HSS and HSS-E spiral flute, straight flute and forming taps.

Tough, Versatile HSS Threading Tools
High-speed steel taps for general machining, fabrication, repair, and production — a tough, serviceable option for standard threads and application-specific geometries.
Use high-speed steel (HSS) where toughness, practical tooling cost, and application flexibility are central to the threading process.
A practical configuration for suitable short-chipping materials and hole conditions after application review.
Designed to direct chips forward in suitable through-hole applications when the material and process support that strategy.
Designed to help evacuate chips back toward the entry in suitable blind-hole applications.
Chipless thread forming can be evaluated for compatible ductile materials, prepared-hole control, lubrication, and machine conditions.
Provide the thread designation and standard, class or tolerance, thread depth, hole type, prepared-hole size, workpiece material and hardness, machine, holder, coolant or lubricant, and expected volume. JIAYI will evaluate the tap style, cutting material, geometry, and treatment after these inputs are confirmed.

View ProductsWe are still adding this range to our online catalog. These tools are available made to order: send your drawing or sample and we will quote sizes, lead time and price, or contact our team for current availability.
Tools in this category are produced on request to your drawing, sample or specification. Send us your requirements and our engineers will reply within 24 hours.
Toughness and serviceability. HSS offers a practical balance of cutting capability, edge toughness, and serviceability for a broad range of threading work.
Controlled grinding. Thread profile, pitch, chamfer, flute geometry, and cutting edges are produced and inspected against the confirmed tool specification.
Application engineering. JIAYI engineers help match the tap style and treatment to the thread, material, hole condition, machine, and production objective.
Send a drawing, an existing tool, or a representative sample together with the thread specification, workpiece material, hole condition, and machine data. We will review the geometry and prepare a quotation after technical confirmation.
