Solid Carbide Full-Profile Metric Thread Mill for Internal Threads With Black Coating

A full-profile metric thread mill uses multiple pitch-specific cutting teeth to generate several thread turns during CNC circular or helical interpolation. Unlike a single-form thread mill with one cutting profile, the full-profile design is intended for efficient repeat machining of confirmed metric thread specifications while allowing the finished thread diameter to be fine-adjusted through the CNC tool path.

A single-form thread mill uses one thread-form cutting profile and normally follows a longer helical path to generate the required thread length. A full-profile thread mill has multiple teeth matched to the selected pitch, allowing several thread turns to be generated simultaneously. Full-profile tools are generally preferred for repeated machining of a confirmed pitch, while single-form tools provide greater flexibility for varying thread depths and compatible diameters.

In compatible applications, a pitch-specific full-profile thread mill may be used for different thread diameters that share the same pitch, provided the cutter diameter, thread form, prepared-hole size, working length and machining clearance are suitable. The final thread diameter is controlled through the programmed interpolation radius.

Yes, provided the prepared-hole depth, thread depth, working length L1 and bottom clearance are suitable. Blind-hole applications also require effective chip evacuation to reduce chip recutting. Air blow, mist or suitable coolant can be selected according to the workpiece material and hole depth.

Flute count is selected according to cutter diameter, pitch, tool-body strength and chip-space requirements. Smaller or selected thread-mill sizes may use three flutes, while larger configurations commonly use four flutes. The standard size matrix should therefore be checked rather than assuming one flute count for the complete series.

The series can be configured for carbon steel, alloy steel, stainless steel, cast iron and selected non-ferrous materials. The appropriate carbide grade, cutting-edge preparation, coating and cutting parameters should be matched to the workpiece grade, hardness, thread pitch and thread depth.

A tap follows the thread helix with a fixed-size tool, while a thread mill generates the thread through CNC interpolation. Thread milling allows the finished diameter to be adjusted through the tool path and can provide greater control in blind-hole and precision-thread applications. Tapping may still provide shorter cycle times in some high-volume applications, so the appropriate process depends on thread size, material and production requirements.

The supplied standard range covers selected metric thread sizes from M3 to M24 with pitches from 0.5 to 3.0 mm. Cutting diameters d range from approximately Ø2.35 to Ø16 mm, working lengths L1 from 6 to 42 mm, shank diameters D from Ø4 to Ø16 mm and overall lengths L from 50 to 100 mm. Three-flute and four-flute configurations are supplied according to size.

Yes. Cutting diameter d, working length L1, shank diameter D, overall length L, flute configuration, full-profile tooth geometry, chip grooves, coating and selected thread specifications can be reviewed according to the machining application or component drawing.

Yes. Thread size, pitch, tool codes, logos and batch information can be laser marked where shank space permits. Application-specific coatings, custom labels, protective tubes and private-label packaging can also be reviewed according to order quantity and confirmed specifications.

In-stock standard sizes can normally be prepared for shipment within 1–3 days. Custom full-profile thread mills require confirmation of the thread size, pitch, dimensions, carbide grade, coating, quantity and packaging requirements before the production lead time is confirmed.
