Drester Diamond Files

"Drester" electroplated diamond files are available in a wide range of over 100 combinations of shape, size & grit.

"Drester" diamond files are suitable for use on carbide, stainless steel, glass, ceramics, ferrites, carbon, graphite, FRP, gold, silver & any materials where conventional files cannot be used.

"Drester" diamond files are made with carefully selected quality diamonds. The high grit protrusion gives fast stock removal even with low working pressures. Our state-of-the-art plant incorporates automatic process control & unique plating technology, which ensures consistent cutting action & long tool life. "Drester" diamond files are the most economical choice for precision work.

Electroplated Diamond / CBN Mounted Points

"Drester" electroplated diamond & cubic boron nitride (CBN) mounted points (grinding pins) are manufactured in a state-of-the-art plant, incorporating automatic process control & unique plating technology. Specially selected grades of blocky natural or synthetic diamond & CBN are used for our pins. This ensures smooth free-cutting action with minimal heat buildup & long service life. Our unique plating process provides exceptionally high bond strength, reducing the risk of premature pull-out of diamond/CBN abrasive grains. The blanks are made of medium carbon steel, which is tougher than ordinary mild steel, in order to minimize bending of the shank during use.

The pins can be used for external & internal grinding of a wide variety of materials. Diamond pins are used for fibre-glass, bakelite (printed circuit boards), carbides, ferrites, graphite, ceramics, glass, etc. CBN pins are used for high speed steels, tool & die steels, cast irons, hardened steels (45 Rc & up), etc.

Standard pins are available in a range of 1mm to 30mm diameter. Alternatively we can manufacture custom made pins to your specifications, and we can also undertake diamond/CBN coating of blanks supplied by you.

Electroplated Diamond Cutoff Wheels

"Drester" electroplated diamond cutoff wheels (slitting saws) are manufactured in a state-of-art plant incorporating automatic process control & unique plating technology. Our process provides exceptionally high bond strength between the diamond grains & the tempered spring steel body, thus minimising the chances of premature failure due to diamond grain pull-out. Tool life is further enhanced by our specially selected tough, blocky grades of synthetic & natural diamond grains.

The electroplated bond ensures exceptional cutting quality & superior surface finishing. This leads to high material removal rate, extremely free-cutting characteristics & low heat buildup (can be used wet or dry).

These saws are ideal for cutting a wide variety of materials, such as fibre-glass, bakelite (printed circuit boards), graphite, carbon, ferrites, asbestos, carbides, MDF, ceramics, bonded abrasives, refractories, colored stones, bone, horn, paper, etc. 

Standard cutoff wheels are available in a range of 100mm (4") to 350mm (14") diameter. For cutting of tool & die steels, high speed steels & steel harder than 45 Rc, we can supply saws coated with cubic boron nitride (CBN).
