Overview

The TOMMARS 51-Pc Jumbo Tap and Die Set is a robust threading toolkit designed for a wide range of projects, from fresh builds to repairs. It covers SAE sizes from 1/4-20 NC to 1-14 NF, offering options for both internal taps and external dies on common metal work. The kit is built to support clean, precise cuts with ease and confidence.

What’s included and how it helps

Inside you will find the essential tools for efficient threading and rethreading. The kit includes a T-handle tap wrench, a die wrench with a 1-1/2 inch OD adapter, a flat screwdriver, a centre punch, and spiral flute extractors spanning 3 mm to 18 mm. These components work together to enable quick setup, stable control, and reliable thread formation.

• T-handle tap wrench for comfortable leverage and steady control
• Die wrench with adapter for swift changes and alignment
• Spiral flute extractors 3 mm to 18 mm for removing damaged threads
• Flat screwdriver and centre punch for setup and alignment

These tools support both internal and external threading, helping you create new connections or recover damaged ones with less guesswork and more predictability.

Durability and precision

Each tap and die is crafted from long lasting alloy steel, offering resilience for repeated use. The cutting teeth are precision ground and hardened to about 60 HRC, delivering consistent performance across the kit. A rust resistant satin finish reduces friction, aiding smoother cuts and longer tool life.

Materials and metals you can work with

Designed for a variety of metals including carbon steel, cast iron, aluminum, brass, copper and stainless steel. You can rely on the set to create new threads or restore damaged ones while maintaining alignment and accuracy in your project.

Practical usage tips

For best results, pair the correct size tap with its matching die, keep chips cleared, and apply steady, straight feeding pressure. This approach supports reliable thread formation and minimizes the need for retapping.
