\u25c6<\/span>2D\u20135D Indexable U-Drill Overview<\/h2>\n
<\/div>\n

This indexable U-drill range uses replaceable center and peripheral inserts for CNC holemaking at nominal depth ratios of 2\u00d7D to 5\u00d7D. The selection charts group the drill bodies by WC-style and SP-style insert pockets. Choose the body by finished hole diameter and required depth, then confirm its exact insert codes, shank, screws and coolant connection. Through-tool coolant and suitable chip evacuation are especially relevant for longer 4\u00d7D and 5\u00d7D configurations. Available combinations depend on the individual drill-body drawing.<\/p>\n

The reference charts show WC drill-diameter groups from 14 to 60 mm and SP groups from 13 to 52 mm. They do not establish that every diameter is offered at every depth ratio.<\/p>\n<\/div>\n<\/section>\n

Key Configuration<\/h2>\n
<\/div>\n
\n
Depth ratio:<\/strong> 2\u00d7D \/ 3\u00d7D \/ 4\u00d7D \/ 5\u00d7D; availability by complete body model.<\/div>\n
Insert system:<\/strong> WC or SP pocket family; exact center and peripheral inserts confirmed per drill body.<\/div>\n
Toolholding:<\/strong> Confirm shank diameter, shank style and machine holder from the approved drawing.<\/div>\n
Coolant:<\/strong> Confirm through-tool coolant provision, connection and operating conditions for the selected body.<\/div>\n
Workpiece:<\/strong> Grade-specific selection for steel, stainless steel, cast iron or other approved materials.<\/div>\n<\/div>\n<\/section>\n

WC & SP Drill-Body Selection<\/h2>\n
<\/div>\n

The reference drawings depict a triangular WC pocket and a square SP pocket. Choose the body and corresponding insert designation together; pocket geometry, grade and hardware must match the complete model.<\/p>\n

For blind holes, specify the required bottom shape and remaining cone or center height. An SP insert does not automatically produce a true flat-bottom hole.<\/p>\n<\/section>\n

Product Images & Applications<\/h2>\n
<\/div>\n

Use in compatible CNC drilling setups where the body diameter, depth ratio, pocket and coolant delivery match the application. For extended-depth cuts, check setup rigidity, chip evacuation and the manufacturer’s starting conditions before production.<\/p>\n
