The Sealey 28 Piece Tap and Die Set Imperial BSW is a professional threading toolkit designed for creating and repairing British Standard Whitworth threads in engineering, restoration and maintenance applications. This comprehensive set features high-quality alloy steel taps and dies covering eight common BSW sizes from 1/8" to 1/2". Each size includes both taper and plug taps for versatile thread cutting, whilst the split dies incorporate machined lead-ins to ensure smooth, accurate thread formation.
The die holder benefits from a self-centring mechanism that maintains straight and precise thread cutting, reducing the risk of cross-threading or damaged work. Ideal for engineers, mechanics and restoration specialists working with classic British machinery, vintage vehicles or heritage equipment where BSW threads remain standard. The set includes everything required for complete thread cutting and repair work: T-handle and standard tap wrenches for different applications, a die holder, and a BSW thread gauge for accurate identification.
All components are supplied in a sturdy storage case that keeps tools organised and protected between jobs.
