Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, this bit handles heat and wear far better than standard high-speed steel tooling. It measures 0.2500 inches (1\/4 inch, Letter E) in diameter, with a 135-degree split point for fast, accurate starts with minimal walking. The overall length is 2.5 inches, and the spiral flute length is 1.25 inches. Right-hand cutting with a straight cylindrical shank, it is suited for use in CNC machining centers, drill presses, and manual machine setups where consistent hole quality and tool life matter.\u003c\/p\u003e\u003cp\u003eThis bit is intended for machinists, tool and die professionals, and production shops working with hardened steels, stainless steel, cast iron, and other difficult-to-machine alloys. The screw machine (stub) length format offers increased rigidity compared to jobber-length bits, reducing deflection in short-reach drilling applications. The AlTiN coating raises surface hardness and oxidation resistance, making the bit effective at elevated cutting speeds and in dry or near-dry machining environments. Two spiral flutes promote efficient chip evacuation in both through-hole and blind-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating increases surface hardness and heat resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates the need for a center punch\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body provides superior rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and manual lathes or mills accepting a 1\/4 inch straight cylindrical shank.

Ensure the spindle and chuck are fully powered down before inserting or removing the bit. Carbide tooling is brittle and should not be subjected to impact or side-loading beyond the rated application. Follow machine tool manufacturer guidelines for recommended speeds and feeds when using carbide drill bits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/4 inch (0.2500 inches, Letter E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Aluminum Titanium Nitride)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC29016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51755083890994,"sku":"TC29016","price":76.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3203fcc2e68319048ff8eccaba37f48e_530cc849-e522-45c3-9001-5db1e282a62a.jpg?v=1788950963","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc29016-1-4-in-carbide-drill-bit-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
