grinders introduction performance versatility quality when it comes to fine finishing applications such as die grinding or de-burring no tools are better suited for the job than dotco® grinders dotco s reputation for durability dependability and versatility is among the highest for fine finishing applications this is the result of years of continuous improvements in engineering design and manufacturing processes dotco grinders are designed with the operator in mind they are small lightweight and comfortable to use without sacrificing durability plus they incorporate elastomer coatings and perfectly balanced moving parts to keep vibration to a minimum this optimal combination of tool characteristics allows the operator to focus doing the best job possible in the least amount of time grinder abrasives guide precision grinders carbide bur and mounted wheel grinders used in finishing applications that require a high degree of durability cone and plug wheels used for general purpose grinding work on mild steel stainless steel metal alloys and cast steel applications include s grinding and smoothing s beveling workpiece edges s internal grinding fillets corners prior to welding s mild bending contours s general grinding in confined areas type 1 wheels used on portable horizontal shaft tools applications include s notch free grinding s smoothing out weld seams s removing seam lines s pre-weld cleaning s grinding concrete or from castings masonry products type 1 cut-off wheels applications include cutting carbon and stainless steel ferrous metals and cast iron type 6 11 cup wheels used on right angle or vertical shaft tools s type 6 ­ straight cup wheels s type 11 ­ flared cup wheels type 27/28 depressed center wheels type 27 wheels are used at an angle to the workpiece between 30º and 45º these wheels do not flat grind type 28 wheels are saucer shaped wheels which are contoured to provide a correct built-in grinding angle consequently type 28 wheels may be used for flat contact on the workpiece tough tools for tough jobs cleco® and buckeye® grinders meet the demanding requirements of industries including shipbuilding pipe fabricating transportation equipment manufacturing and welding applications since these types of applications typically require a high material removal rate cleco and buckeye grinders incorporate high horsepower/high rpm motors to achieve maximum durability cleco and buckeye grinders use top quality precision components and motor assemblies are protected by either aluminum or steel housings type 1 wheel grinders page 19 type 1 cut off wheel grinders page 20 right angle grinders page 16 precision grinders page 10 type 27 depressed center wheel cup wheel grinders page 22 extended inline grinders page 14 inline grinders page 12 cone or plug wheel grinders page 18 type 27 depressed center wheel grinders page 21 8 warning face eye protection must be worn while operating power tools per ansi b186.1 cutting tool maximum speed rating must equal or exceed speed of air tool 90psi 620 kpa follow cutting tool manufacturer s mounting operating instructions tools must be equipped with lock-off lever to be ce compliant warning face eye protection must be worn while operating power tools per ansi b186.1 cutting tool maximum speed rating must equal or exceed speed of air tool 90psi 620 kpa follow cutting tool manufacturer s mounting operating instructions tools must be equipped with lock-off lever to be ce compliant 9
