Built from M42 cobalt high-speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and heat resistance beyond standard HSS tooling. The 135-degree split point reduces walking and allows drilling to start without a center punch. A parabolic flute geometry promotes fast chip evacuation and reduces cutting force in deeper holes. This is a heavy-duty, production-grade bit suited for machinists, fabricators, and maintenance trades working in metal-intensive environments.\u003c\/p\u003e\n\u003cp\u003eThe C16897 is appropriate for use in drill presses, CNC machines, and hand-held power drills where a straight shank and taper length are required. Material applications include aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. The taper length body provides additional reach compared to jobber-length bits, making it useful in applications where clearance or hole depth demands more flute exposure. This bit ships individually and is suited for single-use procurement or bench stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and improves surface hardness at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates drill walking on entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip evacuation in deeper cuts\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard 3-jaw chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe C16897 is compatible with drilling operations in aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel.

Secure the straight shank fully in the chuck before operation and verify runout is within acceptable tolerance for the application. Use appropriate cutting fluid or coolant for steel and stainless applications to prolong tool life. Inspect the cutting edges and TiN coating before each use and replace the bit if chipping or coating breakdown is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2575T\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 Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338, DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Applications\u003c\/strong\u003e: Aluminum, Brass, Carbon Steel, Cast Iron, Nickel Alloy, Plastic, Stainless Steel, Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51728544432434,"sku":"C16897","price":66.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eba04d07aa6ffc125ddd7eb3aa918bfc_bbf43c91-32cf-4f24-bcbd-1b94c45dd8b8.jpg?v=1788693059","url":"https:\/\/voomisupply.com\/products\/cleveland-c16897-taper-length-drill-bit-letter-e-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
