Coated HSS Twist Drill Bits \u2013 M2, M35 & M42 Overview<\/h2>\n

This coated twist drill range brings together M2, M35 and M42 high-speed steel options for metal drilling. The supplied dimension chart groups cutting diameters from 0.5 to 20 mm into 28 bands, with overall lengths of 36\u2013205 mm and flute lengths of 14\u2013140 mm. Choose the steel grade, coating and point geometry for the workpiece and drilling conditions, then match the selected diameter to its listed length band. The chart does not identify a point angle, coating type or which material grades are available at each diameter; confirm those specifications for the ordered model.<\/p>\n

HSS Grade Selection<\/div>\n

M2, M35 and M42 are offered as grade options in the product title. Confirm the grade for the requested diameter and workpiece; M2 is not a cobalt grade.<\/p>\n<\/div>\n

\n
\u2195<\/div>\n
Size-Specific Lengths<\/div>\n

Each of the 28 diameter bands has a corresponding overall length L and flute length L1. Select by exact diameter and required reach.<\/p>\n<\/div>\n

\n
\u25c6<\/div>\n
Application-Matched Finish<\/div>\n

Confirm the coating or surface treatment for each ordered variant. The dimension chart does not name or assign a coating.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Key Product Advantages<\/h3>\n
\n
\n

Three HSS Grades<\/h4>\n

Review M2, M35 or M42 against the specific workpiece and tool configuration.<\/p>\n<\/div>\n

\n

Diameter Coverage<\/h4>\n

The supplied reference covers diameter bands from 0.5 to 20 mm.<\/p>\n<\/div>\n

\n

Length Reference<\/h4>\n

Check L and L1 for holder clearance and chip evacuation.<\/p>\n<\/div>\n

\n

Coated Options<\/h4>\n

Choose the actual coating with the material and process requirements in view.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Drilling Applications<\/h3>\n

These twist drills are intended for metal holemaking. Select the grade, point geometry and coating according to the workpiece, required hole size and depth, machine rigidity and available coolant. For stainless or other difficult materials, obtain a tool-specific recommendation rather than assuming every grade and coating has the same suitability.<\/p>\n

Application Note:<\/strong> L1 is the physical flute length, not a guaranteed drilling depth. Account for the point, chip clearance, tool holding and through-hole breakthrough when determining usable depth.<\/div>\n<\/section>\n
\n

Workpiece Material Selection<\/h3>\n

Provide the workpiece grade and hardness when selecting an HSS substrate and coating. Steel, stainless steel and other metal groups require different cutting conditions; the supplied dimension chart does not establish a material rating for every M2, M35 or M42 configuration.<\/p>\n<\/section>\n
