Built from M42 cobalt high-speed steel, it carries a 135-degree split point that reduces walking on contact and lowers thrust requirements at the start of the cut. The parabolic flute geometry improves chip evacuation during deep-hole passes. At 3-3\/8 inches overall length with a 2-inch flute length, this stub-style bit fits low-clearance setups where a jobber-length bit would interfere. It cuts right-hand and is sized at 27\/64 inches (0.4219 inches decimal) with a straight cylindrical shank. Licensed machinists, tool and die technicians, and HVAC sheet metal fabricators are the primary installers.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling alloy steels, aluminum, and other materials that generate heat and work-harden under standard HSS tooling. The screw machine length format makes it a go-to choice for drill press work, CNC turret operations, and hand-held drilling in tight quarters. The M42 cobalt matrix provides added heat resistance over standard M2 HSS, making it appropriate for interrupted cuts and harder ferrous stock. The web-thinned, parallel web construction reduces the chisel edge load at entry, which extends bit life in production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat resistance in alloy and work-hardening materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and lowers entry thrust requirements\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes faster chip clearing in deeper holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces chisel edge load at drill entry\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 3-3\/8 inches OAL improves rigidity and fits low-clearance fixtures\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M standard with diameter tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks across drill presses, CNC turret lathes, and hand-held power drills.

Secure the shank fully in a properly sized drill chuck before operation and verify chuck key is removed before power is applied. Use appropriate cutting fluid for the workpiece material to manage heat, particularly when drilling alloy steels. Follow shop safety protocols including eye protection and secure workpiece clamping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inches (0.4219 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-3\/8 inches (34.92 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C15073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691415077170,"sku":"C15073","price":74.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3df712ae7837ba34c2aa39e0a778c1b_2fe2567a-d549-426a-a342-f9fa80a3c71d.jpg?v=1788284768","url":"https:\/\/voomisupply.com\/products\/cleveland-c15073-screw-machine-drill-bit-27-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
