 10 times the service life versus black oxide bits in hard metal applications\u003c\/li\u003e\n  \u003cli\u003eSecure Grip shank prevents slipping in keyed or keyless chucks\u003c\/li\u003e\n  \u003cli\u003eMetric sizing for metric hole-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit for use in standard keyed and keyless drill chucks accepting round-shank bits; suitable for corded drills, drill presses, and magnetic base drilling units used in hard metal and structural steel applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the bit fully in the chuck before operating and confirm the chuck is tightened on the Secure Grip shank flats. Use appropriate cutting fluid or coolant when drilling stainless steel or high-alloy materials to extend bit life and control heat. Ensure workpieces are clamped securely before drilling to prevent movement. Wear appropriate PPE including eye protection per ANSI Z87.1 standards when operating any rotary cutting tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Length\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Packaged)\u003c\/strong\u003e: 5.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees (aggressive) transitioning to 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSplit Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Cobalt steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSizing Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 045242519408\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-2510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51342711456050,"sku":"48-89-2510","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310512824.jpg?v=1782004312","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2510-cobalt-jobber-drill-bit-3-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
