This M8 version uses an 8.4mm smaller cutting diameter to produce the clearance hole while the 15mm larger cutting stage simultaneously machines the 90° screw-head counterbore. Combining both operations in one tool helps reduce tool changes and maintains accurate concentricity between the clearance hole and the larger recess.\u003c\/p\u003e\r\n\r\n\u003cdiv class=\"definition-products\"\u003e\r\n\u003cstrong\u003eWhat is a subland drill?\u003c\/strong\u003e A subland drill is a multi-diameter twist drill incorporating separate cutting sections on a single tool. It allows a smaller clearance hole and a larger screw-head recess to be produced during the same operation. The Maykestag Code 841 is designed for clearance holes of accuracy class “medium” according to ISO 273 together with simultaneous 90° screw-head counterboring of shapes A and B, accuracy class “medium”, according to DIN 74 Part 1.\r\n\u003c\/div\u003e\r\n\r\n\u003ch3\u003eProduct highlights\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eHSS construction:\u003c\/strong\u003e High-speed steel provides the toughness, cutting performance and wear resistance required for professional drilling applications.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eSubland geometry:\u003c\/strong\u003e Produces the clearance hole and larger screw-head recess during one machining operation.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eM8 configuration:\u003c\/strong\u003e Combines an 8.4mm clearance-hole diameter with a 15mm larger cutting diameter.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eDIN 8374-FEIN:\u003c\/strong\u003e Manufactured to the specified fine-series subland drill standard.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eRN-fine geometry:\u003c\/strong\u003e Fine RN cutting geometry developed for controlled drilling and accurate stepped-hole production.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003e118° drill point:\u003c\/strong\u003e Conventional drill-point geometry on the smaller cutting section for controlled penetration.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003e90° counterboring:\u003c\/strong\u003e Larger cutting stage produces the specified 90° screw-head recess.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eSpecial point shape A:\u003c\/strong\u003e Catalogue-specified special point geometry for the Code 841 range.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eSTEAMED treatment:\u003c\/strong\u003e Surface-treated finish specified by Maykestag for the Code 841 range.\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eStraight shank:\u003c\/strong\u003e Precision cylindrical shank for secure holding in suitable drilling and machining equipment.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cdiv class=\"knowledge_box\"\u003e\r\n\u003ch3\u003eWhy Choose Maykestag?\u003c\/h3\u003e\r\n\u003cp\u003eMaykestag is an Austrian cutting-tool brand focused on precision-manufactured tools for professional drilling and machining applications. Accurate geometry is particularly important with a subland drill because the smaller drilling section, larger cutting stage and transition between the two must work together to produce a correctly aligned compound hole.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe \u003cstrong\u003eCode 841\u003c\/strong\u003e range combines HSS construction, DIN 8374-FEIN geometry and accurately controlled stepped diameters in a single tool.

The smaller cutting diameter enters the workpiece first and produces the clearance hole, followed by the larger cutting stage which machines the screw-head recess. Maykestag specifies that the cutting speed should be governed by the larger diameter, while the feed must be selected to suit the smaller diameter.\u003c\/p\u003e\u003csection\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003c!--  ===== Features and Benefits TAB ===== --\u003e\r\n\u003ch3\u003eFeatures\u003c\/h3\u003e\r\n\u003cul class=\"sideline-bullet\"\u003e\r\n  \u003cli\u003e\n\u003cstrong\u003eTwo diameters in one tool:\u003c\/strong\u003e Drills the clearance hole and machines the larger screw-head recess in one operation.\u003c\/li\u003e\r\n  \u003cli\u003e\n\u003cstrong\u003eM8 clearance-hole geometry:\u003c\/strong\u003e 8.4mm smaller cutting diameter combined with a 15mm larger cutting diameter.\u003c\/li\u003e\r\n  \u003cli\u003e\n\u003cstrong\u003e90° screw-head counterboring:\u003c\/strong\u003e Designed for simultaneous counterboring of shapes A and B according to DIN 74 Part 1.\u003c\/li\u003e\r\n  \u003cli\u003e\n\u003cstrong\u003eHSS with STEAMED treatment:\u003c\/strong\u003e Professional high-speed-steel construction with Maykestag's specified steamed surface finish.\u003c\/li\u003e\r\n  \u003cli\u003e\n\u003cstrong\u003eDIN 8374-FEIN RN-fine design:\u003c\/strong\u003e Precision geometry specifically developed for subland drilling applications.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eRecommended Applications\u003c\/h3\u003e\r\n\u003cp\u003eThe Maykestag \u003cstrong\u003eCode 841 range\u003c\/strong\u003e is rated by Maykestag according to its suitability for different material groups.
