Single point "bruited diamond" dressers are made with selected "Congo Rounds" mounted in a matrix. A Single cutting edge is presented to the grinding wheel. Diamonds for single point dressers are selected in accordance with quality and size. The question of using a superior, average or commercial quality depends on the grinding finish required and the machines and working parameters. We are one of the prime manufacturer and supplier of a wide range of Single Point Diamond Dressers that is manufactured from high grade diamonds depending on their structural strength, finishing and degrees of sharpness. These diamonds are mounted in a metal bond with one cutting edge rendered to grinding wheel. We manufacture superior quality assorted Single Point Tools. It is well known that rotating the single point dresser is important to maintain a sharp point, to reduce the wear and tear, and minimize its thermal buildup. For years this process means the drills will routinely loose setscrews, re-indicating the shaft from 20° to 40° with uneven wear and tear as the rotation varies with each machine operator.   Advantages   Longer tool life - ease in usage encourages more frequent rotation, producing more even wear and longer life.   Sturdier design - it withstands 2 to 3 times more torque than other single point dressers, and eliminates excess vibration and chatter.   Brass head reduces heat buildup - diamond tools have increased life over conventional steel tools. In the last few decades, single point diamond dressers have, undoubtedly, emerged as the most widely used diamond dressing tools. The prime reason for the popularity of these tools is the versatility offered by them, as they can be used for truing as well as dressing of grinding wheels.   BRUTED DIAMONDS       'A', 'B', 'C': These Stones are Bruted Type Commercial Quality diamonds.   'AA' Class: These Stones are natural polished stones.   'AAA' Class: These are premium grade Gem quality natural diamonds with 2-3 workable points.   Application The diamond point should contact the grinding wheel slightly below its center and at an inclination of 10-15�.   In feed increments of up to approx. 0.01-0.03 mm per dressing operation are possible.   Shock-like cooling may destroy the diamond.   Carefully place the diamond on the grinding wheel.

Multi Point Diamond Dressers manufactured by SDT is fixed with number of natural diamonds of a quality crystal character fixed into a special wear resistant bond. The diamonds are arranged in different pattern in single layer or multiple layers, depending upon the field of operation. The contact between diamond point and wheel face reduces the unit pressure on each point resulting in a longer tool life with full utilization. Multipoint Diamond Dressers are used for large wide grinding wheels. Advantages    No resetting   No re-lapping   Maintenance free   Higher output   Longer service life   BRUTED DIAMONDS   'A', 'B', 'C': These Stones are Bruted Type Commercial Quality diamonds.   'AA' Class: These Stones are natural polished stones.   'AAA' Class: These are premium grade Gem quality natural diamonds with 2-3 workable points.   APPLICATION    Set the multipoint tool into the center of the grinding wheel.   Depth of cut should not exceed more than 0.01-0.04 mm.   Use plenty of coolant to increase the tool life.   The mounting must be vibration free, with the clamping length as short as possible.

Mounted Point Diamond Dressers is quite similar to that of Multipoint diamond dresser. In this dresser the crushed diamond grit in both Natural & Synthetic grades are set in a several layers in random pattern. With this type of tool, the dressing work is carried out by several small diamonds which together result in excellent performance. To achieve good results, the diamond particles must have at least double the grinding wheel grain to be dressed. Tools with higher diamond content are more efficient in this case. These tools are more suitable for fine and sensitive grinding wheels where a lower surface finish is required.   Advantages    Dressing time is reduced as higher feed rates can be used.    They are tougher & more wear resistance.    These tools can be used completely without any requirement of maintenance.    Extend wheel life by less stock removal per dressing.    No resetting or re-lapping required.    These tools are inexpensive and easy to use.   Bruted Diamond    'A', 'B', 'C': These Stones are Bruted Type Commercial Quality diamonds.   'AA' Class: These Stones are natural polished stones.   'AAA' Class: These are premium grade Gem quality natural diamonds with 2-3 workable points.   Application   Depth of cut should not exceed more than 0.02-0.04 mm.   Use plenty of coolant to increase the tool life.   The mounting must be vibration free, with the clamping length as short as possible.   Multi-point dressers must be used with higher crossfeed velocity rates than single point or blade dressing tools as their effective width is generally much greater.
