Gesswein Abrasive Stones

Gesswein Abrasive Stones are designed to be used directly after machining, or spark eroding, in the preparation of surfaces for final polishing. All stones are manufactured to high standards from a liquid mix of the abrasive and the bonding agent, which is then fired in a thermostatically controlled kiln to ensure uniform distribution of the abrasive particles in each stone.

The stones are cut after firing and ground to size when cold, this process yields consistent quality and performance. Care should be taken in use and storage to prevent contamination from one grit, or type, to another. It is recommended that Kemet Stoning Oil is used as a lubricant with the stones.

Gesswein Diemaker

(Beige/light brown) This range of stones has established itself as one of the most popular in use today. Fast cutting with moderate breakdown, the DF can be used on both hard and soft steels, and is also suitable for some non-ferrous materials. Able to be used by hand or in profiling machines.

  • By far our most popular finishing stone.
  • This Medium-hard, aluminum oxide stone combines the characteristics of fast cutting and moderate breakdown.
  • Ideal for general purpose stoning on hard and soft grades of tool steel such as H-13, P-21, SS420 and pre-finishing on aluminum.
  • The precise grit size of aluminum oxide is evenly distributed throughout each stone to ensure consistent cutting time and time again.
  • Can be used by hand or in a reciprocating profiler.

gesswein DF stones

Gesswein EDM Orange

(Orange) stones are designed to remove the tough hard scale left by ElectroDischarge Machining. These stones contain extra sharp particles of Aluminium Oxide, together with a small amount of Chromium Oxide, within a special bond, which enables them to follow contours. May be used by hand, or in a profiler.

  • Remove the tough, hard scale left by the EDM process much faster than any of our other finishing stones.
  • Contains extra-sharp premium-grade aluminum oxide for fast cutting action.
  • Special clay bond enables the EDM stones to hold their shape well for working small details and sharp corners.
  • Breaks down slowly, cuts fast and resists loading.

Gesswein EDM

Gesswein EDM Blue

(Blue) stones are a natural development from the extremely popular EDM (orange) stones. Due to the inclusion of a small amount of cobalt, they are harder than EDM, maintaining their strength even in small section sizes, with good resistance to loading. Excellent for use in profiling or ultrasonic machines. EDM Blue stones break down slowly and cut fast. Very good for detailed work.

  • Harder than our regular EDM Stones and designed specifically to remove the tough, hard scale left by the EDM process.
  • Contains extra-sharp premium-grade aluminum oxide for fast cutting action plus a small amount of cobalt blue for added hardness.
  • Breaks down slowly and cuts fast.
  • Resists breakage and specifically designed for use in reciprocating profilers.

gesswein edm stones

Gesswein Oil Treated

These stones have been increasing in popularity over recent years. Able to be used on hard or soft mould and die steels, OT stones are made from white premium grade Aluminium Oxide, in a medium/hard bond, which is soaked in oil during the manufacturing process. This enables the stones to be used, if required, without lubrication. OT stones maintain good shape during use, and are excellent for processing machined or even EDM surfaces. Good for use in profiling machines.

  • Excellent for machined surfaces.
  • Fine cutting ability.
  • Medium-hard stone with white aluminium oxide soaked with oil.
  • Can be used without additional lubrication.
  • Holds shape well for finishing mould details. Moderate breakdown.
  • Often used for EDM removal. Special oil treatment prevents loading.

Gesswein premium white polishing stones

Gesswein RA

Manufactured from very hard Aluminium Oxide within a resin bond to give flexibility and resilience. Excellent for corners, deep ribs and areas of fine detail, these stones produce a finer finish than other stones of the same grit. RA stones are extremely versatile and may be used by hand, or with profiler or ultrasonic.

  • Aluminium oxide abrasive bonded together with a unique organic resin bond gives these stones great resiliency.
  • Retain their shape and have a flexing capability, making them resistant to breakage even during heavy use.
  • Leave a finer finish with less stock removal than other stones of the same grit.
  • Can be used by hand, in a profiler or in an ultrasonic polisher on all mould and die steels.
  • Ideal for finishing slots, deep ribs and other hard-to-reach mould areas and can also be used to remove EDM scale.
