Draper Imperial BSPT Thread Chaser 1" - M4562540

Draper Tools is a UK manufacturer of professional hand tools and tooling systems, supplying tradespeople and engineers with pipe threading equipment, cutting tools, and precision hand tools since 1919. Their pipe threading range covers ratchet threading kits, individual dies in BSP and metric standards, thread chasers for cleaning and restoring damaged threads, and the handles, holders, and guides required to use them correctly. This page covers the Draper Imperial BSPT Thread Chaser, available in 4 size options: 1", 1-1/4", 1/2", 3/4".

Draper threading dies, thread chasers, and die holders are the individual components of a pipe threading system, allowing existing ratchet handles to be extended with additional die sizes or to restore threading capability when a specific die wears or is required for a size not included in the original kit. Thread chasers clean and restore damaged external threads without cutting new material.

Where this product is used

Draper dies, chasers, and holders are used across pipe installation and repair:

• Adding metric or imperial pipe thread sizes to an existing threading system without purchasing a full new kit.
• Restoring damaged or corroded external threads on pipe, rod, and fittings using thread chasers that follow the existing thread form.
• Replacing worn individual dies in a threading set rather than replacing the complete kit.

Selecting the right option

Match the die or chaser to the thread standard and size required — Draper offers metric conduit dies and imperial BSPT chasers. The die holder and guide provides the correct alignment and support for the die during use and must be matched to the die diameter. Thread chasers restore damaged threads without cutting new ones and are the correct tool when the thread form is present but damaged or contaminated.
