M35 Cobalt HSS Center Drills \u2013 TiN Coated Overview<\/h2>\n

These M35 cobalt high-speed steel center drills are offered with a TiN-coated finish for center-hole preparation and accurate hole starting. The supplied drawing shows a double-ended tool with 60\u00b0 and 120\u00b0 included-angle features. Its seven listed sizes cover cutting diameter d from 1.5 to 6 mm, shank diameter d1 from 4 to 14 mm and overall length L from 36.5 to 70 mm. Match the specified geometry and tool size to the required center-hole form, workpiece and holder before ordering.<\/p>\n

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

M35 HSS Substrate<\/h4>\n

A cobalt-bearing HSS grade for this product configuration.<\/p>\n<\/div>\n

\n

TiN-Coated Finish<\/h4>\n

The stated finish; confirm coverage and specification for the ordered model.<\/p>\n<\/div>\n

\n

Two Tool Ends<\/h4>\n

The drawing shows cutting features at both ends.<\/p>\n<\/div>\n

\n

Seven Listed Sizes<\/h4>\n

Select d, d1, L and L1 from the exact size row.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Centering Applications<\/h3>\n

Use the specified end to prepare a center hole for turning between centers or to establish a starting location for a subsequent drilling operation, where its geometry is suitable. Review the workpiece grade, machine setup, holder and coolant before selecting cutting data.<\/p>\n

Application Note:<\/strong> The diagram labels two included angles but does not identify a center-hole standard or provide a finished-hole accuracy claim. Confirm the end geometry and depth against your drawing.<\/div>\n<\/section>\n
\n

Workpiece Material Selection<\/h3>\n

Provide the exact workpiece grade and hardness when requesting a starting speed and feed. M35 substrate and TiN finish describe the tool; the dimension chart does not establish suitability or cutting data for every steel, stainless steel, cast iron or nonferrous alloy.<\/p>\n<\/section>\n
