Kolvoii 52-Piece Metric Tap & Die Set – M6–M24, Heavy-Duty GCr15 Steel, Thread Repair Kit

All-in-One Metric Threading Solution

Kolvoii delivers a comprehensive 52-piece kit that covers coarse and fine metric taps and dies from M6×0.75 to M24×3.0. This ready-to-work set supports re-threading tasks across engines, machinery, and metalwork, offering flexibility for repairs and maintenance without swapping between multiple tools.

• Broad size range including both coarse and fine threads for versatility.
• Designed to handle typical engine repairs and heavy machinery maintenance with ease.

Industrial-Grade Durability

The tools are crafted from GCr15 bearing steel and hardened to 60 HRC, delivering impressive wear resistance and resilience under high torque. Tolerances are engineered for reliable, repeatable results across repeated use.

• Wear resistance supports long service life in demanding environments.
• High-torque capability helps maintain cutting edge integrity during use.

Precision Threading Performance

Each tap and die features CNC-machined cutting teeth that produce clean, accurate threads on a wide range of metals, including carbon steel, stainless steel, aluminum, brass, copper, and cast iron. Expect smooth starts and consistent pitch across applications.

• Compatible with diverse metals for various projects.
• Enhanced threading accuracy reduces rework and improves fitment quality.

Pitch Gauge and Extractors

A metric pitch gauge helps identify thread types at a glance, while spiral-flute extractors (EZ-Out style) assist in removing broken bolts or studs without damaging surrounding threads.

• Quick thread type identification to choose the right tool.
• Safe extraction of broken fasteners to protect surrounding material.

Enhanced Usability Features

Adjustable tap and die wrenches accommodate a variety of sizes and can be tuned for specific applications. A center punch and screwdriver aid in starting threads accurately, reducing cross-threading and giving you more control.

• Fine-tuning ensures precise, repeatable results.
• Helpful accessories streamline alignment and starting the cut.

Complete Accessory Kit

Everything you need is included: 20 taps, 20 dies, a tap wrench, die wrench with adapter, a T-handle wrench, an adjustable tap wrench, spring-flute extractors (3–18 mm), a flat screwdriver, a center punch, and a metric pitch gauge—neatly stored in a durable blow-molded case for portability and organization.

• Extensive tooling set covers a broad spectrum of threading tasks.
• Durable case keeps components organized and ready for transport or on-site work.

Note: This kit offers a robust threading solution for professional shops and serious DIYers. Real-world results depend on material, condition, and technique, and benefits are presented as possibilities rather than guarantees.
