At 4.20 mm (0.1654 inches) in diameter with a 55.00 mm (2.17 inches) overall length, this bit is built for rigidity and reduced deflection in short-reach setups. The 135-degree split point geometry allows self-centering on contact, eliminating the need for a center punch on most materials. Two regular-spiral flutes clear chips efficiently during drilling operations. The heavy-duty cobalt construction handles harder workpiece materials and elevated heat better than standard high-speed steel bits.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are used in drill presses, CNC machines, lathes, and hand-held power drills where reduced length improves stability or where spindle clearance is limited. This bit is well suited for production drilling in metal fabrication, maintenance and repair, and mechanical assembly environments. The straight shank fits standard drill chucks. The right-hand cutting direction is standard for conventional drilling operations. The straw finish is a light heat-treatment coating that provides modest lubricity and corrosion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.20 mm (0.1654 inch) diameter with a short 55.00 mm (2.17 inch) overall length for rigidity in tight setups\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers on contact and reduces walking without a center punch\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides heat resistance for drilling harder and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTwo regular-spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade classification for demanding production and repair applications\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard screw machine length drill bit with a straight shank for use in any drill press, CNC spindle, lathe tailstock, or hand-held drill chuck accepting bits in the 3.50 mm to 5.00 mm (0.1500 to 0.2000 inch) size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, tool and die workers, and maintenance technicians. Secure the straight shank fully in the drill chuck and verify concentricity before drilling. Power down and de-energize the machine before changing bits. Do not exceed the recommended speed and feed for the workpiece material when using cobalt bits, and use appropriate cutting fluid where the material and application call for it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 55.00 mm (2.17 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00 mm\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01195734\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715735978290,"sku":"01195734","price":86.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eac366a350c36458532e3cdf61f4b921.jpg?v=1788517840","url":"https:\/\/voomisupply.com\/products\/value-collection-01195734-screw-machine-drill-bit-4-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
