Description
Maykestag HSS Subland Drill M8 15 x 8.4mm DIN 8374 RN-Fine 90° Professional M8 HSS subland twist drill designed to produce an 8.4mm clearance hole together with a 15mm 90° screw-head counterbore in a single machining operation. Manufactured to DIN 8374-FEIN with RN-fine geometry, a 118° drill point and STEAMED surface treatment. The Maykestag Code 841 is a precision subland twist drill designed to machine two related diameters during one drilling operation. 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. What is a subland drill? 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. Product highlights HSS construction: High-speed steel provides the toughness, cutting performance and wear resistance required for professional drilling applications.
