The 135-degree split point tip starts cutting on contact, eliminating the need for a center punch and preventing the bit from walking across the workpiece surface. The Thunderbolt core construction is designed to resist breaking under the torque loads common in hard-metal applications. This bit is well-suited for electricians, plumbers, HVAC technicians, and fabricators who regularly drill through hard ferrous and non-ferrous metals on the job.\u003c\/p\u003e\u003cp\u003eThis cobalt drill bit is intended for use in stationary drill presses and handheld drills, including cordless platforms. It is a practical choice for trade professionals drilling through stainless steel HVAC components, pipe flanges, equipment enclosures, structural steel, and similar hard-metal substrates. The cobalt alloy construction retains cutting hardness at elevated temperatures, making it suitable for prolonged or repeated drilling cycles without rapid edge degradation. Sold as a single bit per unit of measure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point tip starts on contact with no walking and no need for a center punch\u003c\/li\u003e\n\u003cli\u003eCobalt alloy construction retains hardness at high cutting temperatures for extended bit life in hard metals\u003c\/li\u003e\n\u003cli\u003eThunderbolt core geometry resists bit breakage under high-torque conditions\u003c\/li\u003e\n\u003cli\u003eCompatible with cordless and corded drill drivers\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for hard metals including stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2 inch keyed and keyless drill chucks on corded or cordless drill drivers and drill presses.

Secure the bit fully in the chuck before drilling and verify chuck key is removed before powering the tool. Use appropriate cutting fluid or lubricant when drilling stainless steel or other hard metals to extend bit life and reduce heat buildup. Wear appropriate PPE including eye protection whenever drilling metal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Angle\u003c\/strong\u003e: 135 degrees split point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.66 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (EA)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE ELECTRIC TOOL CORP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-2329\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51525073404210,"sku":"48-89-2329","price":71.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ab76c243ed7d90c4bd220e629929016.jpg?v=1785463777","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2329-cobalt-drill-bit-1-2-inch-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
