Kennedy® Soft Scroll Jaws to Suit Pratt Burnard Chucks

For Standard, Super Precision, Griptru, All Steel (type 78), Pratt Burnard old type and Hardinge chucks.

3 Jaw Sets

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.

Extra Heavy-Load Springs Colour Coded Yellow

Carver Bar Clamps

Finished in a bright orange epoxy coating for durability. For tough jobs in engineering applications. Carver bar clamps are supplied complete, with notched bar and two reversible jaws, easily positioned to workpiece before tightening.

Standard Duty Clamp - Long

Precision Ground Flat Stock (18")

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.

Kennedy® Heavy-Duty Industrial Keyed Drill Chuck

Fully hardened and ground working parts. The jaws are centre ground for alignment and concentricity. Keyholes and teeth are fully hardened for durability and wear resistance. To correctly tighten your keyed drill chuck use all key holes in turn to guarantee even pressure and maximum grip. Suitable for use on machine tools and all types of industrial power tools. Supplied with key. Manufactured to DIN 6349.

Self-Centring Geared Scroll Lathe Chucks

Produced to a well proven design for universal application. Scrolls are forged, balanced and hardened. Thread flanks are ground on both sides. All models have grease nipples for easy lubrication and are supplied with two sets of solid jaws - internal and external stepped.

Type 3274 Cast Iron 3 Jaw Plain Back Chuck

Front mounting. DIN 6350 (form A). 3 Jaw. Plain back with adaptor recess.

Kobe™ Keyed Drill Chucks

Fully hardened and ground for durability and wear resistance. Suitable for use with portable power tools. Supplied with key.

Interchangeable Insert Centres

For greater flexibility. Bodies and points manufactured from hardened and ground high grade tool steel, for improved resistance to wear extending tool operating life. Precision manufactured bearings evenly distribute axial load for smooth operation, reducing friction and heat build up. The bearings are protected by seals to prevent dirt and coolant ingress. Modern bevel head design allows unhindered approach of toolholders and lathe tools to the workpiece.

Type 614 A

Supplied without inserts.

Atlas? Swivel Base Vices

Plain jaw milling machine vices are used for holding work that has parallel sides. The swivel base is graduated in degrees and allows the vice to swivel in the horizontal plane. The swivel base gives the vice a greater degree of versatility, but should be avoided when carrying out heavy rough cutting operations because it reduces the rigidity of the setup. Manufactured in accordance with stringent quality criteria and moving parts are tested for parallelism and perpendicularity in no less than eight tests - all to minute tolerances. All models are designed for milling, planing and drilling applications and are available with or without swivel bases.

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.
