How to Select a Thread Type

Confirm the required pipe-thread standard before selecting the cutter. Straight and tapered pipe threads use different thread forms and should not be selected interchangeably.

G / PS / BSP / Rp

Select this series when a straight or parallel internal pipe thread is required.

Rc / PT / ZG / BSPT

Select this series when the internal pipe thread requires a tapered thread form.

Selection Note: Confirm thread standard, nominal inch size, effective thread depth, prepared-hole condition and required connection form before ordering.

Recommended Starting Cutting Parameters

Verified numerical cutting-speed and feed values are not included in the supplied size data. Starting parameters should therefore be selected according to cutter diameter, workpiece material, thread depth, tool overhang, thread form and machine rigidity.

PARAMETER SELECTION BASIS STARTING GUIDANCE
Tốc độ trục chính Cutter diameter / workpiece material Confirm according to selected cutter and workpiece condition
Feed Rate Cutting diameter / thread size / interpolation path Begin conservatively and optimize after thread inspection
Radial Compensation Finished thread size and fit Fine-adjust the interpolation radius after checking the machined thread
Tool Reach L1 / thread depth / machining access Use the shortest practical reach that provides sufficient access
Chip Evacuation Material / hole depth / blind-hole condition Use suitable air, mist or coolant according to the application

Application Guidance

  • Thread Standard: Confirm whether the required connection uses a straight or tapered pipe thread before selecting the cutter.
  • Nominal Size: Match the required inch thread designation to the applicable size chart.
  • Prepared Hole: Machine the required hole before thread milling and confirm sufficient cutter clearance.
  • Effective Length L1: Select sufficient reach for the required thread depth while minimizing unnecessary tool overhang.
  • Thread Compensation: Use CNC tool-path compensation to fine-adjust the finished thread size after inspection.
  • Taper Threads: Program the required tapered interpolation path according to the specified pipe-thread standard.
  • Chip Evacuation: Maintain suitable chip evacuation, especially for blind-hole and deeper internal-thread applications.

FAQ & Downloads

Common selection, application and ordering questions for solid carbide thread mills for inch internal pipe threads.

Product & Application FAQs

Selection guidance for straight and tapered inch internal pipe-thread milling.

What inch thread standards are available?

The listed series covers G, PS, BSP and Rp straight or parallel internal pipe threads, together with Rc, PT, ZG and BSPT taper internal pipe threads.

What is the difference between straight and taper pipe threads?

Straight or parallel pipe threads maintain a consistent thread diameter along the threaded section, while taper pipe threads use a tapered thread form. Select the cutter according to the required connection standard rather than nominal inch size alone.

Can the same cutter machine both straight and taper pipe threads?

Not as a general rule. Straight and tapered pipe threads use different thread-form and tool-path requirements. Confirm the required thread standard before selecting the cutter.

Can these thread mills be used for blind holes?

Yes, provided the prepared-hole depth, effective tool length, required thread depth and bottom clearance are suitable. Chip evacuation should also be considered for deeper blind-hole applications.

How is the finished thread size adjusted?

The finished thread size can be fine-adjusted through the CNC interpolation radius or tool compensation after checking the machined thread.

How should I select the correct cutter size?

Confirm the thread standard, nominal inch size, straight or taper form, prepared-hole diameter and required thread depth. Then match the cutting diameter d, effective length L1, shank diameter D and overall length L to the applicable size chart.

What workpiece materials can be machined?

The carbide and coating configuration should be selected according to the workpiece material, hardness and cutting conditions. Provide the material grade when requesting a tooling recommendation.

Ordering & Customization FAQs

Information for distributors, tooling brands and industrial buyers sourcing standard or custom inch pipe thread mills.

What information should I provide for selection?

Please provide the thread standard, nominal inch size, straight or taper form, prepared-hole diameter, required thread depth, workpiece material and order quantity.

Can you manufacture custom inch internal thread mills?

Yes. Cutting diameter d, effective length L1, shank diameter D, overall length L, thread-form geometry and coating can be reviewed according to the required pipe-thread standard or component drawing.

Are OEM marking and private-label packaging available?

Yes. Laser marking, thread-standard identification, custom labels, protective tubes and private-label packaging can be reviewed according to the confirmed specification and order quantity.

What is the lead time?

In-stock standard sizes can normally be prepared for shipment within 1–3 days. Custom thread mill lead time is confirmed after thread standard, dimensions, coating, quantity and packaging requirements are approved.
