Product Description:
This chaser tangential die is designed for fast, accurate external threading on pipes and bars.
Each chaser is manufactured from premium high speed steel for long tool life and stable performance.
The ground tooth profile delivers clean threads with minimal burrs, reducing finishing time and rework.
Use it in tangential die heads on lathes, pipe threading machines, or dedicated bolt threading equipment.

Key Features

High speed steel body provides excellent toughness, wear resistance, and heat resistance under heavy production loads.

Precision ground teeth ensure consistent thread form, smooth cutting action, and reliable gauging results.

Standard overall length 100 mm with 25 mm width and 10 mm height for easy setup.

Available in ordinary metric pitches from 1.0 mm to 4.0 mm for general thread cutting.

Inch series covers 1 inch threads from 20 TPI down to 6 TPI options.

55° taper pipe models suit BSPT style pipe threads, including 1 inch 28 to 11 TPI.

Interchangeable design lets you quickly reset tangential die heads for different thread standards and pitches.

Specifications

Material for all types is HSS, hardened and tempered for optimum strength and service life.
Standard length is 100 mm, with widths 25 or 28 mm depending on thread range.
Height is 10 mm, matching most common self-opening tangential die heads.
Metric series uses straight threads, while taper pipe versions follow 55 degree pipe thread profiles.

Applications

These tangential chasers are ideal for production threading of bolts, couplings, nipples, and hydraulic fittings.
Use them on carbon steels, alloy steels, stainless steels, and many non ferrous materials.
Consistent thread quality helps seals seat correctly and extends service life of threaded connections.

Ordering and Customization

Each set is supplied matched and marked, so you can maintain correct sequence during installation.
Chasers are packed in protective boxes to prevent edge damage during storage and transportation.
Custom pitches, special profiles, and alternative lengths are available for OEM or replacement requirements.
