Specification note: IRWIN's official product page confirms model 97606 as the 66-piece Machine Screw / Fractional & Hex Die Set. Retailer technical listings differ in how they identify the tap/die material, so the safest product-listing description is to identify the set by its official model number rather than assigning a single material specification without qualification.

Complete Threading Accessories
In addition to the taps and dies, the kit includes several holders and measuring tools. The package contains adjustable die stocks for the 1-inch, 1-7/16-inch, and 1-13/16-inch hex dies, a plain die stock for the 5/8-inch dies, adjustable-handle tap wrenches, a two-in-one tap wrench, a T-handle wrench, and an 18-leaf standard thread gauge.
This combination allows the user to cut or restore internal threads with taps and external threads with dies without having to purchase the basic holding tools separately.
Practical Applications
The IRWIN 97606 set is useful for:
Repairing damaged threads
Restoring worn fastener threads
Creating new internal threads
Cutting external threads on suitable stock
Automotive maintenance
Machinery repair
Equipment maintenance
Metal fabrication
General mechanical workshop work
Organized Storage
All 66 pieces are supplied in a plastic storage case, allowing the taps, dies, holders, and measuring tools to remain organized between jobs. The case also makes it easier to transport the complete kit to maintenance areas or job sites.
Why Choose the IRWIN 66-Piece Set?
The IRWIN 97606 is designed as an all-around inch threading solution rather than a small selection of individual taps and dies. Its combination of machine-screw sizes, fractional NC/NF threads, NPT pipe threads, matching hex dies, multiple holders, and a thread gauge gives technicians a versatile kit for both thread creation and thread repair.
For workshops that regularly encounter different inch-threaded fasteners and components, this 66-piece configuration provides broad coverage while keeping the required tooling together in one case.
