Three stages. One practical set for hand threading.
SWAGIN HSS hand tap sets combine taper, plug/intermediate and bottoming taps for suitable manual internal threading operations. Share your thread size, material, quantity and drawing reference for a standard, bulk, export or custom enquiry.
Product overview
A three-piece hand tap set provides taper, plug/intermediate and bottoming options for suitable manual threading work in prepared holes. The correct sequence depends on the hole type, thread depth, material, alignment and component requirement.
Product-family information is a starting point. Confirm size-specific dimensions, grade, tolerance, availability and commercial terms in the quotation.
Built around the application
Review the set against the thread standard, workpiece material, hole type, depth and production quantity. No universal suitability or tool-life result is guaranteed.
Taper, plug/intermediate and bottoming taps support staged internal thread formation in a prepared hole.
Discuss M2, M35 or M42 according to the workpiece material and application.
Supports controlled thread formation and dimensional review for the selected configuration.
Metric, British, unified and pipe-thread requirements can be reviewed against the exact specification.
Select 6-thread taper, 4-thread plug/intermediate or 2-thread bottoming geometry where suitable.
Share size-wise quantities, drawings, dimensions and commercial requirements for quotation.

Unified thread families are covered by ASME B1.1. This practical industry list includes common metric, Unified, British and pipe series; it is not every specialist thread standard worldwide.
Set contents
Use each lead according to the entry, thread depth and hole condition. The corresponding configuration is confirmed in the quotation.
Longer entry lead for progressively starting the thread.
Intermediate lead for continuing a tapping operation.
Shorter lead for finishing nearer the bottom of a prepared blind hole.
Application examples
Discuss the drawing, material, machine, hole and production quantity with the manufacturer. These examples do not claim customer or project approval.
