Silver Steel

For tool room and general engineering. Applications include screwdrivers, punches, shafts, axles, pinions, pins, die posts, instrument parts, model parts, taps and drills for mild steel, engraver tools. High carbon content means that it can be hardened to give high wear resistance and chromium content adds strength and hardness.

Precision Ground Flat Stock (500mm)

The dimensional stability of ground flat stock combines with other useful characteristics including excellent resistance to cracking during heat treatment compared with other, more highly alloyed, cold work tools. Relatively soft and easy to machine. High wear resistance after heat treatment. Holds a good cutting edge. Suitable for EDM machining.
Typical applications: widely used in precision tools, machine knives, gauges, jigs, templates, punches, dies and machine parts.
The Cost Cutting Stock: extensive range of widths and thicknesses enables the selection of an appropriate size of ground flat stock to minimise material and machining costs.

Manufactured from BS4659 B01 grade steel equivalent to AISI 01 and Werk. No. 1.2510.

Indexa Die Springs

The heat and surface treatment plus the high quality of steel used in the manufacturing process ensure the springs will bear a high number of stresses without breaking or without appreciable loss of load. Every batch of springs is subject to a rigorous testing procedure to ensure that a consistent quality is maintained. Longer springs should be guided along their course.

Medium Load Springs Colour-Coded Blue

Framework Benches

Simple and economic solutions to the need of production assembly, maintenance and despatch personnel.
18mm FSC compliant chipboard working surface (210kg UDL). Shelves on workstations carry 150kg UDL.
Robust uprights and light grey beam finish. Kits supplied with metal feet and full assembly instructions.

Fixture Components

Material: Medium Carbon Steel. Surface Finish: Manganese Phosphate.

Kennedy® Abrasive Wheel Dressers

Conventional abrasive wheels need truing and regularly dressing to maintain a quality grinding performance, Kennedy single point diamond dressing tools have a single industrial diamond embedded in a cylindrical steel shaft they are suitable for performing both of these applications:

Truing is the process of aligning the periphery of the grinding wheel so that it runs concentric with its axis of rotation. This allows accurate and precise relative motion between the grinding wheel and the part being ground.

Dressing removes dulled abrasive and foreign material that has been embedded into the wheel. This allows the wheel to cut properly. Kennedy diamond dressing tools are mainly used to true straight-faced grinding wheels.
