Solid Carbide No-Pilot-Hole Thread Mill for Combined Hole Making and Thread Milling

It means the tool is designed to generate the core hole and mill the 60° internal thread in a combined CNC cycle, so a separate drilling operation is not required. This does not mean the tool can be fed like a conventional tap. It requires the programmed entry, helical interpolation, centre return and retraction sequence specified for this tool family.

The steel series is configured primarily for carbon steel, alloy steel and pre-hardened steel, with selected stainless-steel applications. It covers M3–M12 and uses four flutes. The low-friction DLC series is intended for aluminium, copper and suitable non-ferrous or non-metallic materials; it covers M1.6–M12 and uses two, three or four flutes according to size. Select the version by workpiece material rather than coating colour alone.

Start with the workpiece material, exact metric thread size, pitch and required thread depth. Then match the dedicated standard model and confirm cutter diameter d1, cutting length L1, shank diameter D, overall length L, flute count and coolant type. Also confirm bottom clearance, holder access and whether the machine can execute the required helical interpolation cycle.

No. Each standard tool code is matched to a specific metric thread size and pitch because the tool must generate both the core hole and the finished thread geometry. Choose the exact model shown in the dimensional table. A different diameter or pitch requires another standard code or an approved custom design.

Yes. Blind-hole machining is a primary application, provided the programmed depth leaves adequate bottom clearance and the toolpath supports chip evacuation. Confirm L1, entry position, centre-return movement, coolant delivery and retraction before machining. Avoid contact between the tool shoulder or shank and the workpiece surface.

The steel series is recommended for carbon steel, alloy steel and pre-hardened steel and can be applied to selected stainless steels after confirming cutting conditions. The DLC series is recommended for aluminium and copper and can also be reviewed for plastics and acrylic. Do not use the DLC version for ferrous materials unless the application has been specifically approved.

Use the approved CNC cycle for the selected model: position at the helical start point, interpolate to generate the core hole and thread, return to the hole centre and retract. The DLC process chart also includes a chamfering step before returning to the start point. Use a precision low-runout holder and verify the first finished thread with the correct plug gauge before batch production.

The steel series covers M3–M12, P0.5–P1.75, d1 Ø2.4–Ø9.0 mm, L1 9–26 mm, Ø6 / Ø8 / Ø10 mm shanks and 50 / 60 / 75 mm overall lengths. The DLC series covers M1.6–M12, P0.35–P1.75, d1 Ø1.15–Ø9.6 mm, L1 5–26 mm, Ø4 / Ø6 / Ø8 / Ø10 mm shanks and 50 / 60 / 75 mm overall lengths.

Yes. Custom metric size, pitch, cutter diameter d1, reach L1, shank diameter D, overall length L, flute configuration, bottom-cutting geometry, coolant delivery, carbide grade, edge preparation and coating can be reviewed. Please provide the complete thread callout, component drawing, thread depth, bottom clearance, material, machine and holder restrictions, inspection requirement and quantity.

Yes. Laser marking can include the customer logo, product code, steel or DLC designation, metric size, pitch, coating code and batch number. Application-specific coatings, custom labels, protective tubes and private-label packaging can also be reviewed for distributor and OEM programs.

The minimum order is 10 pieces per size. In-stock standard tools can normally be dispatched within 1–2 working days. Custom-tool lead time is confirmed after the thread specification, steel or DLC version, combined cutting geometry, coolant delivery, dimensions, carbide grade, coating, quantity, inspection requirements, laser marking and packaging are approved.
