Irwin 117-pc Machine Screw / Fractional / Metric Tap & Hex Die and Drill Bit Deluxe Set

The Irwin 117-pc Machine Screw / Fractional / Metric Tap & Hex Die and Drill Bit Deluxe Set is a hand-threading set built for thread repair, thread cutting, and general maintenance work. This is a tap and die set designed for creating new threads and restoring damaged threads in maintenance, automotive, and shop applications. Model number 26377. If you need one kit that covers standard machine screw sizes, fractional sizes, and metric sizes, this is the kind of set that earns its space on the bench.

What makes this set useful is the range. IRWIN built it as a deluxe mix of the sizes people actually reach for, not a stripped-down starter kit that leaves out the oddball sizes you end up needing on repair work. It includes assorted machine screw plug taps and hex dies, fractional plug taps and dies, metric plug taps and dies, pipe thread tools, 36 drill bits, and 5 spiral flute extractors. That means you can go from drilling and extracting a damaged fastener to cutting clean replacement threads with one case instead of piecing the job together from several sets.

The tools are intended for hand-threading, which matters if you are chasing threads carefully, cleaning up damaged holes, or working on parts where feel and control matter more than raw speed. IRWIN calls out high carbon steel construction in its product description, and the set is built around the kind of accuracy that maintenance techs, auto repair shops, and serious DIY users expect when thread fit actually matters. This is not a gimmick kit. It is a broad service set for real repair work.

On the practical side, the included threading tools help you work through the full process. You get an adjustable handle tap wrench, a 2-in-1 tap wrench, a T-handle wrench, die stocks, and thread pitch gauges, so the set is not just a pile of cutting pieces without a way to use them. That makes a difference when you are switching between smaller machine screw work and larger fractional or metric repairs. The tap wrench size range is listed at 0 to 1/2 inch, giving the set useful flexibility across a wide range of common shop jobs.

The carry case is another strong point. A set like this only saves time if the pieces stay organized, and IRWIN includes a blow molded plastic case with dedicated spots for the components. For anyone doing bench work, service calls, or field repairs, that organization matters. You can tell at a glance what is missing, grab the right die or tap faster, and keep the smaller pieces from turning into a mixed pile after a few uses.

This set also stands out because it includes drill bits and extractors, not just taps and dies. That makes it more useful for repair work than a basic threading set. If a bolt is broken, rusted, or cross-threaded, the job often starts with removal and prep before you ever touch a tap. Having the drill bits and spiral flute extractors in the same kit makes this a better fit for automotive service, equipment maintenance, and restoration work where damaged fasteners are part of the job.

Who should buy it? This set makes sense for mechanics, maintenance departments, fabrication shops, farm and fleet service, and serious home shops that need both SAE and metric thread repair coverage. It is also a smart buy for anyone who would rather own one deeper kit than keep buying missing sizes one at a time. If you only need to chase one or two common sizes once a year, this is more set than you need. If you regularly repair threads, clean up damaged holes, or work across multiple fastener standards, this is the right kind of all-in-one kit.

A real bench kit, not a stripped-down thread chaser

The Irwin 117-pc Machine Screw / Fractional / Metric Tap & Hex Die and Drill Bit Deluxe Set makes sense for the guy who actually fixes things, not the guy who wants the cheapest box with a few common taps in it.
