Bicos 49pc Thread Chaser Set — Metric & SAE Taps and Dies, Color-Coded Case, Hex Bodies

Bicos 49-piece thread chaser set is a complete metric and SAE kit of taps, dies, and thread files designed to restore and cut clean threads on bolts and fasteners. This compact kit combines 22 taps, 24 dies and three thread files to cover common UNC, UNF and metric sizes so you can repair damaged threads or machine new ones without hunting for individual tools. Each piece is organized in a labeled case with color-coded dies and taps for fast identification; hex-shaped bodies accept a socket wrench for higher torque. The tools are steel with protective black oxide or zinc finishes to reduce corrosion and extend usable life.

Which sizes come in the set and will it cover my projects?

The Bicos kit includes a broad range of standard sizes to fit many automotive, household and workshop fasteners. It contains popular imperial sizes like 1/4", 5/16", 3/8", 1/2", 7/16" and 9/16", plus metric taps and dies from M6 through M14. Color coding separates UNC, UNF and metric pieces so you can quickly choose the correct tool for the job.

• Covers UNC and UNF imperial sizes: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16".
• Metric range: M6, M8, M10, M11, M12, M14 for common machine and automotive threads.
• Includes three thread files to restore damaged pitches and minor burrs.

How durable are the taps, dies and finishes?

Each tool is made from hardened steel to hold a cutting edge under repeated use. The taps and dies receive a black oxide or zinc coating to improve corrosion resistance and reduce surface wear during storage and use. With proper use and lubrication these tools withstand typical workshop demands.

• Hardened steel construction for wear resistance.
• Black oxide or zinc finish protects against rust.
• Hex-shaped bodies allow more secure grip and higher torque application.

What accessories and storage features simplify use?

The set arrives in a molded storage case that keeps every tap, die and file in its place and clearly labeled for quick selection. Dies and taps are color-coded—silver for UNC, black for UNF and gold for metric—so you can visually pick the right standard. The hexagonal shape of each piece fits a socket wrench, and the case makes it convenient to take the set on-site.

• Molded carrying case with individual slots and printed size labels.
• Color-coded pieces for fast standard identification.
• Hex bodies designed to be used with socket wrenches or tap handles.

When should I use the thread files versus taps and dies?

Thread files are best for cleaning shallow damage, restoring pitch, or smoothing burrs on studs and external threads without removing much material. Use taps to re-cut or restore internal threads in holes and dies to re-cut or refresh external threads on bolts and studs. For severe damage you may need a combination of a file to remove burrs followed by a tap or die to re-establish correct form.

• Thread files: minor repairs and pitch alignment on external threads.
• Taps: restore or cut internal threads in nuts and tapped holes.
• Dies: re-cut external threads on bolts and threaded rods.
